Abstract:To realize high efficiency stripping of arsenic in arsenic-bearing dust alkali leaching solution by solvent extraction method, stripping performance of stripping agent of 4%H2O2+saturated Na2CO3 was explored. The results show that more than 99% arsenic in organic phase can be stripped by 4%H2O2+saturated Na2CO3 solution under the conditions including 25 ℃, O/A=1, and contact time of 7 min. Regenerated organic phase with good cycle extraction performance can be directly used, which is helpful to realize low-cost and high-efficiency short-flow production of arsenic in alkaline solution extraction of quaternary ammonium salt.
