| Abstract: | A study of the removal of As(V) from aqueous solution by Fe2(SO4)3 has been carried out to establish optimum parameters for the process. Optimum arsenic removal is obtained at pH = 5, and mole ratio Fe(III)/As(V) = 7. Minimum arsenate solubility is obtained from sediments precipitated at pH = 5 and Fe/As = 7…8. |
