摘要
【目的】亚甲基蓝应用广泛,但具有较大的毒性,且难以降解,因此寻求一种高效且低成本的方法处理染料废水显得尤为重要。【方法】笔者从几种常见的农业生物质着手,对硅藻土、花生壳、柚子皮和橘子皮改性前后对亚甲基蓝吸附的研究进展进行了综述总结。【结果】即使是同一种类的生物质以不同方法进行改性,改性后的生物质吸附剂对亚甲基蓝的去除效果在一定程度上也会有所提高。【结论】生物质吸附剂不仅来源丰富,而且对亚甲基蓝的吸附效果良好,具有广阔的应用前景。
[Purposes] Methylene blue is widely used,but it is highly toxic and difficult to degrade,so it is important to find an efficient and low-cost method to treat dye wastewater.[Methods] Starting from several common agricultural biomasses,the author reviewed and summarized the research progress on the adsorption of methylene blue by diatomaceous clay,peanut shell,grapefruit peel and orange peel before and after modification.[Findings] The results showed that even when the same type of biomass was modified by different methods,the removal of methylene blue by the modified biomass adsorbent was improved to some extent in all cases.[Conclusions] This indicates that the biomass adsorbent is not only abundant in source,but also has good adsorption effect on methylene blue and has a broad application prospect.
