Abstract

For removing color produced by organic dyes in an effluent, a novel composite consisting of diatomaceous earth and calcium silicate hydrate gels was prepared by hydrothermal treatment. Calcium silicate hydrate gels covered the surface of alkalitreated diatomaceous earth in the form of pores during the treatment. The methylene blue adsorption capacity of the composite was greater than that of diatomaceous earth.
