Research progress on the adsorption of printing and dyeing wastewater by biomass-derived carbon

印染废水污染已成为较严峻的环境污染问题之一,给生态环境和人类健康造成了极大的威胁。生物质炭材料具有成本低、原料来源广泛、比表面积大、孔隙结构发达和表面可引入功能性官能团等优点,对印染废水的吸附表现出独特的优势。综述了近年来有关生物质炭材料吸附印染废水的研究,系统介绍了生物质炭及其制备方法,生物质炭吸附印染废水的影响因素,吸附热力学参数、等温线和动力学模型,以及相关的吸附机制,并对生物质炭吸附印染废水未来的发展方向进行了展望,以期为印染废水处理提供一定的经验借鉴和理论依据。

Printing and dyeing wastewater pollution has become one of the more serious environmental pollution problems,which pose a great threat to the ecological environment and human health.Due to its virtues of low cost,wide source of raw materials,large specific surface area,well-developed pore structure,and the readily introduction of functional groups on the surface,biomass-derived carbon materials have unique advantages in the adsorption of printing and dyeing wastewater.This paper reviewed the recent research progress on the adsorption of printing and dyeing wastewater by biomass-derived carbon materials,systematically introduced the definition of biomass-derived carbon and its preparation methods,the influencing factors of the adsorption of printing and dyeing wastewater by biomass-derived carbon,the adsorption thermodynamic parameters,the isotherm and kinetic models,and the relevant adsorption mechanism.The future development direction of the printing and dyeing wastewater adsorption by biomass-derived carbon was also prospected,which could provide certain experience reference and theoretical basis for future researchers in the field of printing and dyeing wastewater treatment.
