Изучены сорбционные и комплексообразующие свойства импрегнированных сорбентов на основе PAD600 по от-ношению к иону Pt(II). Определены параметры сорбционного извлечения ионов платины. Установлено, что лучшими сорбционными свойствами по отношению к катионам платины обладают импрегнированные сорбенты. На основании обработки интегральных кинетических кривых сорбции установлено, что процесс сорбции идет в соответствии с моде-лями второго порядка. Применение моделей химической кинетики показало, что вклад в общую скорость процесса также вносит стадия химического взаимодействия ионов платины (II) с функциональными группами сорбента.

PAD600 ga asoslangan impregnirlangan sorbentlarning Pt(II) ioniga nisbatan sorbsiyalanish va kompleks hosil qilish xususiyatlari o'rganildi. Platina ionlarning sorbsion ajratish parametrlari aniqlanadi. Impregnirlangan sorbentlarn-ing platina kationlariga nisbatan eng yaxshi sorbsion xususiyati borligi aniqlandi. Integral kinetik egri chizig'ini qayta ish-lashga asoslangan holda sorbsiya jarayoni ikkinchi darajali modellarga mos kelishi aniqlangan. Kimyoviy kinetika model-larining ishlatilishi platina (II) ionlarining sorbentning funktsional guruhlari bilan kimyoviy ta'sirlanish bosqichi ham umumiy sorbsiya jarayoni tezligiga yordam berishini ko'rsatdi.

The sorption and complex-forming properties of PAD600-based impregnated sorbents with respect to the Pt (II) ion were studied. The parameters of sorption extraction of platinum ions are determined. It was found that impregnated sorbents have the best sorption properties with respect to platinum cations. Based on the processing of the integral kinetic sorption curves, it has been established that the sorption process proceeds according to second-order models. The use of chemical kinetics models has shown that the stage of chemical interaction of platinum (II) ions with functional groups of the sorbent also contributes to the overall process rate.
