Ushbu maqolada ekologiyaga, asosan ichimlik suvini zararli metall ionlari va konserogan moddalar bilan ifloslanish yo‘llari hamda ularni tozalashda foydalaniladigan kimyoviy, fizikaviy, texnologik usullarni afzallik va kamchiliklari haqida ma’lumot berilgan. Bu usullardan sorbsiya jarayoning boshqa usullardan afzalliklari keltirilgan. Shuningdek, mualliflar tamonidan o‘rganilgan suvni zararli moddalardan tozalashda ishlatiladigan biosorbentlar olish sharoitlari va ularning sorbsion xossalari keltirilgan. Biosorbent olishda tabiiy polimer chiqindilari, manbalari va ularni qayta ishlash sharoitlari yoritib berilgan. Sholi qobig‘ini aktiflash, mehnik ishlov berish va uni mochavina bilan modifikatsiyalash mahsulotini boshqa biosorbentlarga nisbatan sorbsion xossalari solishtirilgan. Bundan tashqari, tabiiy polimerlarni manbalariga ko‘ra turlari va ularning sun’iy metall tuzlari eritmalaridan 1 g sorbent uchun sorbsiya miqdorlari keltirilgan. Biomateriallarning sorbsion xossalarini Fredlix va Lingmur izoterma modeli metodlaridan foydalanilgan. Yutilgan metall ioni miqdorini aniqlashda SHIMADZU (UV-1900) spektrofotometrdan foydalanildi.

В данной статье приведены сведения об окружающей среде, в основном о путях загрязнения питьевой воды вредными ионами металлов и канцерогенами, а также о преимуществах и недостатках химических, физических, технологических методов, применяемых при их очистке. Из этих методов вытекают преимущества сорбционного процесса перед другими методами. Авторами также изучены условия получения биосорбентов, используемых при очистке воды от вредных веществ, и их сорбционные свойства. Описаны природные полимерные отходы, источники и условия их переработки при производстве биосорбентов. Проведено сравнение сорбционных свойств продуктов активации, механической обработки и модификации мочевины рисовой шелухи по сравнению с другими биосорбентами. Кроме того, приведены виды природных полимеров по их источникам и количествам их сорбции на 1 г сорбента из растворов искусственных солей металлов. Сорбционные свойства биоматериалов использовали изотермическими модельными методами Фредликса и Лингмура. Для определения количества абсорбированного иона металла использовали спектрофотометр SHIMADZU (UV-1900).

The article provides information on the environment, ways of contaminating the water of fixed assets with harmful metal ions and carcinogenic poisoning, as well as the advantages and material disadvantages of purified, physical, technological methods of their treatment. Removal of the sorption process from these methods by other methods. The author studied the conditions for obtaining biosorbents in the treatment of water and the site sorption. Natural polymers, sources and conditions of their processing are described in the production of biosorbents. The sorption properties of rice activation, mechanical harvesting and urea modification products were compared with other biosorbents. In addition, 1 g sorption capacity is extracted from sources of natural polymers by type and source of artificial metal salts. The sorption properties of biomaterials were used by the Fredlix and Lingmur isothermal model methods. A SHIMADZU (UV-190) spectrophotometer was used to estimate the amount of metal ion absorbed.
