The results show that the oxidation process of arsenopyrite is speeded up with increasing concentration of FeCl3solution and rising temperature of reaction within the temperature range of 15~35℃, whereas the reaction rate of arsenopyrite is reduced at 45℃, and that the arsenic released from the reaction of arsenopyrite with FeCl3acidic solutions whose concentration is lower than 1×10-4mol·kg-1is in the form of As, which is likely to be soon oxidized into As in the FeCl3acidic solution.

结果显示：在温度为 15~35℃内，毒砂的氧化随FeCl3溶液浓度增加和反应温度升高而加速，而45℃时毒砂的反应速率反而降低；毒砂在与氧化剂FeCl3酸性溶液(浓度小于1×10-4mol·kg-1)反应时释放到溶液中的砷为As，As在FeCl3酸性溶液中很快被氧化成As。
