Abstract In this work, hydroxypropyl starch sulfate (HPSS) and Aspergillus oryzae ( Asp. ) were successfully synthesized investigated for aqueous methylene blue (MB) adsorption. The as-prepared adsorbents also characterized extensively using FTIR, XRD, SEM, EDX, BET surface area analyses to elucidate their functional, textural, morphological properties. Also, the effects of initial dye concentration, contact time, pH on adsorption performance both systematically investigated. Due significant differences, HPSS recorded a higher maximum capacity q max 52.41 mg/g at 20 mg/L 60 min, 8.0, while 37.26 9.0. Specifically, –SO 3 groups shared some electrostatic affinity with MB cationic center (N + backbone), hydrogen bond is formed between hydroxyl N backbone dye. nitrogen- oxygen-containing provided active sites binding species. XRD spectra loaded showed decrease in sharp crystalline peaks, no structural changes observed case . Therefore, effectiveness adsorbing was established study.

Abstract Introduction . Polyvinylidene fluoride (PVDF) is widely used in various industries, particularly water treatment, owing to its effectiveness as an ultrafiltration membrane. Fouling can occur on PVDF membranes during the treatment of aqueous solutions containing natural organic matter treatment. Nanofillers be added improve their durability for more applications Objectives This study aimed enhance mechanical and anti-biofouling properties while maintaining flux rejection rates. Methods A green method was synthesize Ag-Nanoclay nanocomposite integration into a polymer P. argentea extract employed reducing stabilizing agent synthesis nanocomposites. The synthesized characterized using X-Ray Diffration (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM). phase inversion prepare 1 wt% 3 membranes. structures, morphologies, performances antibacterial proeprties prepared were characterized. Results consisted Ag Nanoparticles linked nanoclay platelets with flavonoids from plant extracts. Incorporating membrane resulted minor increases pore size, roughness, hydrophobicity However, these effects did not significantly affect rates, which showed little improvement. loading improved tensile strength by 67%, whereas it decreased 50% at loading. Both levels demonstrated excellent activity against Escherichia coli ( E. ) Staphylococcus aureus S. ), sterilization rates exceeding 99%. Conclusions Addition promising strategy developing advanced characteristics.
