摘要:

染料工业的发展使得染料废液处理成为环境保护的一大挑战,生物炭由于高比表面积和丰富的表面官能团,在吸附废液染料物质方面表现出色,成为一种高效、经济且环境友好的吸附材料。本文综述了生物炭染料吸附过程中的吸附机理与影响因素,归纳总结出:生物炭对染料废液的吸附机理,包括氢键作用、π-π相互作用、静电相互作用、配位作用和离子交换作用,这些作用共同决定生物炭与染料分子之间的相互作用和吸附效率;影响生物炭吸附能力的因素,包括制备生物炭的原料、改性方式和制备工艺等;废液性质如溶液pH和离子浓度等因素对生物炭吸附染料能力也有影响。提出当前生物炭吸附研究中存在的问题,如研究对象单一、工艺与成本和对环境的影响等。本文旨在为后续研究提供参考,以推动生物炭在染料废液治理中的实际应用。

Abstract:

The development of dye industry makes the treatment of dye waste liquid a challenge for environmental protection. Due to the high specific surface area and rich surface functional groups, biochar has excellent performance in adsorption of waste liquid dye substances, which makes it an efficient, economical and environmentally friendly adsorption material. This paper reviewed the adsorption mechanism and influencing factors of biochar in the dye adsorption process. It was pointed out that: (1) the adsorption mechanism of biochar on dye waste liquid including hydrogen bonding, π-π interaction, electrostatic interaction, coordination and ion exchange, jointly determined the interaction and adsorption efficiency of biochar and dye molecules. (2)The factors affecting the adsorption capacity of biochar included the raw materials, modification methods and preparation processes of biochar. (3)The properties of waste liquid, such as solution pH and ion concentration, also affected the adsorption capacity of biochar for dyes. Finally, the problems in the current biochar adsorption research, such as the single research object, the process and cost, and the impact on environment, had yet to be solved. This paper provides a reference for subsequent research to promote the practical application of biochar in the treatment of dye waste liquid.
