【摘要】 提出了一种测定工业废水中微量金铂钯的方法。方法利用脱氢双硫腙和双流腙硫上烷基加成产物（分别简称为ＴＤ—２和Ｄ—２）的氯仿溶液对微量金铂钯很强的选择萃取及富集能力，将这些金属离子从大量基体中分离富集，然后通过直流等离子体发射光谱法（ＤＣＰ—ＡＥＳ）测定．详细研究了分离富集的条件以及基体元素对贵金属萃取的影响。更多还原

【Abstract】 A procedure for the determination of gold,platinum,palladium in industrial waste water isdescribed.The method is based on extraction separation of precious metals from major matrixconstituents by means of S-alkyl derivatives of dehydrodithizone and of dithizone(TD-2/D-2)mixture.Preconcentrated An,Pt and Pd are finally quantified with ad.c.plasmaemission spectrometer.The effect of matrix on the recovery of precious metals as well as thecondition of separation and preconcentration are investigated in detail.更多还原
