PENGARUH KONSENTRASI AKTIVATOR ZnCl2 TERHADAP KUALITAS KARBON AKTIF DARI KULIT UBI KAYU UNTUK PENYERAPAN LOGAM BERAT

Abstract

Activated carbon from cassava peel has been produced using chemical activation with Zinc Cloride (ZnCl2) as activator assisted by microwave irradiation with the output power 630 watt for 20 minutes. Concentration of ZnCl2 was varied 1M, 2M and 3M. The aim of this study to is determine the morphological characteristics, microstructure, contents of elements and the adsorption of activated carbon to the metal Fe, Pb and Cu. As whole, the result of calculating and analyzing the activated carbon showed that the activator consentration influenced the quality of activated carbon. aktivated carbon with concentration of ZnCl2 3M showed the best result with adsorption of activated carbon to Fe, Pb and Cu were 70,70%, 70,90% and 69,61% respectively.
