Interlayered Cross-linking and Formation Conditions of Porous Clay

The interlayered cross-linking of a 2:1 type montmorillonites with a hydroxy-polymers Al wasstudied by means of XRD and IR. The formation conditions and preparation process of porousclay were also dealt with. The results show that the preparation conditions such as concentrationsof cross-linking agent, reaction temperatures and washing greatly effect the formation of porousclay. The dilute solution of cross-linking agent is beneficial to the formation of porous clay; andthe process of cross-linking is reversible.
