Microscale Experiments on Ion Exchangers

摘要

Laboratory experiments on ion exchangers are not popular in Japanese high schools and colleges. It may be because the experiments are time consuming. As the importance of ion exchangers in modern technology is increasing, the experiments on ion exchangers are indispensable. We have developed various laboratory experiments using tiny columns of SP- and QAE-Sephadex which are cation and anion exchangers, respectively. The column size is only about 1 cm in diameter and 3 cm in height.
