Abstract

The extraction of cellulose from pineapple (Ananas comosus) peel has been carried out through delignification using alkaline and hydrolysis with acid. The extraction of cellulose was carried out by de-waxing, delignification followed by hydrolysis with H2SO4 acid. The cellulose obtain was identified by FTIR and SEM-EDS. The results showed that the FTIR spectra of pineapple peel cellulose contain hydroxyl and carboxyl functional groups which useful in the adsorption process. The morphology of cellulose has a more homogeneous and porous shape. The cellulose obtained was used for adsorption of Remazol yellow dye by studying adsorption parameters, namely the effect of pH, contact time and solution concentration. The adsorption process was obtained at pH 2, the optimum contact time was 30 minutes and concentration at 100 mg/L with an adsorption capacity is 19.888 mg/g.

Abstract

Remazol Yellow is a dye that contains an basic amino group and a benzene core, so it is difficult to be naturally degraded by microorganisms and causes environmental pollution. One solution to reduce the dye waste polluted in waters can be done by adsorption method using pineapple peel cellulose as adsorbent. Before turning into pineapple peel cellulose, the NaOH delignification process and H2SO4 hydrolysis were carried out first. The adsorption process for rhodamine B dye was carried out on 2 parameters, namely pH, contact time and determination of the adsorption system using the Langmuir and Freundlich equations at various concentrations of 5, 10, 15, 20, 25, 50, 75 and 100 ppm. Testing the effect of pH on the adsorption of Remazol Yellow was carried out with variations in pH namely 2, 3, 4, 5, 6, 7 and 8. . The results showed the optimum conditions at pH 2, contact time of 30 minutes and the Langmuir isotherm adsorption system with an adsorption capacity of 19.888 mg/g
