Phân tích dạng asen trong nước và trầm tích ven biển bằng kĩ thuật ghép nối sắc ký lỏng hiệu nâng cao và quang phổ hấp thụ nguyên tử

A method for determination of arsenic species in environmental samples have been studied (water and sediment of Nhatrang onshore). The analytical method used was ion-exchange liquid chromatography coupled on-line to atomic absorption pectrometry through hydride generation. It was applied to determination of As species in H3PO4+NH2OH.HCl extracts of sediments. The efficiency of this extraction procedure was studied in details. The sensibility of this investigated method allows both the analysis of As-poor samples and the dilution extracts, of As-rich ones.
