摘要
本文讨论了易水解金属离子U(Ⅳ、Ⅵ)、Fe(Ⅱ、Ⅲ)Sb(Ⅲ)、Bi(Ⅲ)、Al(Ⅲ)、Ti(Ⅳ)、Cr(Ⅲ)、Zn(Ⅱ)、Ni(Ⅱ)、Ta(Ⅴ)、Nb(Ⅴ)和磷酸盐存在下,借助掩蔽-滴定法、电位滴定法、萃取法、离子交换法以及沉淀法测定游离HCl,H_2SO_4,HNO_3,H_3PO_4和H_3BO_3。
A review is given on the determination of free acid-HCl, H_2SO_4, HNO_3,H_3PO_4 and H_3BO_3, in the presence of easily hydrolytic metal ions such as U (Ⅳ.Ⅵ), Fe (Ⅱ.Ⅲ),Sb(Ⅲ),Bi(Ⅲ),Al(Ⅲ),Ti(Ⅳ),Cr(Ⅲ),Zn(Ⅱ),Ni(Ⅱ),Ta(Ⅴ),Nb(Ⅴ) and phosphate by means of masking-titration, potentiometric titration, extraction, ion exchange and precipitation methods.
