酿酒废弃葡萄皮渣对Cr(Ⅵ)的吸附能力研究
Adsorption of Cr(Ⅵ) in Solution by Abandoned Wine Grape Pomace
摘要
Abstract
The abandoned wine grape pomace (WGP) was used as adsorbent to remove Cr(Ⅳ) in solution. The effects of adsorption time, particle size. WGP dosage, solution pH and Cr(Ⅳ) concentration on the adsorption were discussed. It was found that adsorption balance reached at 4 h and adsorption rate of Cr(Ⅳ) by WGP was 87.97%.WGP with particle size lager than 60 mesh showed the highest adsorption capability. Positive correlation was observed between adsorption rate and WGP dosage. The adsorption rate tended to peak (above 88%) when WGP dosage was above 1 g. Asorption rate of Cr(Ⅳ) by WGP decreased with the increase of solution pH till the pH value reached 3. The higher Cr(Ⅳ) concentration, the higher adsorption rate was found. It can be concluded that WGP was a kind of effective adsorbent with strong adsorption ability to Cr(Ⅳ).关键词
