Abstract

The invention relates to a loofah complex oil absorb material. The preparation process is free from harmful and toxic pollutant and has the advantages of simple operation and high efficiency. Loofah is combined with grapheme, so as to obtain the complex oil absorb material with large pore structure and good air permeability, and can be reused for many times. The loofah complex oil absorb materialprepared by the invention has high oil absorbing property and reuse effect, and can be applied to marine oil pollution treatment and oil fume exhaust gas purification.

Description

technical field [0001] The invention relates to a loofah composite oil-absorbing material, which belongs to the technical field of preparation and application of environmental purification materials. Background technique [0002] The oil extraction and transportation process and the discharge of oily sewage from factories and cities are likely to cause oil pollution in water bodies and endanger the health of organisms, which has become a major environmental issue of concern to the world. [0003] In addition, cooking oil will be emitted into the air in the form of oil mist to form oil fume during cooking, and its harm should not be underestimated. Various toxic components in oil fume not only directly threaten human health, but also increase the content of urban fine particles and cause air pollution. Exacerbate the occurrence of smog weather. [0004] Therefore, a practical and efficient porous oil-absorbing material has been developed. In addition to its high oil-absorbin...
