METHOD OF REMOVING AND RECOVERING SILICA USING MODIFIED ION EXCHANGE MATERIALS

摘要

A method of preferentially removing or recovering silica from a source, including aqueous sources such as ground and potable water, which utilizes a modified ion exchange material that holds or captures the silica by ion exchange with a metal contained in the exchange material whereby the method includes the steps of: providing an ion exchange material; immobilizing a metal complex to form at least a portion of a metal containing substance inside the ionic exchange material; and contacting the source with at least a portion of the metal containing ionic exchange material.
