            <abstract>
                <p>Various methods are used to combat oil spills in water bodies: mechanical collection (to eliminate the bulk of the spill) and application of carbon sorbents derived from plant materials to the water surface (to remove residual contaminants). The proposed solution is the use of biochar obtained by pyrolysis of almond husks with uniform heating to 650°C for 100 minutes and isothermal holding for 40 minutes. The adsorption properties of the biochar were studied under laboratory conditions. Tests to remove oil from fresh and salt water were conducted in a Petri dish by applying an oil film to the water surface followed by distributing sorbent materials, including biochar from almond husks. The applicability of the adsorbent was assessed taking into account environmental factors such as salinity and water temperature in Arctic (polar) regions. The study revealed that almond husk biochar has high porosity and removes oil film within one hour, while the recommended absorbent dose is 4 g/L (30 g/m2). It was noted that under Arctic (polar) conditions, the use of the sorbent at the selected dose ensures visible removal of the oil film. The oil-saturated sorbent remains buoyant for three days and is easily collected from the surface mechanically.</p>

                <p>Для борьбы с нефтяными загрязнениями в водных объектах используются различные методы: механический сбор (для ликвидации основной массы разлива) и нанесение на поверхность воды углеродных сорбентов, полученных из растительных материалов (для удаления остаточного загрязнения). Предлагаемым в работе решением является применение биоугля, полученного пиролизом из шелухи миндального ореха при равномерном нагревании до 650 °С за 100 мин и изотермической выдержке в течение 40 мин. Адсорбционные свойства биоугля исследованы в лабораторных условиях. Испытания по очистке пресной и соленой воды от нефти проведены в чашке Петри нанесением пленки нефти на поверхность воды и последующим распределением сорбирующих материалов, включая биоуголь из шелухи миндального ореха. Применимость адсорбента оценена с учетом факторов среды – солености и температуры воды в арктических (полярных) областях. В результате исследования выявлено, что биоуголь из шелухи миндального ореха обладает высокой пористостью, ликвидирует пленку нефти в течение одного часа, а рекомендуемая доза поглотителя составляет 4 г/л (30 г/м2). Отмечено, что в арктических (полярных) условиях применение сорбента в выбранной дозе обеспечивает видимую ликвидацию пленки нефти. Насыщенный нефтью сорбент сохраняет плавучесть в течение трех суток и легко собирается с поверхности механическим способом.</p>
