摘要
Abstract
The simulated Cr(VI)-containing wastewater was treated by bulk liquid membrane process using trioctylamine as carrier, kerosene as diluent and NaOH solution as stripping agent. The factors affecting the Cr(VI) transfer were studied. The results show that: Under the conditions of Cr(VI) mass concentration of the influent 1 043.6 mg/L, influent pH 1.1, NaOH mass fraction of stripping phase 20%, liquid membrane phase volume 100 mL, trioctylamine mass fraction of liquid membrane phase 15% and reaction time 50 min, the Cr(VI) mass concentration of effluent is 0.5 mg/L; The Cr(VI) concentration ratio can reach 94.2% after 36 times of extraction.关键词
