作为一种较新的富集分离手段——螯合离子交换技术,现被人们认为在分析化学中有广泛的发展前途。近年来,已研制出近百种不同类型的螯合离子交换树脂,而其中巯基型螯合吸着剂可能具有更大的实用价值和意义。日本、美国、捷克、法国等国相继 As a new enrichment and separation method - chelating ion exchange technology, is now considered in the analytical chemistry has a wide range of development prospects. In recent years, nearly 100 kinds of chelating ion exchange resins have been developed, of which mercapto-type chelating sorbents may have more practical value and significance. Japan, the United States, the Czech Republic, France and other countries have been
