SINTESIS MEMBRAN NATA DE PINA DAN APLIKASINYA UNTUK ADSORPSI ZAT WARNA TEKSTIL REMAZOL RED RB
Abstrak
This study utilized pineapple peel waste into a membrane of nata de pina and used as an adsorbent for remazol red RB. The purpose of this study was to synthesis nata de pina membranes, determine the optimum pH, concentration and contact time of adsorption, isotherm pattern, and the maximum adsorption. The results indicated that cellulose nata de pina membranes were successfully synthesized and had the potential to become adsorbents for absorbing remazol red RB dyes. FTIR results showed that membrane nata de pina was a cellulose based membrane with swelling test result of 187.9%. The optimum conditions were at pH 2 with adsorption capacity of 17.12 mg/g, concentration of 80 mg/L with absorption capacity of 22.36 mg/g and contact time at 120 minutes with absorption capacity of 25.29 mg/g. The adsorption of remazol red RB dye has fulfilled the pattern of Langmuir adsorption isotherm with maximum adsorption of 0.0219 g/g or 21.9 mg/g adsorbent.
