Abstract
It is shown that at impact on a barley husk surface by plasma stream in waterproof mode a change of modified material surface occurs in comparison with initial material at the expense of protrusive fragments smoothing from 700–800 to 350–500 nanometers. The highest ratio of cleaning water from oil and the smallest water absorption is observed when using the sample № 22b processed in a propane-butane mix. Optimum parameters are found: working chamber pressure P = 26,6 Pas, current on anode Ia = 0,6 A, voltage on anode Ua = 2,5 kV, plasma-supporting gas consumption Q = 0,06 g/s, time t = 600 s. It is established that oil removal ratio when using the processed samples made not less than 99,8 %.
