| Abstract: | The bacterial cellulose sodium sulfate was prepared from bacterial cellulose and used for the removal of copper ions in water. The structure of the sample was analyzed by IR. The parameters affecting the exchange capacity, such as contact time, temperature, and sulfuric acid concentration have been investigated, which exchange capacity was 2.87mmol·g^-1 under the optimum condition, and its adsorption properties for copper ions were investigated. The results showed that the bacterial cellulose sodium sulfate has stronger adsorption ability to copper ions and its regeneration was easy. |
