The effect of impregnation ratio on the yield of corn cob activated carbon by chemical activation / Madhiyah Yahaya Bermakai and Sara Aina Afandi

Agricultural waste biomass as a precursor for the synthesis of activated carbons has increased in recent years. In spite of transportation cost, agricultural waste biomass is one of an environmentally friendly, readily available and known as renewable sources compared to conventional activated carbo...
