Adsorbent based on silica derived from bagasse fly ash has been synthesized. The synthesis adsorbent began by performing the silica synthesis of BFA by the hydrothermal alkali method. Silica gel was characterized, FTIR spectroscopy and Surface Area Analyzer. The obtained Silica was modified with Hexadeyl Tri Methyl Ammonium Bromide (HDTMAB) at concentrations of 10, 20, and 30 mmol / L using the impregnation method. The three variations of adsorbent were applied to reduce hexavalent chromium in tannery waste water. Adsorption of chromium hexavalent were optimum at 20 mmol/L HDTMAB. The optimum adsorbent cationic was characterized using FTIR, SEM and BET spectrophotometer and applied to leather tanning waste.
