Annotatsiya

Ishda Angren ko'mirini (2BPK) metilamin va dimetilamin bilan modifikatsiyalab olingan FKMA va FKDMA adsorbentlarining Cu²⁺ va Pb²⁺ ionlariga nisbatan sorbsion xossalari o'rganilgan. Adsorbsiyaga eritma pH qiymati va kontakt vaqtining ta'siri aniqlangan hamda modifikatsiyalangan namunalar sanoat ko'miri AГ-3 bilan taqqoslangan.

В работе изучены сорбционные свойства адсорбентов FKMA и FKDMA, полученных модифицированием ангренского угля (марки 2БПК) метиламином и диметиламином, по отношению к ионам Cu²⁺ и Pb²⁺. Установлено влияние pH раствора и продолжительности контакта на процесс адсорбции, а также проведено сравнение модифицированных образцов с промышленным углём марки АГ-3.

English

The sorption properties of FKMA and FKDMA adsorbents, obtained by modifying Angren coal (grade 2BPK) with methylamine and dimethylamine, towards Cu²⁺ and Pb²⁺ ions were studied. The effects of solution pH and contact time on adsorption were determined, and the modified samples were compared with the commercial activated carbon AG-3.
