Abstract: 1) were prepared using a co-precipitation method and were then employed for simultaneous removal of arsenateThe 4Al:Fe was superior to other adsorbents for removal of arsenate and fluoride in the pH range of 5.0The adsorption capacity of the Al-Fe (hydr)oxides for arsenate and fluoride at pH 6.5±0.3 increased withor fluoride adsorbent by 4Al:Fe indicated that the adsorption of arsenate and fluoride by Al-Fe (hydrThe highest adsorption capacity for arsenate and fluoride by 4Al:Fe is mainly ascribed to its highest
