A simple, rapid and ecofriendly procedure is adopted to synthesize FeNPs using green tea and black tea leaf extracts for the removal of crystal violet which is used as a coloring agent and disinfector in pesticides. Experimental data was obtained for removal of Crystal violet dye using GT-FeNP-AC and BT-FeNP-AC as adsorbent. Based on the analysis the following conclusions are made. The adsorption performance was strongly affected by parameters such as agitation time, initial dye concentration, pH, adsorbent dosage and temperature. The percentage adsorption of Crystal violet was increased with ...
A simple, rapid and ecofriendly procedure is adopted to synthesize FeNPs using green tea and black tea leaf extracts for the removal of crystal violet which is used as a coloring agent and disinfector in pesticides. Experimental data was obtained for removal of Crystal violet dye using GT-FeNP-AC and BT-FeNP-AC as adsorbent. Based on the analysis the following conclusions are made. The adsorption performance was strongly affected by parameters such as agitation time, initial dye concentration, pH, adsorbent dosage and temperature. The percentage adsorption of Crystal violet was increased with an increase in contact time, adsorbent dosage and temperature, equilibrium uptake was decreased. The plot of pH versus percentage removal of dye showed that the significant adsorption took place at pH value of 7. The percentage adsorption of Crystal violet was decreased with an increase in the initial dye concentration and dye uptake was increased substantially. Hence this indicates that this process is physisorption. The present work helped in identifying a new source of adsorbent for removal of dye from effluent waste containing low concentration of dyes. Kinetics and isotherms are studied.
