The effects of impregnation on porosity of activated carbon / Durizah Nur Suhaimin

The purpose of this thesis was to investigate the effects of impregnation to the porosity of activated carbon by using two techniques, i.e., spray and immersion method. The process was performed by impregnating coconut shell-based activated carbon with potassium iodide solution and an additional red...
