摘要： PURPOSE: A method for removing metallic ions and particulate material from an aqueous acid solution using particle removing membranes such as ultra high molecular weight polyethylene having immobilized ligand groups that possess capacity and high equilibrium binding constants for ion removal, even in acid. The method is particularly useful for simultaneously filtering/purifying aqueous acids, such as hydrofluoric or hydrochloric acid. CONSTITUTION: The process for removing metallic ions and optionally particulate material from an aqueous acid solution comprises the steps of (i) contacting the solution with a composition suitable for removing metallic ions and optional particulate material contained in the solution; (ii) recovering a purified and filtered solution essentially depleted of metallic ions and optional particulate material, wherein the composition comprises a membrane ligand combination represented by the formula: M-B-L wherein M is a membrane or composite membrane having a hydrophilic or partially hydrophilic surface and containing polar functional groups; L is a ligand having an affinity for metallic ions and containing a functional group reactive with an activated polar group from the membrane; and B is a covalent linkage formed by the reaction between the activated polar group and the functional group of the ligand.
