Tadqiqot maqsadi polivinilxlorid asosida olingan yangi sorbentning fizik-kimyoviy xossalarini o‘rganishdan iborat. Tatdqiqotlar termogravimetrik analiz, differentsial termik analiz, kompleksonometriya kabi zamonaviy usullar yordamida eksperimental natijalar olinganligi bilan asoslangan. Sorbent va sorbat o‘rtasidagi ion muvozanati Lengmyur va Freundlix izoterma modellari, sorbsiya termodinamikasi haqidagi zamonaviy nazariyalarda ishlatiladigan tenglamalarni qo‘llash orqali xulosalar chiqarilgan. PVX asosida olingan ionitning fizik kimyoviy xossasi o‘rganish natijasida yuqori termik barqarorlikka egaligi va metall ionlarining yutilishi yuqori darajada ekanligi aniqlangan.

Целью исследования явилось изучение физико-химических свойств нового сорбента на основе поливинилхлорида. Исследование основано на том, что экспериментальные результаты были получены с использованием современных методов, таких как термогравиметрический анализ, дифференциальный термический анализ, комплексонометрия. Ионное равновесие между сорбентом и сорбатом выводится из моделей изотерм Ленгмюра и Фрейндлиха с использованием уравнений, используемых в современных теориях термодинамики сорбции. Изучение физико-химических свойств ионообменников на основе ПВХ показало, что они обладают высокой термической стабильностью и высоким поглощением ионов металлов.

The purpose of the study Is to study the physicochemical properties of a new polyvinyl chloride-based sorbent. The research is based on the fact that experimental results were obtained using modern methods such as thermogravimetric analysis, differential thermal analysis, complexonometry. The ionic equilibrium between the sorbent and the sorbate is deduced from the Langmuir and Freundlich isotherm models, using the equations used in modern theories of sorption thermodynamics. The study of the physicochemical properties of PVC-based ion exchangers revealed that they have high thermal stability and high absorption of metal ions.
