DETERMINATION OF ARSENIC (III) BY DIFFERENTIAL PULSE POLAROGRAPHY IN THE WATERS OF CAMARONES AREA, CHILE

As (III) was determined by differential pulse polarography (DPP) in 1 mol L-1 HCl as supporting electrolyte. For quantification, the -0.35 V peak (versus Ag/ AgCl) was chosen. The obtained detection and quantification limits were 2.7 (3 SD) and 8.9 (10 SD) μg L-1 respectively. The method wa...
