Karakterisasi Asap Cair Dari Tempurung Kelapa Hasil Pemurnian Dengan Metode Adsorbsi-Desorpsi

Abstract

Liquid smoke result from condensation of combustible materials that contain lignin, cellulose, and hemicelluloses. Liquid smoke is categorized by its level of purity and the active compound such as acetic acid and phenol. The purpose of this study was to characterize the liquid smoke by adsorption and desorption method including total acid content, total phenol content, pH, and density. Different properties compound in liquid smoke obtained with variation of mass and type of zeolite. As much as 10 gram natural zeolite on adsorption fraction showed the highest acid and total phenol content, which were 9% and 13,7% respectively. The other hand of desorption fraction method with the highest acid and total phenol content was obtained by using activated natural zeolite 90 grams were 6,3% and 9,4% respectively. Activation zeolite as much as 90 grams showed the highest adsorption mass of liquid smoke thats 19,3 gram. Variation of type and mass of adsorbent did not give a significant influence to the value of density and pH of liquid smoke where the value of each ranged from 1,001-1,107 and 2,5-3 respectively. The results showed that the characteristic of adsorption fraction and desorption fraction have passed the standard quality of Japanese liquid smoke
