In this work, a novel controllable chaotic stirring strategy that basic speed with chaotic mappings is proposed to enhance the solid-liquid mixing state quality. Specially, the modern statistical image analysis technique is introduced to explore the intensification mechanism of the mixing process. Results show that the best experimental conditions are obtained by studying the influence of factors such as the type of chaotic mapping, the speed change time, and the basic speed on the mixing state quality. Moreover, the case in which the basic speed is set to 150 r/min generated by the cascaded Logistic-Cubic chaotic mapping is the best while the speed change time is set to 5 s and the fluctuation threshold is 30. The mixing time of this case is 50 s and the shortest, energy consumption is 1.64 × 104 W/m3 and appropriate, the solid particle suspension quality is 83 and the best. © 2023 Elsevier Ltd

High levels of heavy metals (HMs) are present in municipal solid waste incineration fly ash (MSWI-FA), which requires proper management before landfilling. This study proposes the co-disposal of MSWI-FA and coal fly ash (Coal-FA) using geopolymerization technology. The effects of MSWI-FA content on the mechanical and structural properties of composite geopolymer, the immobilization efficiency and long-term leaching behavior of HMs were investigated for the understanding of the stabilization mechanisms. The geopolymer with the 20 wt.% MSWI-FA achieved the maximum compressive strength of 25.73 MPa, mainly due to the formation of C-A-S-H gels. The compressive strength was less affected by leaching in sulphuric acid-nitric acid (Sul-Nit) leaching solution for 64 days, but decreased by 57.4% (from 25.73 MPa to 10.97 MPa) in the acetic acid (Ace) leaching solution. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis illustrated that C-A-S-H gels were formed, resulting in greater stability of geopolymer in an acid rain environment than in a landfill leachate environment. The leaching behavior of HMs in geopolymers was impacted by the pH of the leaching solution and the properties of HMs. The bulk diffusion model (BDM) of the leaching processes showed that the effective diffusion coefficients (De) of Cd were higher than other HMs (Zn, Pb, and Cr) in the Ace leaching solution, which was consistent with its highest leaching ratio. The leaching behavior of zinc from geopolymer samples in Ace leaching solution was analyzed using the Finite Element Method (FEM). The concentration distribution profile showed a higher relative leaching rate from the geopolymer with 20 wt.% MSWI-FA than that with 40 wt.% MSWI-FA. This research offers a promising and practical approach to solidifing/stabilizing MSWI-FA with Coal-FA. © 2023, The Authors. All rights reserved.

The slow reaction of fly ash (FA) and alkali at room temperature is the main obstacle of industrial applications of FA-based geopolymers. The effect of FA particle size on the alkali thermal activation (ATA) and on the mechanical properties and microstructure of geopolymers was investigated. FA of different particle sizes were treated with ATA to increase the content of reactive silicon and aluminum, and geopolymers were prepared at room temperature. Results show that a vitreous of FA particles are quickly dissolved when attacked by the alkaline solution at an early age, which leads to the asynchronous dissolution of silica and alumina. Compared with the raw FA, the compressive strength of the geopolymer prepared by the finest particle FA after ATA is obviously improved from 30.51 MPa to 38.46 MPa. ATA of fine-grained FA promotes the transformation of vitreous and mullite to silicates and aluminates, which facilitates the formation of gels. The geopolymerization process of FA can be simplified into four stages. And the progress of the reactions is mainly controlled by dissolution in the early stage, while when the particle surface is covered with precipitates, the reaction is mainly controlled by diffusion. © 2022, The Authors.

A large amount of solid waste is generated during the stone processing, and a series environmental issues has arisen from the accumulated these wastes. In this work, granite powder and waste marble are used to prepare architectural glass-ceramic. The mechanical properties, microstructure and acid resistance of glass-ceramics designed with different compositions were investigated. With the increase of waste marble content, the main crystalline phase of glass-ceramic changed from anorthite to wollastonite, and the flexural strength of glass-ceramic was also enhanced. When the mass ratio of granite powder to waste marble is 40:60, a CaO-Al2O3-SiO2 (CAS) glass-ceramic with a flexural strength of 109.33 MPa and a Vickers hardness of 6.61 GPa is obtained. After the addition of MgO, the main crystalline phase of the glass-ceramic is augite. Under the addition of 5 wt% MgO, the flexural strength and Vickers hardness of CaO-MgO-Al2O3-SiOv2 (CMAS) glass-ceramic reached the maximum, which are 146.95 MPa and 10.24 GPa, respectively. The mechanical properties of these two types glass-ceramics developed from granite powder and waste marble can meet the requirements of building materials. From the acid resistance test results, the higher the content of MgO and CaO in the chemical composition of glass-ceramic, the worse the acid resistance. Therefore, the basic oxide content should be carefully controlled in the composition design of glass-ceramic. This technology of converting granite powder and waste marble into value-added glass-ceramic provides a promising method for the utilization of solid waste from stone processing, which can greatly improve the sustainability of the stone industry. © 2022, The Authors.

The recovery of vanadium from the sulfate leaching solution is crucial for resource sustainability and environmental protection. But the leaching solution contains impurities like Fe(III), which have a significant impact on the separation and enrichment of vanadium because a) separation of Fe(III) and V(IV) by solvent extraction is problematic b) when oxygen from the air is present, it is challenging to fully decrease Fe(III) to Fe(II). Citric acid was used as a complexing agent in the aqueous phase to complex the Fe(III), and the effect of extraction of V(IV) by P507 after complexation of Fe(III) with citric acid was investigated. To determine the complexation dose necessary for full Fe(III) complexation, the number of ligands in citric acid and Fe(III) complexes were estimated and the complexation mechanism of citric acid with Fe(III) was further clarified with UV-Vis and FT-IR. According to experimental findings, citric acid exhibited a better complexing action than other complexing agents. Citric acid may complex>96% of Fe(III) in liquid phase when the molar ratio of citric acid to Fe(III) was 1.5. When the pH was 1.2 and the molar ratio of citric acid to Fe(III) was 2 of the solution, the extraction rate of V(IV) was more than 80% and of Fe(III) was less than 1% by P507 while the maximum separation factor βV/Fe was 430, which achieved the complete removal of Fe(III). © 2023, The Authors.

In this paper, the influences of efflorescence on the property of alkali-activated steel slag materials were investigated, and the (Spent Fluid Cracking Catalytic) SFCC catalyst was used as an additive to control efflorescence. The property and microstructure of alkali activated cementitious materials synthesized with different raw materials composition was characterized by XRD, FTIR, TG and SEM-EDS. The efflorescence degree of different products was also evaluated. The C-S-H was mainly formed during the alkali-activated steel slag, which is difficult to adsorb the alkali metal ions, resulting in the serious efflorescence and a reduction of compressive strength. As the addition of SFCC catalyst increased, more N-A-S-H gels formed and adsorbed alkali metal ions, while inhibiting the efflorescence and its effect on mechanical property. In addition, the [AlO 4 ] - contained in the N(C)-A-S-H exhibit stronger adsorption properties for calcium ions than for sodium ions. This study not only proposed a new method of synergistic utilization of steel slag and waste SFCC catalyst, but also provided a further understanding of efflorescence. © 2022, The Authors.
