Abstract:
An inorganic material for removing a harmful substance from wastewater is provided. The inorganic material includes a plurality of porous silicate particles having a glass phase structure, wherein the plurality of porous silicate particles include silicon dioxide, aluminum oxide, barium oxide, cesium oxide, and boron oxide, and have a zeta potential of a negative value at pH of from 1 to 5, and wherein the average pore diameter of the porous silicate particles is in a range of from 3 to 50 nm. Moreover, a method for preparing an inorganic material for removing a harmful substance from wastewater and a method for wastewater treatment are further provided.
