摘要

用一种商用去角质石墨对废水中发动机油和染料的吸附能力进行了测试。剥落石墨在400℃空气中轻微氧化可有效提高对染料、亚甲基蓝和甲基橙的吸附能力。然而,在HNO3中处理后,其对机油和染料的所有性能都降低了。揭示了同时去除废水中分散的油脂和染料的可能性。

Exfoliated Graphite as a New Sorbent for Removal of Engine Oils from Wastewater

A commercial exfoliated graphite was used for checking its sorption capabilities for removing engine oil and dyes from wastewater. Slight oxidation of exfoliated graphite in the air at 400 °C was found to be effective to improve adsorption capacity for dyes, methylene blue and methyl orange. However, its treatment in HNO3 reduced all capacities for engine oil and dyes. A possibility for simultaneous removal of oil and dyes dispersed in wasted water was revealed.
