    摘要: Water purification media contain an activated carbon having at least one of specific a particle size, surface area, and porosity; and a microcrystalline and/or amorphous titanosilicate at least partially coating the activated carbon. Methods of making the media of microcrystalline and/or amorphous titanosilicate coated activated carbon involve contacting activated carbon with titanosilicate precursors. Methods of purifying water involve contacting water containing both heavy metals and volatile byproducts with the media.
