摘要
研究了苯异硫脲基乙酸 (PTHA)用于Pd (Ⅱ )的萃取分离性能 ,包括萃取酸度、试剂用量、萃取容量、离子干扰等方面。ICP_AES测定的结果表明 :Al3 +,Pb2 +,Zn2 +,Cd2 +,Ni2 +,Ca2 +,Mg2 +,Cr3 +,Co2 +,Cu2 +,Fe3 +一般贱金属离子不被萃取。红外光谱结果表明PTHA试剂中硫与Pd (Ⅱ )配位 ,斜率法求得试剂过量时Pd与PTHA的摩尔比为 1∶4。
Phenylthiohydantoic acid (PTHA) is prepared and the extraction separation of palladium is studied. The optimum conditions of extraction and reextraction of Pd(Ⅱ) have been investigated. The results of ICP-AES showed that the common metal ions are not extracted. This method can be used to seperate palladium from common metals with good selectivity.
