| Abstract: | Tobermorite is a mineral material with good ion exchange properties.The potassium feldspar ore from Lushi country is muscovite syenite.Potassium feldspar was hydrothermally decomposed with CaO as an additive,and then tobermorite nano-scale powder was synthesized.Based on the research work,the adsorption property of tobermorite to Hg2+ from aqueous solution was studied.The factors of adsorption were studied such as pH values,the reaction time,initial concentration,the temperature.By the orthorhombic experime... |
