Abstract The current study reported a facile co-precipitation technique for synthesizing novel NiCo 2 S 4 /chitosan nanocomposite. photocatalytic activity of the prepared nanocomposite was evaluated using congo red (CR) dye as target pollutant. central composite design employed to examine impact different reaction conditions on CR degradation. This selected pH, photocatalyst loading, initial concentration and time parameters, while degradation efficiency (%) response. A desirability factor 1 suggested adequacy model. Maximum 93.46% 35 ppm solution observed after 60 min visible light irradiation. response surface methodology (RSM) is helpful predict optimum photodegradation dye. Moreover, /Ch displayed high recyclability reusability up four consecutive cycles. present suggests that could prove be viable treatment dye-contaminated wastewater.

Abstract Due to concerns about the accessibility of clean water and quality treated wastewater, developing a suitable solution enhance is critical. Thus, current study focused on synthesis cadmium-doped CdIn 2 S 4 incorporated in chitosan, forming Cd/CdIn @Ch quantum dots using solvothermal technique for efficient photodegradation hazardous pollutants like ofloxacin para-nitrophenol through H O -mediated AOP. were characterized by several advanced methods, including XRD, PL, UV-DRS, FTIR, SEM, HR-TEM, XPS, DSC, TGA, EDX, Elemental mapping analysis. The influence varying reaction parameters, such as effect organic compounds, inorganic ions, matrices, was also investigated. prepared composite showed outstanding efficiency 85.51 ± 1.35% 96.70 1.31%, with rate constant 0.02334 0.15134 min −1 , which 1.24 2.07 times higher than pristine para-nitrophenol, respectively. COD values reduced 80.67 1.67% 88.36 1.43% whereas TOC 73.49% 86.34%, respectively, from their initial values. improved performance ascribed encapsulation leading self-doping cadmium into photocatalyst, doping site can generate local electron accumulation point, improving charge separation efficacy surface mitigation capability chitosan nanosheets even further. scavenger experiments that hydroxyl superoxide radicals played significant part contaminants. Additionally, excellent constancy recyclable up six times, suggesting exceptional stability reusability manufactured photocatalyst. fabricated could be an photocatalyst removing wastewater near future.
