Article Preview

Based on cationic exchange and adsorption properties of industrial vermiculites, acid-activation processing and decoloration rate testing for industrial raw vermiculite samples industrial vermiculite samples from the Yuli Mine in Xinjiang Uygur Autonomous Region were researched. Some factors that influenced the acid-activated products adsorption and the decolorization performance were investigated, such as acid concentration, activation time, activation temperature etc., and optimum process conditions were developed as follows: the acid concentration was 3.0 mol/L, the activation time was 3 h and the activation temperature was 90°C, under these conditions, the decoloration rate of acid-activated sample was 88.46%.
