| Abstract: | A method for the determination of Arsenic in a supporting solution of saturated tartrate acid / potassioum antimony tartrate (8.0 mg/L) / Selenium (0.40 mg/L) by single sweep polarography has been established. The peak potentials is 0.87V (vs.SCE). The peak height is linearly proportional to the concentration in the range of 0.08 ~ 12.0 礸/mL;the detection limit is 0.06 g/mL for Arsenic. This method is simple,sensitive and has good selectivity. The result is satisfactory when it is used to analyze environmental water samples. |
