咖啡渣制备活性炭及其在环境污染治理应用进展

Preparation of Activated Carbon Made from Coffer Grounds and Its Application in the Environmental Pollution Control: A Review

从咖啡渣活性炭的制备技术及其环境污染治理应用两方面综述了国内外咖啡渣活性炭的研究进展。总结了咖啡渣活性炭的炭化、物理活化法和化学活化法的发展状况,同时综述了咖啡渣活性炭在重金属、有机物和废气吸附等方面的应用进。提出了目前咖啡渣活性炭生产应用技术存在的问题及咖啡渣活性炭未来的研究方向。

The current review provides a summary of knowledge and research developments concerning the preparation of activated carbon from coffer grounds and its application in the environmental pollution field. It also focuses on the carbonization, physical and chemical activation for the active carbon from coffer grounds. Meanwhile, the review of the coffer grounds activated carbon source was employed in environmental fields like the absorption of heavy metal, organic and waste air. Finally, many issues hindered the application of coffer ground in preparing for the activated carbon and future development direction of activated carbon with coffer grounds were discussed.
