Surface response optimization of Adsorption Conditions of Cr (VI) wastewater by PEI modified brewer's grains (BSG) with the factors of pH value, adsorbent concentration, adsorption time, amount of adsorbent and the response of adsorption rate were studied. The optimal parameters for adsorption conditions were of adsorbent concentration of 113.30 mg/L, adsorbent particle size of 60~80 mesh, pH 1.79, adsorbent amount of 4.99 g/L, adsorption time and temperature of 1.88 h and 30°C, respectively. The maximal absorption rate got 100.0%, adsorption capacity was 46.58 mg/g. The PEI modified BSG is a promising, cheap, efficient, new biological materials of adsorption for Cr (VI) in wastewater.
Key words: Adsorption conditions, Cr (VI), modified brewer's grains (BSG), response surface methodology, , ,
