(00908)Bio-Based Phosphate Functionalized Activated Carbon from Indian Gooseberry Seed Shells for the Efficient Copper (II)Adsorption

摘要

Preparation of an efficient activated carbon for the removal of metal pollutants is a challenging research today. The characteristic features of an efficient phosphate functionalized activated carbon, synthesized by following chemical activation process followed by subsequent functionalization from Indian gooseberry seed shells for the copper (II)adsorption are reported. Indian gooseberry seed shells based activated carbon showed the BET surface area of 1359 m2/g, the adsorption capacity of 44.84 mg/g at 30 °C and at a pH value of 9.52. The adsorption process was satisfied by the pseudo-second-order kinetic model along with the Langmuir adsorption isotherm. This AC could be used as a favorable and cost-effective copper (II)adsorbent in wastewater treatment to remove the metal contaminants.
