| Abstract: | Adsorption of Cr^6＋ by non-living biomass material-corncob powder was studied. The effects of pH value, initial Cr^6＋ concentration, contact time and temperature on adsorption Were investigated. The results indicated that modified corncob powder had good adsorption to Cr^6＋. Under the condition of temperature at 33 ℃, pH at 2.0 and contact time of 120min, with 1.0 g modified corncob powder and 50 mLCr^6＋ solution which concentration is 20 mg/L, the adsorption rate of Cr^6＋ can be up to 98.16%. |
