Abstract
A method for determination of phosphate in water samples by using flow injection spectrophotometry and modification the preparation of ascorbic acid was described in this paper.Moreover,effects of concentration of reagents and other condition had been optimized.A detection limit of 0.01mg·L~(-1) was achieved at a sampling frequency of 72·h~(-1).The relative standard deviation was 0.9% for the determination of 0.5mg·L~(-1)(n=11).The proposed method was successfully applied to the analyses of several wastewaters.
