【Abstract】 This paper discusses how to use the Gold Electrode Anode Stripping Voltammetry for measuring Micro-Arsenic in the food, and offers the method for separating the disturbing ions by reducing and distilling and collecting arsenic(Ⅲ) in standstill solution. It has been proved that the reproducibility of the data obtained-by the Gold Electrode is in the range of measurement from 25 to 400 ppb. A satisfactory result has been achieved by using the method for analysing the Micro-Arsenic in water, beverage, plant oil, as well as river products.更多还原
