摘要
未活化、热活化和酸活化的海泡石在前４ｈ内对有毒化学气体的吸附速率比其本身以后的吸附速率大几到十几倍；酸活化比未活化和热活化的样品吸附作用时间增长１倍以上，吸附饱和度增大４倍左右；气源液体沸点较低而蒸气压较大者比沸点较高而蒸气压较小者，其气体被吸附量前者比后者大３倍左右；同类型的化学物质分子体积较小和形状较规则者易被吸附．
During 4 hr of early stage the absorpt rate of unactivated and teat-acid activatedsepiolite to poisonous chemical gases is more than ten times greater than their absorpt ratelater on.The absorption time and the absorpt saturability of acid-activated sepiolite is over1 times longer and about 4 times greater than unactivated and heat-activated separately.The absorbent amount of the gas produced by the liquid characterizing by lower boilingpoint and greater vapour pressure is about 3 times greater than the gas produced by the liquid characterizing by higher boiling point and less vapour pressure. For the chemical substance of same type, one characterizing by smaller molecule volume and more regular shapeis absorbed easily.
