Abstract
(1-x)ZnO–xNiO nanocomposites (where x = 0.05, 0.10, 0.15 and 0.20) have been successfully synthesized using a mechanical mixing approach. Structural phase, morphological, and elemental composition analysis have been carried out using X-ray diffraction, scanning electron microscope, EDX, and XPS analysis. The systematic batch mode adsorption studies were carried out to evaluate the optimized adsorption behavior of synthesized nanocomposites (pH = 6; contact time = 90 min and adsorption dose = 0.5 g/L). Kinetic studies revealed that the prepared nanocomposite (0.80ZnO0.20NiO) successfully adsorbs U(VI) through a chemisorption nature with the maximum Langmuir capacity (~ 151.20 mg/g). The results demonstrated that the prepared 0.80ZnO0.20NiO can be used as a packaging material for column units in water purifiers.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
