COMPARISON OF THE EFFICIENCY OF DIFFERENT NATURAL ADSORBERS IN ABSORPTION OF AS(V) AT DIFFERENT PH ENVIRONMENTS

In this work, the efficiency of various natural adsorbents for the adsorption of arsenic ion As(V) from water was studied at different pH environments. Four different natural adsorbents were used in the study and each was tested at three different pH conditions (5, 6 and 7). The results are presented in a table.本研究针对不同pH环境下，各类天然吸附剂对水中五价砷离子(As(V))的吸附效能展开探究。本研究共选用四种天然吸附剂，每种均在pH为5、6、7三种条件下开展吸附测试，相关研究结果以表格形式呈现。
