| 摘 要： | 在ｐＨ３．３的ＨＡＣ－ＮａＡＣ缓冲介质中，金、钯、铊分别与硫代米Ｃｈｉ酮（ＴＭＫ）形成有色配合物，在吐温－８０存在下，不但实现水相显色，而且提高了灵敏度。利用分光光度法多波长测定和反推最小二乘法，建立了金、钯、铊三组分同时测定的方法。检出限为：１０ｎｇＡｕ／ｍＬ；４ｎｇＰｄ／ｍＬ，３０ｎｇＴｌ／ｍＬ。

| Abstract: | Defferent coloured complexs were formed when TMK reacted with gold ,palladium and thallium in a medium of HAcNaAc(pH=33)and Tween80.A spectrophotometric simultaneous determination of gold,palladium and thallium has been established by 5 points of wavelength and least square method.The detection limits of gold ,palladium and thallium are 10ng/mL,4ng/mL and 20ng /mL respectively. |
