硫代米蚩酮(TMK)是贵金属离子的高灵敏显色剂,与铜的显色反应亦有资料报道。我们在此基础上,研究了在 OP—10乳化剂存在下,Cu(Ⅰ)与 TMK 的显色反应并建立了测定铝合金中微量铜的方法。在测定条
Thiomyl Michler’s ketone (TMK) is a highly sensitive reagent for noble metal ions. The color reaction with copper is also reported. On this basis, we studied the color reaction between Cu (Ⅰ) and TMK in the presence of OP-10 emulsifier and established a method for the determination of trace copper in aluminum alloy.
