Using modified Nano particles for removal of Crystal violet

Modified magnetite nano particles was evaluated for removal of Crystal violet(CV) of solution. Batch experiments have been performed as a function of pH, contact time, dose of sorbent, initial dye concentration, strength ionic and temperature. The experiments showed that the adsorption process was quick and the equilibrium attained within 30 min. Evaluation using Langmuir Freundlich gave sorption capacity 55.55 mg g-1. Dye uptake by new adsorbent was best described by pseudo-second order model. Using the equilibrium concentration constants obtained at different temperatures, various thermodynamic parameters have been calculated. The results indicated that dye adsorption was feasible, spontaneous, and endothermic.
