Liquid-Phase Polymer-Based Retention (Lpr)-A New Method for Selective Ion Separation

A new method based on the retention of ions by hydrophilic polymer reagents in a membrane filtration system, called Liquid-Phase Polymer-Based Retention, is described for selective ion separation. The principle and fundamentals of the method including the use of polychelatogens are explained and discussed. The effect of several polychelatogens on ion separation is documented and described by numerous retention profiles. It is shown that LPR is a convenient and effective method for selective ion separation of metal ions and anions.
