“…Also, wider stretching bonds of Al-O-Al and Al-O are seen in 847.16 and 606.95 cm − 1 , respectively. As expected, coating nano γ-alumina with βcyclodextrin cause changes in the width of FT-IR peaks [20,[28][29][30].…”

Nano γ-alumina (γ-Al2O3) is widely used to adsorb heavy metals due to excellent properties such as high surface area, thermal stability, and high adsorption capacity. Due to poor adsorption of toxic metals on nano γ-Al2O3 surface, coating with β-cyclodextrin improves its adsorption efficiency. The aim of this study was to synthesize nano γ-Al2O3/β-cyclodextrin by co-precipitation method to be used for future study in Cd(II) removal. The Fourier Transmission Infrared (FT-IR) spectroscopy, X- ray powder Diffraction (XRD) and, Scanning Electron Microscope (SEM) were evaluated. The results of XRD and SEM showed nano γ-Al2O3/β-cyclodextrin with 20–30 nm. Also, synthesized nano γ-Al2O3/β-cyclodextrin had suitable structure for cadmium removal as water toxic metal.

“…Grządka in 2015 investigated the adsorption properties of γ-Al 2 O 3 /β-cyclodextrin in the presence of some surfactants such as CTAB, SDS, TX-405 and TX-100 [20]. The surfactants prevent the accumulation of nano γ-Al 2 O 3 and improve their properties by forming complex with β-cyclodextrin.…”

“…The intermolecular hydrogen bond and the crystalline structure of SS were broken and destroyed through the pregelatinization process in boiling water . During the immersion processes in the aqueous ZnSO 4 electrolyte, a large number of free Zn 2+ ions form coordination bonds with two adjacent hydroxyl groups in the fragmented SS to generate interconnected networks, which provide abundant ion transportation channels to facilitate Zn 2+ migration between the electrolyte and electrode. − SS and SS@Zn 2+ gel films were prepared to perform FTIR measurements to demonstrate the development of hydrogen bonds. FTIR spectra of the SS film and SS@Zn 2+ gel film were tested and are collected in Figure S5.…”

Dendrite growth, hydrogen evolution, and corrosion reactions of zinc (Zn) metal anodes deteriorate the cyclic performance and hinder the commercial application of high-safety aqueous Zn-ion batteries. Herein, a hydroxyl-rich starch (SS) layer is rationally constructed on Zn anodes (Zn@SS) through a facile coating process to tune the Zn electroplating homogeneity and reduce adverse reactions with the electrolyte. SS layers with strong chelating ability can in situ coordinate with Zn 2+ ions within the aqueous electrolyte and form ionic conductive gels, which can decrease the contact area, facilitate ion transportation from the ZnSO 4 electrolyte to the metallic Zn anodes, and regulate the plating behavior for Zn 2+ ions. Zn@SS symmetrical cells show a prolonged circulation of 3000 h at 2 mA cm −2 . Even at a large charge/discharge depth of 5 mAh cm −2 , Zn@SS symmetric cells can provide a long lifetime of 1000 h. Zn@SS-V 2 O 5 full cells can operate for 1000 cycles at 1 A g −1 . This article offers a novel approach for the surface protection of Zn metal anodes through the construction of dynamic ionic conductive gel layers and widens the applied field of renewable and biodegradable starch-based biomass materials.

In order to explore the optimal conditions for the adsorption of Cd2+ in serpentine, this paper studied the adsorption of simulated cadmium solutions with serpentine as an adsorbent. On the basis of a single factor experiment, four factors including the amount of serpentine, initial pH, the initial concentration of solutions, and adsorption time were selected as the influencing factors, and the adsorption quantity and adsorption rate of serpentine to Cd2+ were double response values using the Box–Behnken design. Response surface analyses were used to study the effects of four factors on the adsorption quantity and adsorption rate of serpentine on cadmium, and the interaction between various factors. The results showed that the optimum adsorption conditions were as follows: the amount of serpentine was 1%, the initial pH was 5.5, the initial solution concentration was 40.83 mg·L−1, and the adsorption time was 26.78 h. Under these conditions, the theoretical adsorption quantity and adsorption rate of serpentine to Cd2+ were 3.99 mg·g−1 and 95.24%, respectively. At the same time, after three repeated experiments, the actual adsorption quantity and adsorption rate of serpentine to Cd2+ were 3.91 mg·g−1 and 94.68%, respectively, and the theoretical value was similar to the actual value. Therefore, it was proved that the experimental design of the regression model is reliable, and it is feasible to use the response surface method to optimize the adsorption conditions of serpentine on Cd2+.
