“…The extent of adsorption of anions is strongly governed by the pH of the solution [21][22][23][24]. The effects of the solution pH on arsenate removal were studied by varying the pH of the solution over a range of 3-10 using either 0.1 M HCl or 0.1 M NaOH.…”

“…Some studies have also examined the influence of pH on arsenic adsorption by soils. Pierce and Moore (1982) found that the adsorption of arsenate by amorphous iron hydroxide was substantially pH-dependent. Goldberg (2002) investigated the pH dependence of arsenic adsorption on clay from pH 2 to 10 and observed the maximum adsorption of arsenic at pH 2.…”

Citrate-dithionite extractable Fe has the most important positive influence on arsenate adsorption on soils. AbstractAn attempt has been made to elucidate the effects of soil properties on arsenate adsorption by modeling the relationships between adsorption capacity and the properties of 16 Chinese soils. The model produced was validated against three Australian and three American soils. The results showed that nearly 93.8% of the variability in arsenate adsorption on the low-energy surface could be described by citrate-dithionite extractable Fe (Fe CD ), clay content, organic matter content (OM) and dissolved organic carbon (DOC); nearly 87.6% of the variability in arsenate adsorption on the high-energy surface could be described by Fe CD , DOC and total arsenic in soils. Fe CD exhibited the most important positive influence on arsenate adsorption. Oxalate extractable Al (Al OX ), citratedithionite extractable Al (Al CD ), extractable P and soil pH appeared relatively unimportant for adsorption of arsenate by soils.

“…On the other hand, iron oxides, especially amorphous iron oxides, have also been reported to be effective for arsenic removal (Pierce and Moore, 1982;Cornell and Schwertmann, 1996;Reed et al, 2000), but the endurance and stability of the adsorbent should be improved. While the crystalline oxides of iron are stable in aquatic environment, the efficiency for arsenic removal is poor.…”
