吸附型固载二氧化氯吸附剂性能的研究

Investigation on the Absorbent Performance of Chlorine Dioxide by Solid Carrier

研究了4种吸附剂AC1、AC2、GZT及ATBT对二氧化氯的吸附性能,探讨了吸附剂的比表面积和孔结构对二氧化氯吸附性能的影响。重点研究了NH3.H2O改性后AC1的孔结构和表面酸碱基团变化对其吸附性能的影响。结果表明,吸附剂的微孔孔容及比表面积越大,越有利于对二氧化氯的吸附;与AC1相比,经NH3.H2O改性后的活性炭GAC1表面碱性基团含量、微孔孔容及微孔面积增加,从而提高了其对二氧化氯的吸附性能。

The absorption experiments of chlorine dioxide were carried out by four adsorbents including AC 1, AC2, GZT and ATBT. The effects of pore texture and surface properties of the absorbents on their absorption performance of chlorine dioxide were investigated. The results showed that larger micro volume and micro-pore area of the absorbents had better absorption performance of chlorine dioxide. Compared with AC1, GAC1 modified by impregnating with ammonia had better absorption performance of chlorine dioxide because the surface alkali basic groups, pore volume and micro-pore area of GAC1 increased.
