| Abstract: | It is that strontium was firstly separated and enriched using P204-N205-Liquid paraffin-kerosene-HCl as Liquid membrance (LM) system. Running water drink and natural mineral water were concentrated and determined by FAAS method. Enrichment muitiple can reach 10 times by once extracting and separating. The recoveries was nearly 100%. |
