Abstract

The present disclosure relates to the technical field of water purifying material, and in particular to a kaolin-based water purifying material, a preparation method and use thereof. The method for preparing a kaolin-based water purifying material provided by the present disclosure includes the following steps: mixing kaolin and a modifier with water, and conducting hydrothermal reaction to obtain a kaolin-based water purifying material; the modifier is an organic or inorganic modifier; the organic modifier is octadecyl trimethyl ammonium chloride (OTAC), and the inorganic modifier is one or more of polyaluminum chloride, Al2(SO4)3, Fe2(SO4)3, AlCl3 and FeCl3; the kaolin is 200-400 mesh in particle size. The water purifying material of the present disclosure enables efficient algae removal and water purification, and is safe and eco-friendly.
