Interlayered cross-linking and formation conditions of porous clay

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