The utilization of activated carbon from cassava stems on the glucose and cholesterol adsorption

Abstract

Abstract The utilization of cassava stems from waste as an activated carbon raw material for glucose and cholesterol adsorption has been investigated. This study aims to know about the application of activated carbon from cassava stems waste on glucose and cholesterol adsorption with the variations of adsorbent weight and reaction contact time. The process of carbon acquiring was done by the pyrolysis method at a temperature of 400°C for 4 hours. After that, the process was followed by the chemical activation process using KOH as an activator. The carbon obtained was washed in KOH solution with a ratio of 1:2 w/w for ±24 hours, then filtered, washed again, and heated with an activation reactor at a temperature of 800°C. The application of activated carbon was carried out on glucose and cholesterol adsorption to produce glucose and cholesterol adsorption of 3.33 mg/g and 6.84 mg/g respectively. The optimum contact time for glucose and cholesterol adsorption was 45 minutes with the use of 0.1 g adsorbent.
