| 1. | The research discovered that the nitric acid oxidation may remarkably increase , the activated charcoal surface acidic groups and bases the content , enhances the activated charcoal the superficial water affinity , falls to the phpzc value , and creates the activated charcoal structure to cave in the reduction which accumulates with the relative surface . thus in the activated charcoal adsorption drinking water has the slight pollutant performance to have the serious influence
研究发现:硝酸氧化可显著增加活性炭表面酸性基团的含量,提高活性炭的表面亲水性,降低phpzc (水溶液中固体表面净电荷为零时的ph值)值,并造成活性炭结构塌陷和比表面积的减少。使活性炭吸附饮用水中有机物的能力大大降低。 |
