Abstract
Adsorptive interaction of Rhodamine-B dye onto microwave assisted zinc chloride activated carbon from aqueous solution was investigated. Activated carbon was prepared from the aerial root of Ficus benghalensis L. Carbon prepared was designated as ZAC (zinc chloride activated carbon). Experiments were carried out in a batch process using various parameters such as pH, dose of the adsorbent, contact time, initial dye concentration. Kinetics of the system were studied with linearised forms of Lagergren, HO and Webber Morris model. Equilibrium data were showed with Langmuir, Freundlich, Tempkin, and Dubinin-Raduskevich isotherm equations. Implications obtained from the isotherm parameters were discussed. Thermodynamic parameters such as ΔH°, ΔS° and ΔG° were determined using Vant’t Hoff plots. The XRD and FTIR spectral analysis were defined that adsorption was physisorption.
