Orthogonal Investigation of Influencing Factors on the Modification of Montmorillonite by THPC in Acid Conditions

Abstract:

Na-MMT was modified with quaternary phosphonium salts, tetramethylolphosphonium chloride (THPC), via ion-exchange reactions, in acid conditions. Different factors such as reaction time , reaction temperature, the types of solvent, and CEC ratios, were investigated using orthogonal test. Results showed that the best combination of these four factors were A₁B₃C₁D₁, that is, the type of the solvent was acetone and water (1:1), reaction time was 3h, CEC ratio was 1:1, and the reaction temperature was 80°C.
