摘要
在0.1mol/LNaAc中 ,钯与亚硝基R盐形成络合物的吸附波于 -0.55V(vsSCE)处产生一个灵敏二阶导数极谱波 ,钯在10～1500μg/L范围内 ,峰高与钯的质量浓度呈线性关系 ,检出限1μg/L。方法用于工业废水样品中微量钯的测定 ,结果令人满意。
Palladium(Ⅱ) and nitroso _ R _ salt(NRS) form a complex in the solution of 0.1 mol/L NaAc(pH 7.6), and a sensitive second _ order derivative adsorptive polarographic wave was found at potential of -0.55(vs SCE). The peak height is linearly related to the mass concentration of palladium(Ⅱ) in the range of 10～1 500 μg/L. The detection limit of the method is 1 μg/L. The proposed method has been applied to the determination of trace amount of palladium(Ⅱ) in the industrial waste water and catalyst samples with satisfactory results. The characters of the complex adsorptive wave were also investigated.
