This study investigates the utilization of nano-composite hydrogels for the removal of methyl violet from aqueous solutions, leveraging a Fenton-like reaction mechanism. The nano-composite hydrogel demonstrated exceptional efficiency in dye removal, attributed to the synergistic effects of the hydrogel matrix and the catalytic activity of embedded nano-particles. This process generates hydroxyl radicals under mild conditions, leading to the effective breakdown of various industrial dyes. The kinetics of dye removal, the reusability of the nano-composite, and the influence of operational parameters such as different amounts of nano-composite, pH, , temperature, and dye concentration were systematically explored. The findings underscore the potential of nano-composite hydrogel as a promising, environmentally friendly solution for wastewater treatment and dye removal.

Атрофдаги оламни билиш - унинг моделларини яратишдан иборат. Улар ушбу олам объектлари билан бизнинг ўзаро таъсиримиз оқибатларини кўриш имконини беради. Моделларни яратиш инсон тафаккурининг ташкилий тузилишини такомиллаштириш жараёни ҳисобланади. Мазкур психологик ташкилий тузилиш мақсадга йўналган ҳаракатлар кўринишида моддийликка айланади, уларни инсон ўзида мавжуд моделлар асосида амалга оширади. Ушбу мақолада математик моделлаштиришнинг асосий масалалари ҳақида фикрлар ёритилган.

Empathy is not only a vital emotion in interpersonal relationships, but also a core component of social consciousness, culture, and interpersonal intelligence. The student age is a particularly active period for the development of this ability. A pressing issue today is the low level of empathy among students and the need to develop effective psychological approaches to enhance it.
