摘要
提出了用N,N-二壬基氨基乙酸(代号DNG)从含大量贱金属离子及无机阴离子的金还原母液中萃取回收铂和钯的方法.还原母液经预处理,一次萃取、三次反萃后还原,得到海绵铂和钯的纯度为99.97％,收率为93.3％—100％.该法具有工业应用的前景.
A method of extraction and recovery of Pt and Pd is suggessed here with N,N-dinonylglycine (DNG) from the mother-liquor of reduced gold which contains a large amount of base metal cations and inorganic anions. The mother-liquor is pretreated first. Pt and Pd is extracted once and back extracted three times, and then reduced. The purity of sponge Pt-Pd is 99.97%. The recovery rate is 93.3 %-100%. This method has its using prospect in industry.
