What is Modified aluminosilicates as low-cost sorbents of As(III) from anoxic groundwater about?
The utilization of low-grade clay materials as selective sorbents represents one of the most effective possibilities of As removal from contaminated water reservoirs. The simple pre-treatment of these materials with Fe (Al, Mn) salts can significantly improve their sorption affinity to As oxyanions. The natural kaolin calcined at 550 • C (mostly metakaolin) and raw bentonite (mostly montmorillonite) pre-treated with Fe II , Fe III , Al III and Mn II salts were used to remove of As from the model anoxic groundwater with As III concentration about 0.5 and 10 mg L -1 . All the pre-treating methods were appropriate for bentonite; the efficiency of As III sorption varied from 92 to >99%, by the sorption capacity higher than 4.5 mg g -1 . In the case of metakaolin, Fe II -and Mn II -treatments proved the high sorption efficiency (>97%), while only <50% of As was removed after Fe III and Al III pre-treatment. The sorption capacities of treated metakaolin ranged from 0.1 to 2.0 mg g -1 .
