Abstract

A water purification composition and a method of preparing the same are disclosed. The water purification composition comprising porous granules of rice husk ash- silver nanoparticles-chitosan matrix, obtained by adding rice husk ash bonded to silver nanoparticles or rice husk ash and silver nanoparticles to a chitosan gel, the chitosan gel formed by dissolving chitosan in an aqueous solution of an organic acid, such that the ratio of chitosan to rice husk ash is in a range of 3:100 to 15:100 weight by weight wherein the porous granules are obtained in a range of 0.15 mm to 1 mm.
