有机分析试剂的蓬勃发展和螯合滴定法的创立被誊为本世纪分析化学的两项最突出的成就。这是国际性权威刊物Talanta编辑部广泛征求各国分析化学家的意见后得出的结论。因此,分析试剂的研究是分析化学进展的主要标志。近年来涌现的金属分析试剂甚多,现择两种极富生命力的分述如下 The thriving development of organic reagents and the establishment of chelation titrations have been two of the most prominent achievements of analytical chemistry in this century. This is the conclusion reached by the editorial department of Talanta, an international authoritative publication, after extensively soliciting the opinions of analytical chemists from various countries. Therefore, the analysis of reagents is the main indicator to analyze the progress of chemistry. In recent years there are many metal analysis reagents, now choose two very dynamic points are as follows
