马蹄皮吸附剂的制备及吸附甲基橙的性能研究

Study on the Preparation of Water Chestnut Adsorbent and Adsorption Performance of Methyl Orange

为了对二甲胺进行胺化,以马蹄皮为原料,对其进行预处理后,用环氧氯丙烷进行醚化,将制备的马蹄皮吸附剂对甲基橙进行吸附,研究吸附剂用量、p H、甲基橙初始质量浓度、反应温度等因素对马蹄皮吸附剂吸附甲基橙效果的影响,通过单因素和正交试验获得最佳吸附条件。结果表明,最佳的吸附条件为:吸附剂用量6 g/L、p H2、甲基橙质量浓度100 mg/L、反应温度30℃。在此条件下,马蹄皮吸附剂对甲基橙的吸附率达97.19%。

To amine dimethylamine,water chestnut as material,water chestnut adsorbent was prepared with epichlorohydrin after preprocessing.The effects were studied with adsorbent dosage,p H,initial concentration of methyl orange with water chestnut adsorbent and reaction temperature.The best adsorption condition was obtained with the single factor and orthogonal test.The results showed that the optimum adsorption condition was adsorbent dosage 6 g/L,p H 2,the concentration of methyl orange quality 100 mg/L,the reaction temperature 30 ℃,under such condition,water chestnut skin adsorbent adsorption rate of methyl orange was 97.19%.
