Abstract:

Abstract: Surface response optimization of adsorption conditions of neutral red wastewater by brewer's grains with the factors of pH value, initial concentration,adsorption temperature, adsorption time, adsorbent quantity and the response of adsorption rate were studied. The optimal parameters for adsorption conditions were of adsorbent concentration of 191.24 mg·L-1, adsorbent particle size of 60~80 mesh,pH 4.65, adsorbent amount of 2.56 g·L-1, adsorption time and temperature of 1.92 h and 30°C, respectively. The maximal absorption rate got 99.16%.The brewer's grains is a promising, cheap, efficient, new biological materials of adsorption for neutral red in wastewater.
