dc.description.abstractThe numerous enhancements in the properties of polymer montmorillonite nanocomposites make them very significant in research and eco-friendly applications. In this study, melt blending technique was used to elaborate nanocomposites films based on high density polyethylene (HDPE) and montmorillonites (bentonite, purified-montmorillonite and Na-montmorillonite). Initially, virgin Na-MMT was obtained by cation exchange technique of purified montmorillonite, and then the nanocomposites films were produced with a montmorillonite loading rate of 4%. the prepared nanocomposites were characterized by melt flow index, density, optical microscopy and Fourier transform infrared spectroscopy. In addition, the efficiency of HDPE/MMT‟s nanocomposites in malachite green adsorption was assessed spectroscopically. The adsorption data were analysed using different isotherm and kinetic models to educate the adsorption mechanism. The experimental results obtained in this present work indicate that the HDPE/Na-MMT has good adsorption performance. The Langmuir isotherm model described better the adsorption behaviour suggesting monolayer adsorption onto homogeneous surface. Kinetic studies revealed that the adsorption process followed pseudo-second-order model, indicating chemisorption as the governing mechanism
