CLERODENDRUM SERRATUM STEM ACTIVATED NANO POROUS CARBON BY ADSORPTION CHARACTERISTICS FOR REMOVING CU(II) IONS FROM WASTEWATERM. Anitha, S. Arivoli and K. VeeravelanAbstract A series of batch research studies were carried out utilizing Activated Clerodendrum serratum Carbon (ACSC) for the adsorption removal of copper (II) ions from an aqueous solution. The investigation was carried out by looking into the effects of beginning pH, contact time, adsorbent dosage, and initial copper concentration. All of the batch experiments were conducted at a steady temperature using a wrist-action shaker set to 200 rpm. Langmuir and Freundlichâs isotherms were used to examine the single-component equilibrium data. Maximum copper ion adsorption, i.e. >90%, was attained in aqueous solutions employing 0.025g of ACSC at a pH of 6.6. The copper ACSC kinetic process was modeled using a pseudo-second-order equation, the Elovich model, and intra-particle diffusion. This study found that activated ACSC has a great capability for removing Cu(II) ions from aqueous solution. The nature of adsorption was observed by analyzing various thermodynamic factors such as ïGo, ïHo, and ïSo. |
