Ampas Tebu Teraktivasi Naoh Dan Impregnasi Fe Sebagai Kandidat Adsorben Untuk Menyisihkan Methylene Blue Dari Larutan

The sugarcane bagasse (SC) waste is a low cost adsorbant and has been reported as a highly potential adsorbent. The waste was chemically activated by NaOH to increase its surface area and to modify its structure and pore size. The sugarcane baggase was first activated with solution of NaOH (10 g SC in 100 ml of 1 g NaOH) referred to as ATAN, which was then impregnated with different solution of Fe (5, 8 and 10 ppm) designated ATAN10:1-Fe and heated with microwave for 5 minute (ATAN10:1-Fe MW 5). The resulting product was characterized by SEM-EDX for microstructure analysis and surface morphology, FTIR for functional groups and BET for surface area. The zero point charge (pHzpc) of the adsorbent was measured to determine the surface neutral charge for the experimental condition. The activated product was used as an adsorbent for removal of methylene blue (MB), using different reaction parameters such as pH, contact time, the mass of adsorbent and the adsorbate concentration to optimize the adsorption process. The characterization results showed that the bagasse activated only with NaOH had the highest surface area (2.803 m2/g) with the functional groups of O-H, C-H, C=O, C-O and O-CH3. The maximum adsorption of MB by the adsorbent ATAN10:1-Fe 10 was 96.739% achieved with the experimental conditions : MB concentration of 20 ppm, the type of ATAN10:1-Fe 10 MW 5 adsorbent with the adsorbent concentration of 2,426 mg/g. The adsorption process was suited with the Freundlich isotherm with the highest regression value of 0.9037 found in the ATAN10:1 adsorbent.
Key words : Sugarcane bagasse, adsorption, impregnation, microwave and methylene blue.
