In this work, silver nanoparticles (AgNPs) were elaborated using a simple, low-cost, and reproducible method by thermal treatment at 90°C of chitooligosaccharides (COSs), produced chitosan depolymerization the digestives chitosanases from Portunus segnis viscera, in presence AgNO 3 . The characterization obtained AgNPs, UV–visible spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), Fourier-transform infrared (FTIR) spectroscopy analyses, showed that they are crystalline, spherical stable for month 4°C. Moreover, biological properties synthesized AgNPs evaluated, proving exhibited interesting antioxidant antibacterial activities. present investigation suggested COSs will be good source preparation could useful different industrial biomedical applications.

A functionalized chitosan thiourea composite (CH-TU) was successfully synthesized using formaldehyde as a crosslinking agent for enhancing silver recovery from different aqueous solutions. Comparison sorption studies with non-functionalized (CH-F) reference material were conducted. Grafting led to an improvement in the performances, i.e., 0.763 mmol Ag g−1 CH-F vs. 2.125 CH-TU. The pseudo-first-order rate equation (PFORE) fitted kinetics at saturation times of 40 and 30 min CH-TU, respectively, while isotherms Langmuir Sips equations both sorbents. Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), nitrogen sorption–desorption (BET-surface area), elemental analysis, thermogravimetric (TGA) pH zero charge (pHpzc) used characterize investigate mechanism. Sorption performed three check reproducibility, performances stable over 20 cycles, limited decrease performance (5 3% respectively). Nitric acid solution (0.3 M) efficient desorbing adsorbed metal ions. grafted sorbent is considered promising tool recovering Ag(I) acidic waste leachate derived spent films.

Environmental pollution with heavy metals is one of the most important environmental problems this century. Bioaccumulating in food chain, exhibit high toxicity toward living organisms. To prevent serious risks to human health, eliminating these air, soil, and water great importance. The chapter reviews modern data on distribution environment, organisms, their toxicity, development new effective sorbents for removal from environment A large number studies are devoted synthesis, modification, properties sorption materials metals. New information presented field application enterosorption method as promising areas removing organism, well prophylaxis treatment various diseases.
