Abstract
Toxicities caused by hazardous elements encountered in water is problem to be dealt with. The present work focusses on the synthesis of polymeric composite material (Adsorbent) and explores its adsorption properties towards certain heavy metal. Sol-gel was used as a method of synthesis. The polymeric material prepared is polyaniline Tin (IV) Phosphate and the emphasis was on its adsorption behavior of towards heavy metal ion. The advantages of this composite are not only its easy and rapid separation but also its selectivity towards target pollutants through its polymeric matrixes. The experimental data show that polyaniline/Sn(IV) phosphate composite has reasonable good adsorption capacities for Cu(II). Studies of adsorption are taken out via Batch method. The optimum condition for excellent removal efficiency of the material was fulfilled by altering certain framework like concentration, pH, temperature, adsorbent dose, and time. The morphology of the surface of prepared composite prior to and after Cu(II) adsorption was determined by scanning electron microscopy. EDX analysis shows the presence of C, O, S, P, and Sn but after adsorption a new peak of Cu(II) appeared indicating the Cu(II) uptake onto composite polyaniline/Sn(IV) Phosphate. It was acknowledged that uptake of Cu(II) was pH vulnerable. The result of the adsorption almost suited to the Langmuir, D-R isotherm and Freundlich framework. The kinetics data for Cu(II) adsorption were ultimately suited to pseudo-second-order framework. The mechanism was spontaneous and endothermic as ensured by the thermodynamic parameter about adsorption experiment. Thermodynamic parameter ensured about the adsorption experiment that process was endothermic and spontaneous. The composite can be utilized so that the pre-concentration including recovery of Cu(II) ions from water as well as wastewater.
