Abstract
In this paper,cetyltrimethyl ammonium bromide was used for organic modification of Na-montmorillonite.The organically modified montmorillonite was analyzed by SEM,TG,and XRD.The results show that the cetyltrimethyl ammonium bromide has been intercalated into the layers of montmorillonite.The weight loss rate of montmorillonite is 23%,and the layer distance of the montmorillonite is increased from 1.272 nm to 2.628 nm.
