摘要
Abstract
The technical conditions of preparation of activated carbon from waste cotton were studied.The results show that adsorption capacity of activated carbon increases first and then decreases with phosphoric acid concentration,impregnation time,activation temperature and time increasing.Optimum conditions are as follows: phosphoric acid concentration of 40%,impregnation time of 24 h,activation temperature of 500℃ and activation time of 30 min.Under the best conditions,the prepared activated carbon is better than commercial activated carbon.Through thermo gravimetric analysis,the phosphoric acid activation mechanism of waste cotton was discussed.The preparation process of waste cloth activated carbon can be divided into five stages: evaporation,carbonization,transition,activation and calcination.关键词
