MXene在染料废水处理中的应用

Application of MXene in dye wastewater treatment

染料废水具有成分复杂、色度深、危害大等特点,染料废水的处理问题逐渐引起人们的广泛关注。MXene因其特殊的片层结构、较高的比表面积、优异的表面亲水性和丰富的活性位点使其在染料废水处理领域具有很好的应用前景,近年来得到了人们的广泛研究。对MXene的结构、组成、来源进行了简要介绍,并介绍了MXene在染料废水处理领域的研究进展,主要包括MXene直接用作染料废水的吸附剂和MXene复合材料用作吸附剂。还对MXene及复合材料在染料废水处理领域的应用前景做了展望,并提出解决MXene在吸附过程中的团聚问题是提高其对染料分子吸附能力的关键。

Treatment of dye wastewater has attracted extensive attention because of its complex composition,deep chroma,great harm,et al.MXene has been widely studied in the field of dye wastewater treatment in recent years due to its special lamellar structure,high specific surface area,excellent hydrophilicity and abundant active sites.The structure,composition and history of MXene were briefly introduced,and focused on the research progress of MXene in the field of dye wastewater treatment.MXene can be directly used as an adsorbent to adsorb dye molecules,or prepared as composite materials to adsorb dye molecules.Furthremmore,the current challenges and future research directions were also presented in terms of the application of MXene in dye wastewater treatment.It was pointed out that solving the agglomeration of MXene in the adsorption process were the key to improve the adsorption capacity of MXene to dye molecules.
