选用两种有机酸对活性炭进行了改性处理,以改性后的活性炭为载体,添加活性组分后制备成浸渍炭,考察了有机酸的浓度、处理温度和时间对浸渍炭防护氯化氰的影响。研究发现有机酸B改性可明显提高浸渍炭对氯化氰的防护性能,且对不同类型活性炭的防护性能均有不同程度提高,经试验确定最佳改性工艺为:浓度0.2mol/L的有机酸B于50℃下改性处理2h。
Two kinds of organic acids were used to modify the activated carbon. The modified activated carbon was used as the carrier, and the active component was added to prepare the impregnated carbon. The effects of concentration of organic acid, treatment temperature and time on the adsorption of cyanogen chloride Impact. It was found that the modification of organic acid B can significantly improve the protective performance of impregnated carbon on cyanogen chloride, and the protective properties of different types of activated carbon have increased in varying degrees. The best modification process determined by the experiment is: 0.2mol / L Organic acid B was modified at 50 ℃ for 2h.
