活性炭纤维及其在水处理方面的应用现状

活性炭纤维是有机纤维材料经炭化，活化制成的一种新型吸附材料，具有独特的物理．化学结构和吸附速度快、容量大、含碳量高、再生容易的特点，比传统活性炭具有更好的吸附性能，应用前景广阔，目前已用于水质净化、废水处理等方面，而且处理效果明显、应用价值高。但由于其价格较高．对大分子污染物的吸附性较差等因素，使得活性炭纤维在水处理中的广泛使用受到一定程度的限制。因此，应当对其加强开发研究，拓宽在水处理中的应用范围。

APPLICATION AND ACTUALITY OF ACTIVATED CARBON FIBER AND ITS USE IN WATER TREATMENT

The activated carbon fiber（ACF）is a new type adsorbs material,which was prepared from the organic fiber by carbonization and activation. ACF has the unique physics and chemistry structure. Its characteristics are fast absorption, large capability of absorption, high carbon content, and also it can be reproduced easily. It has better absorbability and wider applications than the traditional activated carbon. Now, it has been used in water purification, wastewater treatment, and so on, and their effect is obvious with the higher application values. But due to its higher price and the worse absorbability for the big molecule contamination, the applications of ACF in water treatment are restricted to some extent. Therefore, we would strengthen the research in ACF, and extend its ranges of application in water treatment.
