The contamination of water bodies by synthetic dyes, namely methylene blue (MB), is a significant environmental concern due to their contrary effects on aquatic ecosystems. This study proposes novel approach integrating magnetic properties into activated carbon improve the removal efficiency and simplifies separation process. synthesis involved impregnation (Rice husk as precursor) with iron oxide nanoparticles ((Fe3O4-RAC), which imparted matrix. characterization studies were performed perceive morphology adsorbent. adsorption tests examined under various factors such contact time, initial MB concentration, adsorbent dosage pH. data revealed that equilibrium onto Fe3O4-RAC was achieved within 60 min, maximal strength 32.25 mg g−1. Langmuir model (R2 = 0.997) demonstrated best fit, suggesting monolayer behaviour. Furthermore, kinetics tailed pseudo-second-order 0.995), indicating chemisorption rate-determining step. results indicated positive correlation between temperature adsorption, signifying endothermic nature. facilitated from treated solution using an external field, eliminating need for additional filtration or centrifugation steps. regeneration also investigated, it found composite could be efficiently regenerated ethanol desorption agent, allowing repeated use. In conclusion, promising potential efficient reusable wastewater.

The development of efficient photocatalysts is crucial in addressing water pollution concerns, specifically the removal organic dyes from wastewater. In this context, use silver nanoparticles (Ag NPs) might represent a method to achieve high dye degradation efficiencies. On other hand, classical Ag NP production process involves several reactants and operating conditions, which make it poorly sustainable. present work, NPs were synthesized according new sustainable involving natural extracts Spirulina platensis milder conditions. material was also calcined determine influence content on properties NPs. X-ray diffraction (XRD) analysis displayed AgCl phases with crystalline size 11.79 nm before calcination. After calcination, only phase an increased 24.60 nm. Fourier Transform Infrared Spectroscopy (FTIR) confirmed capping role metabolites extract.
