Abstract
ABSTRACT Bioadsorbent preparation from rambutan peel applied as adsorbent was characterized using FT-IR, SEM-EDS, BET and TG-DTA analysis. FTIR analysis showed the presence of specific cellulose compounds in the rambutan peel bioadsorbent, the rambutan peel bioadsorbent was amorphous, there were wavy and uneven pores in the morphology of the rambutan peel and had the highest elemental content of 74.3%, the surface area of the rambutan peel was 1.22 cm/g. The adsorption process was applied to malachite green, congo red, and procion red dyes with parameters such as pH, kinetics, isotherm and thermodynamics. Based on kinetic parameters, the adsorption process of malachite green, congo red, and procion red using rambutan peel tends to follow the pseudo second order kinetic model. The adsorption capacity achieved was 182.40 mg/g in procion red, 6.24 mg/g in congo red, and 11.73 mg/g in malachite green. The adsorption process takes place spontaneously which is indicated by a negative Gibs free energy value.
