PROGRESS OF THE APPLICATION OF CLOUD POINT EXTRACTION TO THE SEPARATION AND ENRICHMENT OF METAL IONS AND TO THE SPECIATION ANALYSIS

A review of the progress of application of cloud point extraction (CPE) to the separation and enrich ment of metal ions and to the speciation analysis of metal ions,covering mainly the period of last decade,was presented.Basic principle,experimental procedures and the main factors affecting the extraction rate of CPE were introduced and discussed.The trend of development of CPE in the future was also given briefly (103 ref.cited).
