Предложено использование нативной и модифицированной подсолнечной лузги для очистки сточных вод от нефти. Установлено, что кислотная и щелочная модификации при разных температурах увеличивают сорбционные свойства подсолнечной лузги, а повышение температуры и концентрации вещества в процессе модификации подсолнечной лузги способствуют снижению остаточной концентрации нефти в модельных растворах сточных вод, очищаемых модифицированной подсолнечной лузгой. Определено, что наибольшее удаление нефти из модельных растворов сточных вод происходит при использовании для их очистки подсолнечной лузги, модифицированной 10 %-ной серной кислотой при температуре 121 °С и давлении 1 атм. Сделан вывод о том, что подсолнечная лузга, модифицированная кислотами и щелочью, позволяет повысить степень очистки сточных вод, загрязненных нефтью.

The proposal concerns the use of native and modified sunflower husks for wastewater treatment from oil. It was found that acid and alkali modified at different temperatures increase the sorption properties of sunflower husk, and an increase in temperature and concentration of the substance during modification of the husk contributes to a decrease in the concentration of residual oil in model wastewater solutions treated with modified sunflower husk. It was found that the greatest removal of oil from model solutions of wastewater occurs when sunflower husk modified with 10 % sulfuric acid are used for treatment at 121 °C and and 1 atm. pressure. It was concluded that sunflower husk modified with acids and alkalis increases the degree of purification of oil-contaminated wastewater.
