A new method for the determination of trace nitrite by spectrophotometric after cloud point extraction was *** effects of experimental conditions such as acidity,concentration of chromogenic reagent and surfactant,equilibration temperature and time on cloud point extraction were *** the optimum conditions,a good linear relationship was obtained in the range of 4.0~200 μg/L of the nitrite(r=0.9998),the detection limits of 0.43 μg/*** recoveries fell in the range from 97.7% to 102.4% and the relative standard deviations were between 1.8% and 3.2%.This method has been applied for the determination of nitrite in real water samples with satisfactory results.
