摘要：

Antimony trioxide is a very useful industrial product. There is a method of GB1467-78 to determine the impure Arsenic in it. It's very difficult to extract many times. We know that the large amount of Antimony interferes with the determination of Arsenic very seriously. Because of the different decomposition rate between hydrogen arsenide and antimonous hydride in the solution of KMn04, we can let the products of hydrogen arsenide and antimonous hydride pass through the solution of KMn04 to eliminate the antimony's interference mostly. This method is very fast and easy.
