摘要
本文系统研究了钯（Ⅱ）与1-亚硝基-2-萘酚显色体系在石蜡相中的显色反应。在pH=0．6－11．0范围内，石蜡能定量吸附此显色络合物。采用等吸收点双被长光度法测量固相吸光度差值，把的含量在0－1．4mg/L范围内符合比尔定律，从而建立了钯的石蜡相光度分析法。方法应用于钯分子筛中痕量钯的测定，结果满意。
The colour reaction of palladium and 1-nitroso-2-napthol in paraffin phase has been studied.The complex can be quantitatively absorbed in paraffin phase at pH 0.6 to pH 11.0. The absorbance of the solid phase was measured hy using dual wavelength specrophotometry. Beer's law is obeyed in the range of 0 ~ 1.4 mg/L of palladium. The method has been appied to the determination of pelladium in palladium molecular sieve with satisfactory results.
