Impact of pH. The pH of the water also has a strong effect on adsorption efficiency. As pH changes, the charge associated with the arsenic anion also changes. The H 2 AsO 4- anion carries a single negative charge at or below pH 7, but it loses a proton at higher pH, resulting in a doubly charged anion, HAsO 4-2.
