Abstract 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 including use polychelatogens are explained discussed. effect several separation documented numerous profiles. It shown that LPR convenient effective metal anions.
Abstract
Abstract Theoretical approaches to the description of ion retention in aqueous solution by soluble polymers during membrane filtration are proposed. Examination chemisms responsible for inorganic complexation and membrane‐based separations helps select appropriate hydrophilic optimum chemical conditions process. The separation enrichment data may be formally explained using mathematical models based on theory kinetics reactions partially open systems.
Abstract Preconcentration and recovery of arsenic from diluted aqueous solutions by soluble polymeric reagents in combination with membrane filtration were investigated. Quaternized poly(ethyleneimine) was found to be an efficient reagent for removal separation As(III), As(V), divalent metal cations such as Cu, Cd, Zn, Co. Using a 4% solution the polymer reagnet, 98% arsenic(V) retained at pH 8.5, which could stripped off addition 0.15 M sodium salt same pH. A practical application...
