摘要
报道了２－羟基－５－仲辛基－二苯甲酮肟（Ｎ５１０）从高氯酸体系中萃取钯的机理．结果表明，钯的萃取率随ｐＨ的增大而增加，而与高氯酸根离子浓度无关．采用斜率法测得萃合物组成为Ｐｄ·Ｎ５１０．
Extraction of palladium from perchloric acid medium by 2hydroxyl5secnoctyldiphenyloxime(N510) was studied The results showed that the extraction of palladium increased with the increase of pH and was independent of concentration of perchlorate The composition of extracted species is Pd·N510 as determined by the slope method The mechanism of extracting palladium from perchloric acid medium by N510 based on UVvisspectra was proved to be chelating extraction reaction as follows: H2N510(O)+Pd2+(A)=Pd· N510(O)+2H+(A)
