Fabrication of chitosan-alginate-polyvinylpyrrolidone for efficient removal of Cr(VI) from wastewater in experiment and adsorption mechanism
This study synthesized chitosan-alginate-polyvinylpyrrolidone and applied it for Cr(VI) removal. Characterization was carried out using FTIR, TGA, N2 adsorption, 1H NMR, and FE-SEM. FTIR spectra show peaks at 1415 cm− 1, 1323 cm− 1, 1029 cm− 1, and 448 cm− 1, which are COO, C-N, C-O, and N-C = O groups. The surface area of CsAgPVP was 20.42 m2/g. The pore size of CsAgPVP was 5.36 nm. Field emission shows the C, O, N, and Na. The optimum conditions CsAgPVP dor adsorption Cr(VI) were 50 ppm, 360 min, and pH 4. It uses adsorption isotherm and kinetic to show the Langmuir model and pseudo-second-order. The CsAgPVP adsorption process is assumed homogeneous and considered as chemisorption. Adsorption capacity shows 208.67 mg/g. It uses a regeneration study of removal percentage up to 90% in the fourth cycle. The removal percentage in real sample mine wastewater and waste acid laboratories was 80% and 72%.
期刊介绍：
The journal Adsorption provides authoritative information on adsorption and allied fields to scientists, engineers, and technologists throughout the world. The information takes the form of peer-reviewed articles, R&D notes, topical review papers, tutorial papers, book reviews, meeting announcements, and news.
Coverage includes fundamental and practical aspects of adsorption: mathematics, thermodynamics, chemistry, and physics, as well as processes, applications, models engineering, and equipment design.
Among the topics are Adsorbents: new materials, new synthesis techniques, characterization of structure and properties, and applications; Equilibria: novel theories or semi-empirical models, experimental data, and new measurement methods; Kinetics: new models, experimental data, and measurement methods. Processes: chemical, biochemical, environmental, and other applications, purification or bulk separation, fixed bed or moving bed systems, simulations, experiments, and design procedures.
