Preparation of activated carbon by chemical activation and its in vitro adsorption efficacy tests for paraquat

Preparation of activated carbon by chemical activation and its in vitro adsorption efficacy tests for paraquat

The effects of different activation temperature on the pore size and surface morphology of activated carbon produced by H3PO4 (30%) chemical activation were studied in this paper. Well developed pore size and highest surface area observed on activated carbon at 6000C were determined by Scanning E...
