| 摘 要： | 在测定CODCr的回流装置内，用混酸（H2SO4＋HNO3）将分析纯二硫化碳中的微量苯系物硝化，得到除去苯系物的二硫化碳，回收的混酸可以再用作硝化剂。该提纯的二硫化碳500ml成本35元，是进口或出口低苯系物二硫化碳的1／40。

| Abstract: | In the reflux apparatus for CODcr determination, the mixed acid （HzSO4 ＋ HNO3） is used to get rid of BTEX. The carbon disulfide without BTEX is obtained after the nitration. The recycled mixed acid can be reused as nitration. The cost of purified carbon disulfide is about 35RMB/500ml, about one fortieth of the imported or ex- ported carbon disulfide with low BTEX. |
