	%X This study focused on arsenate removal by nano
zero-valent iron (NZVI) in the gas-bubbled aqueous solution. It
appears that solution acidified by H2SO4 is far more favorable than by
CO2-bubbled acidification. In addition, as dissolved oxygen was
stripped out of solution by N2 gas bubbling, the arsenate removal
dropped significantly. To take advantages of common practice of
carbonation and oxic condition, pretreatment of CO2 and air bubbling
in sequence are recommended for a better removal of arsenate.
