  • 摘要: 以盐酸和十六烷基三甲基溴化铵对包钢高炉渣进行表面改性，通过XRD、SEM和N2吸附-脱附测试研究其微观结构和孔径分布，并以阴离子型染料甲基橙溶液为模拟染料废水研究其吸附性能，进而探索最佳改性制备条件。研究结果表明：有机改性高炉渣主要化学成分为SiO2，表面有明显的孔道结构，比表面积高达394.5 m2·g-1，平均孔径为12.4 nm；有机改性高炉渣对甲基橙溶液均具有较强的吸附性能，最佳改性条件为加入改性剂盐酸浓度为3 mol·L-1、十六烷基三甲基溴化铵的最终投加浓度为8 g·L-1、水热温度160 ℃和16 h，此时所制备的有机改性高炉渣吸附性能最强，吸附率为98.06%，最大吸附量达357.14 mg·g-1。等温吸附实验表明，有机改性高炉渣对甲基橙溶液的吸附属于多分子层吸附。
    Abstract: Blast furnace slag(BFS), produced from Baotou Iron and Steel Co. Ltd., was modified with hydrochloric acid and cetyltrimethyl ammonium bromide(CTAB) to improve its surface activity. The obtained samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM) and N2 adsorption-desorption. Their adsorption, adsorption performance for methyl orange(MO) were studied to optimize the modification condition. The results showed that the main chemical compositions of organic modified BFS(OMBFS) was SiO2, and it had a clear channel structure with a surface area of 394.5 m2·g-1 and the pore size of 12.4 nm. Optimum modification conditions corresponded to hydrochloric acid concentration of was 3 mol·L-1 for the addition of modifier, CTAB concentration of 8 g·L-1, hydrothermal temperature of 160 ℃,and hydrothermal time of 16 h, achieving MO adsorption rate of 98.06％, and maximum adsorption capacity of 357.14 mg·g-1. Isothermal adsorption experiments show that the OMBFS on the adsorption of methyl orange solution belongs to the multilayer adsorption.
