A porous substance containing a reactive material and the related method for making the substance is provided. The method includes establishing a resin substance which is porous and inert to liquids in a vessel. The resin substance is then impregnated with finer particles of a reactive material. The reactive material is chosen such that an ionic exchange reaction will occur when a liquid to be treated is passed through the particles. After the reactive material is added to the resin substance, the resulting mixture is cured by heating or by the addition of a catalyst or a combination of both heating and a catalyst. Kernels may be formed which have a sponge-like configuration and which contain the reactive particles within the supporting resin substance. Solutions may be passed through the kernels for filtration, purification, or reactive purposes. Alternatively, the substance can be poured into a treatment vessel while still in liquid form and it is then allowed to harden in situ.
