Abstract[English]
This research indicates a new kind of bio-self-assembled nanocomposite hydrogel based on natural xanthan polymer and sodium montmorillonite nanoparticle in the field of polymers, which is modified by Triaminopropyl triethoxysilane. This process does not contain any chemical cross-linking agent and it also has been synthesized; this bio-self-assembled nanocomposite hydrogel aims to function as a removal of heavy metals from drinking water and wastewater because it has the property to absorb ions. The self-assembling hybrid nanocomposite hydrogel is composed of xanthan gum which is a natural polymer and sodium montmorillonite which is an unmodified clay nanoparticle with precursor triaminopropylene triethoxysilane and hydrolysis of the precursor to stabilize nanoparticles to increase the surface area absorbent matrix, abundant binding and absorption sites, improvement of swelling behavior; the increase of the absorption capacity of heavy metals in the absence of any crosslinking agent was designed and synthesized.[French]
Cette recherche indique un nouveau type d'hydrogel nanocomposite bio-auto-assemblé à base de polymère de xanthane naturel et de nanoparticule de montmorillonite sodique dans le domaine des polymères, qui est modifié par triaminopropyle triéthoxysilane. Ce processus ne contient pas d'agent de réticulation chimique et il a également été synthétisé ; cet hydrogel nanocomposite bio-auto-assemblé vise à fonctionner pour éliminer des métaux lourds de l'eau potable et des eaux usées, car il a la propriété d'absorber des ions. L'hydrogel nanocomposite hybride à autoassemblage est composé de gomme xanthane qui est un polymère naturel et de montmorillonite sodique qui est une nanoparticule d'argile non modifiée avec un précurseur triaminopropylène triéthoxysilane et hydrolyse du précurseur pour stabiliser des nanoparticules pour augmenter la matrice absorbante de surface superficielle, des sites de liaison et d'absorption abondants, une amélioration du comportement de gonflement ; l'augmentation de la capacité d'absorption de métaux lourds en l'absence de tout agent de réticulation a été conçue et synthétisée.
