Biosorption of Copper II Ions by Eclipta Alba Leaf Powder from Aqueous Solutions

The removal of heavy metals from industrial wastewater is of great concern as heavy metals are non biodegradable, toxic elements that cause serious health problems if disposed of in the surrounding environment. The present study, Karisalangkani Eclipta Alba leaves were used for the adsorption of heavy metals like copper Cu II ions. The bio sorbent was characterized using SEM and BET analysis. The bio sorption experiments are conducted through batch system. The operating parameters studied were initial metal ion concentration, adsorbent dosage, initial solution pH, contact time and effect of temperature Adsorption equilibrium is achieved in 30 min and the adsorption kinetics of Cu II is found to follow a pseudo second order kinetic model. Equilibrium data for Cu II adsorption are fitted well by Langmuir isotherm model. The maximum adsorption capacity for Cu II ions is estimated to be 9.2 mg g at 25 °C. The experimental result shows that the materials have good potential to remove heavy metals from effluent and good potential as an alternate low cost adsorbent. Due to their outstanding adsorption capacities, Eclipta Alba is excellent sorbents for the removal of copper II ions. B. Kavitha | R.
