摘　　要：研究了用十六烷基三甲基溴化铵的氯仿溶液,从氢溴酸介质中对钯的萃取。采用斜率法测得萃合物组成为CH3(CH2)15(CH3)3N·HPdBr4,萃取反应方程式为:CH3(CH2)15(CH3)3NBr(O)+HPdBr-4(A)=CH3(CH2)15(CH3)3N·HPdBr4(O)+Br-(A)。The extraction mechanism of palladium from hydrobromic acid medium with hexadecyltrimethyl ammonium bromide has been studied.The composition of extracted species is determined as CH3(CH2)15(CH3)3N·HPdBr4 by slope method.The extraction mechanism of palladium with hexadecyltrimethyl ammonium bromide was proved to be ion exchange extraction reaction as follow:CH3(CH2)15(CH3)3NBr(O)+HPdBr-4(A)=CH3(CH2)15(CH3)3N·HPdBr4(O)+Br-(A).
