| 摘 要： | 讨论了膨胀石墨吸附材料对各种油类及各种水面漂浮油的吸附实验结果，同时讨论了对乳化状低含量含油废水的吸附处理结果和对设备清洗废水的过滤处理结果，并将部分结果与棉花和活性炭对油性物质吸附的数据进行了比较。结果显示，膨胀石墨无论对各种单纯油类、水面浮油以及乳化状液中的油和低含油废水中的油都有极好的吸附脱除能力。

| Abstract: | The results about adsorption of several pure oil materials and their floating form on water with an new adsorbent of expanded graphite were discussed.Meanwhile,the results of expanded graphite in adosorption treatment of waste water containing low concentration of emulsified oil and in filter treatment of waste water from machine washing were also investigated.Some of these results were taken to be compare with those of cotton and granular activated carbon.All the results show that expanded graphite has a strong ability of adsorption,not only for the pure oil and their floating form on water,but also for the oil in oil water emulsion and the oil with very low concentration in waste water. |
