摘要
近年来,随着我国经济的飞速发展,我国对水质要求逐渐提高,对水中重金属离子的去除更加重视。传统的吸附剂由于吸附能力有限,寻找新型的高效吸附剂已成为新型吸附材料领域的研究热点。多级孔二氧化硅材料具有不同等级尺度的孔道结构、较高的比表面积和孔体积等优点,但其对水中重金属离子的吸附效果并不明显,所以使用硅烷试剂对其改性,提高其对水中重金属离子的吸附能力,探讨一种利用改性介孔硅吸附剂处理废水中重金属离子的经济高效的方法。
In recent years, with the rapid development of China＇s economy, China＇s water quality requirements gradually increases, the removal of heavy metal ions in water more attention.Traditional adsorbents due to adsorption capacity is limited, look for new efficient adsorbent has become a new field of adsorption material of research.Multilevel pore structure of mesoporous silica materials having different levels of scale, high specific surface area and pore volume, etc., but its effect on the adsorption of heavy metal ions in water is not obvious, so their modified silane reagent to improve its adsorption capacity of heavy metal ions in water, explore a modified mesoporous silica adsorbents use treated wastewater in a cost-effective method of heavy metal ions.
