REMOVAL OF RED F3B DYE BY ADSORPTION WITH ZINC OXIDE NANOPARTICLE

This investigation comprises of the effect of various process parameters like contact time, pH, adsorption dosage and initial concentration of Red F3B dye. The maximum of 85% dye removal is achieved after 100min. of equilibrium time at optimum conditions of pH 6, adsorbent dosage 4g/L and initial dye concentration 20mg/L. Suitability of standard adsorption isotherm models - Langmuir, Freundlich and Temkin models are studied.
