Analysis of sorbing method of water treatment from oil

Abstract

The efficiency of simple and accessible methods of cleaning of oil-contaminated water is investigated. The maximum absorption capacity of cotton as a natural material is identified, that quickly absorbs oil components and does not require the use of additional resources to combat water contamination. It is found that natural charcoal absorbent is inefficient in comparison with other methods of water purification from oil and requires a long time and additional pollution catchers, which is economically unprofitable. Synthetic polymer foam and white coal absorb oil in a short time, but in the latter case, nevertheless, small spots remain on the surface of the water. According to the efficiency of oil absorption by natural and synthetic materials, we can distinguish the following series of investigated materials: black coal → foam → white coal → cotton.
