title: Chitosan, nanoclay and chitosan-nanoclay composite as adsorbents for Rhodamine-6G and the resulting optical properties.
abstract: The objective of this study was to investigate the use of chitosan-clay nanocomposite (CC) as an adsorbent for Rhodamine 6G (Rh-6G). The effects of adsorbent dose, contact time, and concentration on the adsorption process were systematically studied. Isotherm models were applied to the experimental equilibrium data obtained from spectrophotometric measurements of dye adsorption. Various Kinetic models were used to describe the kinetic data and evaluate of rate constants. Rh-6G loaded adsorbents were investigated for their optical and photophysical properties.
