Development of adsorbents for selenium and arsenic, which are particularly toxic, is urgently needed. arsenic was prepared for adsorption and removal. The experimental data of adsorption isotherms of As and Se oxyanions by NiZn adsorbents were well fitted to the Langmuir adsorption model, which is characteristic of monolayer adsorption, with a coefficient of determination of R2>0.94. The maximum adsorption (qmax) of Se(IV) by NiZn-Cl and NiZn-NO3 was similar to that of NiZn-AcO, and no difference in adsorption due to interlayer ions was indicated. On the other hand, NiZn-Cl had the highest qmax for Se(VI) and As(V). qmax for As(V) by NiZn-Cl was about twice that of NiZn-AcO, As(V) and Se(VI) adsorption performance was greatly improved.
