Abstract

In this study, activated biocarbon was prepared from coconut shell biocarbon by base activation using potassium hydroxide (KOH) as the dehydrating agent. The optimum preparation condition was determined by Response Surface Modelling (RSM) using Box Behnken Design (BBD). The relationship of independent factors i.e. activation temperature (T), holding time (t) and impregnation ratio (IR) was investigated towards maximum yield response, as measured through iodine value (mg/g). The optimum activation conditions were found to be temperature = 900 ºC, holding time = 15 min, and impregnation ratio = 1.75 which yielded higher iodine value (1169.19 mg/g). The correlation coefficient (R2=0.9223) obtained showed that the model is able to predict the iodine number value efficiently.
