Power Mg(OH)(2) was used to remove As(III) from arsenic-bearing wastewater. Results showed that Mg(OH)(2) had strong adsorptive property on As(III) ions with its adsorption capacity of 4.04 mg/L; Mg(OH)(2) adsorption on As(III) fit well with Langmuir Isotherm equation; As(III) removal rate increased with vibration time and input quantity of adsorbents while decreased as pH increased and effects were obvious; temperature had little affection on arsenic adsorption; As(III) removal rate can exceeded 99% when reaching equilibrium under condition As(III) concentration of 20 mg/L, Mg(OH)(2) input qu...
