摘要
在实验的基础上,提出了用草酸铵试法鉴定钙时,用N-烯丙基-N′-(对苯磺酸钠)硫脲掩蔽Ag+和Hg2+离子干扰,与传统的H2S沉淀消除的干扰的方法相比,具有操作简便、条件易控制、无污染等优点.
A method was described for the eliminating the ammonium oxalate interference of Ag+ and Hg2+ with the NallylN′(sodium pphenylsulfonate) thiourea(NaNTU) in the identification of Ca2+ using (NH4)2C2O4. Compared to the traditional methods, this method is easy,simple and good effects.
