Chromium adsorption on coir pith charcoal from tannery wastewater
نویسندگان
چکیده
Emission of high chrome tanning wastewater is catastrophic for the environment. In this work, effectiveness coir pith charcoal stated removal chromium from tannery wastewater. The yield was 2.4%. prepared characterized by Fourier transform infrared spectroscopy (FT-IR). efficiency assessed experimenting with various parameters e.g., dose, contact time, and relative pH. content in raw after treatment at filtrate 3439.2 mg/L 14.9 mg/L, individually. batch experiment optimized condition, 75 mL 4 g dose 15 min attained 99.6%. level chloride (Cl-), chemical oxygen demand (COD), biochemical (BOD) were significantly reduced 65.7%, 93.7%, 95.6%, respectively. use could be an alternative source containing wastewater.

متن کاملRemoval of Sulfate from Water and Wastewater by Surfactant- Modified Coir Pith, an Agricultural Solid ‘waste’ by Adsorption Methodology
The surface of coconut coir pith, a lignocellulosic polymer was modified with a cationic surfactant, hexadecyltrimethylammonium bromide and used as an adsorbent for the removal of sulfate from aqueous solutions. Optimum pH for maximum removal of sulfate was found to be 2.0. Adsorption has been found to be concentration dependent and follows pseudo second order kinetics. Langmuir, Freundlich and...

متن کاملRemoval of Chromium (VI) in Tannery Wastewater by Bacillus cereus
Bacillus cereus was used to remove Cr(VI) in tannery wastewater containing medium at different initial Cr(VI) concentration, temperature, pH and biomass to get better conditions. At the optimum condition, the Cr(VI) in tannery wastewater was treated by each component of the cells to detect the capacity of the components for the Cr(VI) reduction. Also, the Bacillus cereus was continuous cultured...
