硫铁矿中铜的测定一般采用铜试剂,铜试剂铝及新亚铜灵等比色法,这些方法操作手续比较复杂,灵敏度及准确度都较差,同时试剂毒性较大。为此,我们参考了有关资料,采用双环已酮草酰二腙(BCO)比色法测定硫铁矿中的铜。试验证明,该法简便快速,测定范围宽,同时不必分离干扰元素。 The determination of copper in pyrite generally uses copper reagent, copper reagent aluminum and neocuproine and other colorimetric method, these procedures are more complex procedures, the sensitivity and accuracy are poor, at the same time reagent toxicity. To this end, we have referred to the relevant data, using biscyclohexanone dihydrazone (BCO) colorimetric determination of pyrite in copper. Tests show that the method is simple and fast, wide measuring range, without having to separate the interference elements.
