活性炭吸附化学战剂--沙林染毒水的试验研究

研究了 5种国产活性炭吸附水中沙林的性能及影响因素。果壳质活性炭的吸附性能优于煤质活性炭。果壳活性炭WP 2 0 2的吸附等温线方程为 qe=11 45C0 39e ,其粉状炭在 10min时能达到吸附容量的 98%。活性炭颗粒小则吸附速度快 ,温度升高不利于吸附。活性炭与水中的氯反应后 ,吸附性能下降 3 0 % ,在含盐量 2 0 0 0mg/L的苦咸水中吸附量降低 5 %。处理化学战剂 -沙林染毒水宜多种水处理技术相结合 ,并采用活性炭吸附作为最后一级处理单元

Treatment of chemical warfare reagent--sarin contained water by adsorption of activated carbon

The capacity and influencing factors of the adsorption chemical warfare reagent - sarin contained water by 5 kinds of activated carbon are discussed. The activated carbon made of shell has better capacity than that of coal. For activated carbon WP-202 ,the adsorption isotherm equation is q e=11.45 C 0.39 e, and it's powdered form reach 98% of the adsorption capacity within 10 min. The adsorption speed has an anti-correlation with the diameter of activated carbon. The increase in temperature has disadvantage to the adsorption. The adsorption capacity of activated carbon decreased by 30% to 5% respectively when reacted with chlorine and in saline water which contain 2000 mg/L of NaCl. For the treatment of chemical warfare reagent - sarin contained water,it's the best way by the integrated use of different water treatment units ,and use the activated carbon adsorption as the last unit.
