Abstract
La présente invention décrit une méthode de préparation du charbon actif à partir des coquilles de noix d'Argan préparé par activation chimique à l'aide de l'acide borique H3BO3 et de l'acide phosphorique H3PO4 pour l'élimination du Diclofénac, ce matériau a été caractérisé par microscope électronique à balayage, spectrométrie infrarouge à transformée de Fourier, diffraction des rayons X sur poudre, Brunauer– Potentiel Emmet-Teller et Zeta. L'adsorption du Diclofenac, un médicament anti-inflammatoire, à partir d'eau distillée par des tests cinétiques, d'équilibre et thermodynamiques a été étudiée. Des expériences en mode discontinu ont été menées pour évaluer la capacité d'adsorption du Diclofenac à partir d'une solution aqueuse en utilisant le carbone ci-dessus. Les résultats d'adsorption ont montré que le temps d'équilibre est de 90 minutes. L'adsorption du Diclofénac sur du charbon actif produit à partir de coquilles de noix d'Argan est décrite par un modèle cinétique de pseudo-second ordre. La capacité d'adsorption la plus élevée déterminée par le modèle de Langmuir est d'environ 233 mg/g. Les paramètres thermodynamiques indiquent que le processus d'adsorption est spontané (-ΔG°) et exothermique (-ΔH°).
