APLIKASI ARANG AKTIF TONGKOL JAGUNG TERAKTIVASI CaCl2 DAN KALSINASI 500°C SEBAGAI ADSORBEN UNTUK MENINGKATKAN KUALITAS AIR GAMBUT

Abstract

This research aims to convert corncorb into charcoal through a carbonization process and activated with CaCl2, then applied to improve the quality of peat water. Carbonization was carried out with klin drum method and activated with CaCl2 1%. Then, calcined at 500°C for 40 minutes. Corn corbs activated charcoal (AATJ) was characterized by the moisture content, ash content, iodine adsorption capacity, methylene blue adsorption capacity, functional groups with FTIR and surface morphology with SEM. Based on the results, AATJ has characteristics the moisture content 1,19 %; ash content 3,03 %; iodine adsorption capacity 973,02 mg g-1, and methylene blue adsorption capacity 8,45 mg g-1. Corn corbs activated charcoal applied for peat water treatment with various dose (0,5; 1; 1,5; 2) g and various contact time (15, 30, 60, 120) minutes. The best condition of peat water adsorption was obtained at dose of 1,5 g and contact time at 60 minutes with a percentage of reduce turbidity 59,24%, Fe metal content 29,67%, TDS 71%, increased pH from 4.2 to 6.9 and has been able to remove odors on peat water.
