چکیده

Abstract Ginkgo biloba (Ginkgo)/calcium silicate nanocomposite (NG-CSA) was prepared as a novel sorbent. Nanomaterial characterized using different techniques such Fourier transform infrared spectroscopy, scanning electron microscopy, transmission X-ray diffraction, differential thermal analysis and gravimetric (DTA TG). Adsorption of Sr(II) Cd(II) ions performed taking into account significant parameters initial pH the solution, shaking time concentration metal well temperature. The acquired results were disclosed that adsorption both is notably improved NG-CSA composite. monolayer capacity for from binary system 122.45 64.68 mg/g Cd(II), respectively. kinetic studies exposed process followed nonlinear pseudo-first-order model. isotherm show extended Langmuir model more applicable than Freundlich process. value diffusion coefficient in range 10 −10 m 2 /s which indicates chemisorption nature maximum desorption 98.41% 97.66 utilized 0.3 M nitric acid. This indicated composite can be regenerated reused further wastewater.

Removal of Congo red from aqueous solutions using nano-Chitosan

It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...
