关于硫代米氏酮(TMK)测定金,国内不少单位作了许多有益的改进。然而多数方法均用异戊醇萃取,该试剂不但刺激味大,而且有毒。有人把试剂配在醋酸、醋酸钠、正-丁醇的混合溶液中,增强了试剂对光的稳定性,可测1—50微克/毫升金,但汞、银、钯等对金有严重干扰。我们在前人工作基础上,通过试验选择了无刺激性气味的正-丁醇代替异戊醇,在1％HCl-15％NaCl On the thiomyl ketone (TMK) determination of gold, many domestic units made many beneficial improvements. However, most methods are extracted with isoamyl alcohol, which not only stimulates the taste but also is toxic. Some reagents with acetic acid, sodium acetate, n-butanol mixed solution, enhance the stability of light reagents, measurable 1-50 micrograms / milliliter gold, but mercury, silver, palladium and other serious interference with gold . Based on the work of our predecessors, we selected n-butanol instead of isoamyl alcohol as a non-irritating odor and tested it in 1% HCl-15% NaCl
