摘      要：An untried,low cost,locally available biosorbent for its anionic dye removal capacity from aqueous solution was *** prepared from peanut hull had been used for biosorption of three anionic dyes,amaranth (Am),sunset yellow (SY) and fast green FCF (FG).The effects of various experimental parameters (*** pH and dye concentration,sorbent dosage,particle size,ion strength,contact time etc.) were examined and optimal experimental conditions were *** initial pH 2.0,three dyes studied could be removed *** the dye concentration was 50 mg·L -1 ,the percentages of dyes sorbed was 95.5% in Am,91.3% in SY and 94.98% in FG,*** ratios of dyes sorbed had neared maximum values in all three dyes when sorbent dose of 5.0 g·L -1 and the sorbent particle size in 80～100 mesh was *** increasing the ion strength of solution caused the decrease in biosorption percentages of *** equilibrium values arrived at about 36 hour for all three *** isothermal data of biosorption followed the Langmuir and Freundlich *** biosorption processes conformed the pseudo-first-order rate *** results indicated that powdered peanut hull was an attractive candidate for removing anionic dyes from dye wastewater.
