On-line removal of sulfide interference in phosphate determination by flow injection analysis
Simple on-line sulfide removal using potassium permanganate (KMnO 4) was incorporated into a spectrophotometric flow injection (FI) system for phosphate determination using molybdenum blue with ascorbic acid as the reductant. Excess KMnO 4 was reduced before the sample zone passed through the detect...
