Extraction of trace arsenic from neutral aqueous solutions with anion-exchange resins

摘要

A procedure was developed for the preconcentration of trace amounts of arsenic from almost neutral aqueous solutions with AV-16GS and AN-2FN anion-exchange resins. The recovery of arsenic from solutions with arsenic concentration ranged from 10 to 150 #mu#g/L (0.3-5 MPC of As in water) was 90-95%.
