摘要
研究了2-(5-硝基-2-吡啶偶氮)-5-二甲氨基苯甲酸(5-NO_2-PAMB)与 Pd(Ⅲ)的配位反应.在 pH5.5的乙酸-乙酸钠介质中,5-NO_2-PAMB 与 Pd(Ⅱ)的配合物的吸收峰位于670nm,摩尔吸光系数为9.04×10~4L/mol·cm.方法用于钯催化剂和阳极泥样品中钯的测定,结果满意。
This paper studied the complexation reaction of Pd(Ⅱ)with 5-NO_2-PAMB.The spectrophotometyje de-termination of Pd(Ⅱ)-5-NO_2-PAMB complex in acetatebuffer solution(pH5.5)is also reported.The maxi-mum absorption wavelength of Pd(Ⅱ)-5-NO_2-PAMBcomplex is 670nm,and the molar absorptivity is 9.04×10~4L·mol^(-1)·cm^(-1).Using 5-NO_2-PAMB to deter-mine Pd in palladium catalyst and anode slime by spec-trophotometric method,satisfactory results were ob-tained.
