摘要
用溴化十六烷基吡啶代替进口试剂作活性物质,并采用不同的电极结构形式,研制成对CAS检测灵敏度更高的CAS指示电极,将其应用于Fe(Ⅲ),Al(Ⅲ)离子二元体系的电位连续滴定,获得满意的结果。Fe(Ⅲ),Al(Ⅲ)离子的回收率分别为98.9%和101%。
In this thesis Hxadecyl Pyridine Ammonium Bromide was used as the active material, and a new structure form of electrode was prepared and tested. Parameters of electrode property were measured with satisfying results were obtained. Two ion systems containing Fe(Ⅲ) and AI(Ⅲ) were satisfactorily titrated continuously with the indicator electrode.
