Polymer composite materials are disclosed containing one or more chemical scavengers. The polymer composites are porous and are configured to be contacted with a liquid for removing trace amounts of metals, proteins, polypeptides, polyphenols, other organic compounds, and the like. In order to produce the porous composite polymer product, one or more chemical scavengers are combined with high density polyethylene particles and sintered into a shape. The polyethylene resin acts as a binder trapping or encasing the one or more chemical scavengers in the porous structure.
