水合氧化铁/石英砂吸附剂的制备及性质
摘要:
用反复沉淀法和加热蒸发法制备了水合氧化铁/石英砂水处理吸附剂,用电子显微镜观察了它们的表面形态,测定了氧化铁在表面上的附着能力,研究了该吸附剂对重金属离子的吸附和脱附性质.结果表明,加热蒸发法所得样品表面形态复杂;在酸性溶液和机械振荡条件下表面氧化铁有良好附着能力;对Cd2+和Cr3+有较强的吸附性质.

Preparation and Properties of Hydrous Iron Oxide/Quartz Sand Adsorbent
Abstract:
The hydrous iron oxide/quartz sand adsorbent for water and wastewater treatment was prepared by repeat precipitation and heating vaporization. The surface morphologies of the adsorbent were observed by SEM. The binding property of iron oxide on the surface of adsorbent as well as the adsorption and desorption of metallic ions were studied. Various surface morphologies of the adsorbent were found as prepared by evaporization method. Both binding property of iron oxide on the adsorbent either in acid solution or under shaking and the adsorption effectiveness of the adsorbent to Cd2+ and Cr3+ are quite good.
