摘要
在吸收管中加正己烷和脱脂棉可以很好的吸附气体中的油分，其吸附率达９０％以上。用紫外分光光度计在２６０ｎｍ处可测出溶解在正己烷中的油分。
N hexane and degreased cotton placed in the absorbing tube can satisfactorily adsorb the oil in gases,the adsorption rate is over 90%.The oil disolved in the n hexane can be measured with a UV spectrophotometer at 260nm wave length.
