Abstract

In this chapter, the surface modification of a natural bentonite was performed with surfactants of different ionic nature: HDTMA and TX100 as cationic surfactant and nonionic surfactant, respectively. The results show the successful modification of sodium bentonite with an ionic surfactant and a non-ionic surfactant. It was observed that the modification of bentonite with HDTMA and TX-100 was carried out by different mechanisms. HDTMA on the external surface causes the decreasing in surface area and changes in surface charge. In the case of the clay modified with Triton X-100, surface changes were small. Despite this, it verified the existence of TX-100 in the outer area of the bentonite.
