利用 ESR 法分析自由基

Analysis Radical by ESR Method

卷烟烟雾中自由基对人体健康是有害的，寻找易于加工、价格低廉、高效低毒的自由基清除剂，同时它又具有吸附卷烟中的焦油，这是十分有意义的。利用ＥＳＲ法测定了卷烟焦油中自由基的含量，同时测定了经过加工的蒙脱石制成的复合滤嘴卷烟烟雾中的自由基，经过对比，发现卷烟焦油中自由基下降（３２±３）％。

It is radical of cigarette smoke that does harm to the health.It is very important to find radical scavenger which is easy processness,low price,high effitcient,low poison,and it is useful to absorb the tar of cigarette.Using ESR method,the containing of radical of cigarette tar and radical of cigarette smoke of compound filter made by processed montmorillonite wear measured.We find that radical of cigarette tar descends(32±3)% by contrasting.
