Chalcogenide glasses are being studied as possible materials for photodegradation caused by visible radiation, chemical as well as thermal stability, biocompatibility, and non-toxicity. By recognizing the pivotal role of chalcogenide glasses in photodegradation, the present research deals with removing Crystal Violet Dye (CVD) from raw water using Er doped GeSbSe chalcogenide alloy system. This study's goal is to investigate the potential for using GeSbSeEr chalcogenide as a hazardous CVD remover and to optimize the conditions for the experiment. Kinetic equations as well as adsorption parameters have been analyzed and addressed. The effects of various factors, including temperature, contact time, adsorbent size, and pH on dye concentration as well as dye exclusion, have been studied in detail. Further, kinetic models and pseudo-first order have been studied in detail. The results show that the obtained data best matches with Langmuir and the process follows pseudo-second-order kinetics. The synthesized Er doped chalcogenide system has 80% compatibility with tap water, suggesting that GeSbSeEr is a beneficial adsorbent for removing CVD from water. This article reports on the removal of CVD using Er doped GeSbSe chalcogenide, which has not been done so far.

摘要

Chalcogenide glasses are being studied as possible materials for photodegradation caused by visible radiation, chemical as well as thermal stability, biocompatibility, and non-toxicity. By recognizing the pivotal role of chalcogenide glasses in photodegradation, the present research deals with removing Crystal Violet Dye (CVD) from raw water using Er doped GeSbSe chalcogenide alloy system. This study's goal is to investigate the potential for using GeSbSeEr chalcogenide as a hazardous CVD remover and to optimize the conditions for the experiment. Kinetic equations as well as adsorption parameters have been analyzed and addressed. The effects of various factors, including temperature, contact time, adsorbent size, and pH on dye concentration as well as dye exclusion, have been studied in detail. Further, kinetic models and pseudo-first order have been studied in detail. The results show that the obtained data best matches with Langmuir and the process follows pseudo-second-order kinetics. The synthesized Er doped chalcogenide system has 80% compatibility with tap water, suggesting that GeSbSeEr is a beneficial adsorbent for removing CVD from water. This article reports on the removal of CVD using Er doped GeSbSe chalcogenide, which has not been done so far.
