| 摘 要： | 以天然木屑为原料,通过碱化和用阳离子表面活性剂共同改性制备低成本吸附剂,通过静态吸附实验探讨了改性木屑和3种颗粒活性炭对阿特拉津(AT)的吸附行为.结果表明,改性后的木屑对AT的吸附能力明显增强,在AT质量浓度为100μg/L的务件下,改性木屑对AT的去除率可达90%.通过采用FTIR、SEM等分析手段对材料改性前后进...

| Abstract: | A low-cost adsorbent was prepared by the modification of alkalization and cationic surfactant using sawdust as raw material.The adsorption process of the modified sawdust and three kinds of granular activated carbon on atrazine(AT) was discussed though static adsorption experiment.Result indicated that the adsorption capacity of sawdust was obviously enhanced after modification,and the removal rate of the modified sawdust could reach about 90% with AT at 100 ug/L.Meanwhile,the structure of sawdust after mod... |
