Abstract

A batch reactor is used with an aluminum anode and a stainless steel cathode to decolorize crystal violet solutions by electrocoagulation. Optimization of operating parameters showed that for initial concentrations ranging from 5 to 100 mg/L, initial pH ranging from 6.72 to 5.43, current density of 250 A/m2, conductivity of 4.27 mS/cm, and inter-electrode distance of 0.5 cm, a yield of 99.75% is achieved on reduction of color and 98.5% for reduction of chemical oxygen demand (COD).

Modeling of crystal violet elimination kinetics were tested. Results showed that homogenous second order kinetics and adsorption kinetics of pseudo second order can be applied. Various isotherms models were investigated. Freundlich isotherm gave better correlation with a coefficient of 0.989.

Variable Order Kinetic (VOK) model has been associated with Freundlich isotherm to take into account production efficiency of adsorbent over the time. Results showed through a statistical analysis that this approach provides a good correlation.
