Study on Processing Technology of Brewer's Grains on Acid Dye Brilliant Cresyl Blue Wastewater

Abstract:

Orthogonal experiment optimization of adsorption conditions with the factors of pH value, adsorption time, adsorbent amount of brilliant cresyl blue wastewater by brewer's grains were studied. The results showed that optimum adsorption conditions were as follows: 100 mL brilliant cresyl blue dye solution of 150 mg·L^-1,adding 5.0 g·L^-1brewer's grains of 60~80 mesh and adsorbed for 2.0 h,extraction temperature 30°C,pH 5.0. Under the optimal conditions, the maximal absorption rate got 95.12%.The brewer's grains is a promising, cheap, efficient, new biological materials of adsorption for brilliant cresyl blue in wastewater.
