Activated Carbon from Rice Husk for Treating Dye Waste Water

N Samson Maria Louis, Arjuman Banu, S Sudha


This study was undertaken to explore the possibility of utilizing rice husk (RH) for the production of activated carbon because of its abundant, renewable, and biodegradable raw resource, and properties such as its chemical stability, oil absorption, surface area, iodine value, and high reactivity, resulting from the presence of chemically reactive hydroxyl groups. RH is roasted at high % with low cost chemical as catalyst to reduce time, with temperature control to get high yield, certain low cost chemical are added with definite impregnation time, activation temperature, and time, contact time, pH, dose, and particle size for obtaining activated carbon for treating dye waste water containing methylene blue. The results indicate that activated carbon from RH is a good adsorbent for the removal of methylene blue from wastewater.

Keywords: RH, temperature, Si-OH groups, activated carbon, surface area, iodine value, particle size
