摘要： A method for the removal of soluble metal ion contamination from fluids is disclosed. The method includes passing the contaminated fluid through a filter medium comprising a reducing metal and a filter aid, such as diatomaceous earth, and collecting a filtrate with lower concentration of soluble metal ion contamination. The reducing metal can have a reduction potential of from −0.50 volt to −3.10 volt and can be capable of reducing the soluble metal ions to insoluble metal, which can then be entrapped in the filter medium or otherwise separated.
