叶蜡石吸附材料的研究现状及发展趋势
|
Abstract:
叶蜡石是我国一种优势非金属矿物，具有熔点高、化学性质稳定、资源丰富等优点，被广泛应用于生活中的各个领域。叶蜡石晶体的层状硅酸盐结构具有天然的吸附活性，且叶蜡石具有价格低廉的优势，因此常被用于重金属离子和有机污染物的去除。本文综述了叶蜡石作为吸附材料的制备与应用方面的研究进展，通过叶蜡石的改性及基于叶蜡石的新型吸附材料的制备，重金属离子和有机污染物的去除率得到大幅提高。随着研究工作的进行，基于叶蜡石改性的新型吸附材料将被应用于更广泛的领域。
Pyrophyllite is an advantageous non-metallic mineral in China. It is widely used in various fields of life with the advantages of high melting point, stable chemical properties and abundant resources. The layered silicate structure of pyrophyllite crystals has natural adsorption activity, and pyro-phyllite is inexpensive and multifunctional. Therefore it is often used for the removal of heavy metal ions and organic pollutants. In this paper, the research progress in the preparation and application of pyrophyllite as an adsorbent material is reviewed. The removal rate of heavy metal ions and organic pollutants is greatly improved by the modification of pyrophyllite and the development of new pyrophyllite adsorbent materials. With the deepening of research work, new adsorbent materials based on modified pyrophyllite will be applied to a wider range of fields.
