Abstract
Artificial dyes such as methylene blue are commonly detected in textile waste. Clay can be used as an adsorbent for methylene blue in the treatment of textile waste. The addition of surfactants into the system, is often done to increase the adsorption capacity of the clay. This study discusses the effect of tetrabutyl ammonium surfactant on the adsorption capacity of pyrophyllite and montmorillonite clays in the adsorption of methylene blue. The method used is molecular dynamics simulation. The simulation at 300 K 1 bar results, show that the addition of tetrabutyl ammonium surfactant causes a 12-40% decrease in the binding of methylene blue on the pyrophyllite and montmorillonite surfaces. Therefore, the addition of tetrabutyl ammonium surfactant gave unsatisfactory results for the methylene blue-pyrophyllite and methylene blue-montmorillonite systems.
