摘要
以微晶纤维素为基质 ,制备了带有 NH2 基团的纤维素 -铝 -硅复合物 ,测定了该复合物对水溶液中 Hg2 + 、Cu2 + 的吸附性能。讨论了溶液温度、p H值、金属离子浓度及时间对吸附性能的影响 ,结果表明它对Hg2 +和 Cu2 +具有较高的吸附容量和较快的吸附速度。
By reaction of microcrystalline cellulose substrate with aluminium iso-propoxide and triethoxy-aminopropylsilane, a cellulose-Al-Si composite containing amino groups was prepared. The adsorption properties of this composite for heavy metal ions were studied in aqueous solution. The effects of the temperature, pH value, metal ionic concentration of the solution and adsorption time on the adsorption capacity were discussed. The results show that the cellulose composite has high adsorption capacity and rapid rate for Hg^(2+) and Cu^(2+).
