At the National Research University "Moscow Power Engineering Institute" in collaboration with the Joint Institute for High Temperatures of the Russian Academy of Sciences, a new effective peat absorbent has been developed for removing oil products from the surface of soil and water. This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
Specialists treated the peat with low-temperature plasma (ionized gas consisting of electrons, ions, and neutral particles).
Plasma conditions were created at atmospheric pressure by a high-frequency induction plasmotron using argon as the plasma-forming gas. The operating frequency of the plasmotron is 27.12 plus or minus 0.27.
Sorbents based on peat have already proven themselves as effective oil absorbers. One gram of peat is capable of absorbing up to two or more grams of oil.
We can already say that the oil capacity of peat tablets treated in a high-frequency plasmotron is doubled due to changes in the structure of the peat fibers. Thanks to this method, a partial change from hydrophilicity to hydrophobicity occurs, which increases the absorption capacity of peat tablets and allows them to retain oil.
Earlier, www1.ru reported that scientists from KubSTU developed an innovative method for cleaning sand from oil products.
