Abstract:Avocado seeds are one of the wastes generated from restaurants that serve avocado juice. This avocado seed waste can be used as activated charcoal by carbonization at high temperatures and chemical activation using HCl and H2SO4 activators. The results showed that the optimum concentration of HCl and H2SO4 activator was 5%, which at a concentration of 5% produced the smallest water content values, namely 0.5825% and 0.6763%, the lowest ash content was 0.2993% and 0.2296%, while the adsorption to iodine amounte… Show more
