Multicomponent adsorption of pentavalent As, Sb and P onto iron-coated cork granulates

The assessment of multicomponent adsorption pentavalent metalloids is important since they are often found together in groundwaters and mining runoff. For this purpose, As(V), Sb(V) P(V) onto iron-coated cork granulates was studied binary ternary systems. Data from equilibrium kinetic studies revealed that uptake these contaminants a multilayer, heterogeneous process well described by Freundlich, extended Freundlich Elovich models. Most the observed interactions competitive were related to chemical structure aqueous behaviour each anion. be most impaired least affected presence other anions. aggravation reduction adsorbed amount solution more prominent for As(V) than Sb(V). outweighed pnictogens acidic solutions, but neutral conditions or may predominate instead. sensitive electrolyte addition, namely Ca salts, which promote precipitation calcium phosphates. This work provides useful insights regarding design adequate treatment systems simultaneous metalloids.
