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...

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 presence of an additional reducing agent in the impregnation solution indicates a greater uniformity of distribution of iodide as the impregnation agent on the internat surface of activated carbon. The methylene blue decolourising power was also decreased inversely with the weight of sample.
