RETRACTED: Effects of Bacillus subtilis on the reduction of U(VI) by nano-Fe0

The uptake of uranium by tea wastes investigated by batch, spectroscopic and modeling techniques

“…4 showed the adsorption isotherms of U(VI) on tea wastes at T = 298, 303 and 313 K. It was observed that the highest and lowest adsorptions were observed at T = 313 K and at T = 298 K, respectively, which indicated that high temperature was beneficial for U(VI) adsorption. The proportion and activity of U(VI) ions in solution increased with increasing temperature, which facilitated the coordination of U(VI) ions to functional groups of tea waste surface [39,40]. The adsorption data of U(VI) on tea waste at different temperatures were regressively simulated with the Langmuir [41] and Freundlich models [42].…”

Effect of Microbes on the Adsorption of Naphthalene by Graphene Oxide

“…The deconvolution of the C 1s peak of GO was shown in Figure 1(e). As illustrated in Figure 1(e), the main peaks at 284.7, 286.6, 287.9, and 289.8 eV were ascribed to the C-C, C-O, C=O, and O-C=O, respectively [27][28][29]. According to the XPS analysis, the contents of oxygen in GO and hydrogen were approximately 30.96 and 0.11 atomic %, respectively.…”

Adsorption and photocatalytic reduction activity of uranium(VI) on zinc oxide/rectorite composite enhanced with methanol as sacrificial organics

“…Second, the mesoporous structure and the large specific surface area of the ZnO/rectorite composite are in favor of the photocatalytic-reduction by adsorbing the U(VI) onto the surface and the interlayer of the silicate. Moreover, another essential requisite for the U(VI) photoreduction is the recombination of photogenerated electrons and holes can be effectively inhibited by rectorite [32][33][34], and then the intramolecular electron within ZnO-methanol complexes are efficiency transfer, resulted in the higher visible light photoreduction activity.…”
