Pengaruh Ukuran Partikel Dan Waktu Kontak Adsorben Arang Aktif Kulit Kakao (Theobroma Cacao L.) Pada Proses Adsorpsi Dalam Larutan Ion Logam Fe2+

ABSTRACT
Water and soil are generally susceptible to environmental pollution, one of the causes of pollution is the iron compound Fe2+. If the concentration of dissolved iron in the water exceeds the limit, it will cause problems such as pipes becoming corrosive. Fe metal contamination can be handled by the adsorption process using activated charcoal as an adsorbent. Cocoa rind contains high enough cellulose, hemicellulose and lignin so that it can be used as an adsorbent. This study studied the effect of the particle size of the activated charcoal cocoa husk and contact time on the adsorption process in a solution of Fe2+ metal ions. This research method begins with the preparation of cocoa skin samples, then the activation process with 4M HCl for 24 hours. The adsorption process for activated charcoal cocoa husk uses a mass of 2 grams, particle size variations of -40/+60, -60/+80 and -80/+100 mesh and a contact time of 20; 40; 60 and 80 minutes with a stirrer speed of 200 rpm and a concentration of 10 ppm Fe2+ metal ion adsorbate. The results showed that the adsorbent of activated charcoal from cocoa shells complied with (SNI) 06-3730-1995. The highest adsorption capacity was found at a contact time of 80 minutes with a particle size of -80/+100 mesh which was 0.49 mg/g and the value of the adsorption effectiveness was 99.57%.
