摘要：

<p>A process for removing copper ions from an aqueous solution particularly an industrial effluent where the copper is in complexed form, requires the solution to be adjusted to a pH value of less than 6, preferably 2 to 4, before it is contacted with steel wool. Apparatus comprises a solution reservoir to which acid is controllably supplied to maintain the desired pH value, and one or more replaceable canisters of steel wool through which the solution is pumped from the reservoir.</p>
