Competitive Adsorption on Diatomaceous Earth Particles

Abstract
Diatomaceous earth (DE) was modified with octadecyltrimethoxysilane (C18-TMS) in the presence of p-toluenesulfonic acid (PTSA) as an acid catalyst. However, in the presence of a non-volitile acid catalyst, the determination of the adsorbed amount of the C18-TMS is complicated. Silanol groups on DE allowed the sulfonate groups on PTSA to attach to the surfaces and these surface-adsorbed acid groups stayed on the surfaces until higher...
