“…[19] Among this adsorbents, metal oxides, such as manganese dioxide, titanium dioxide and zinc oxide, have received enormous attention due to its availability, thermostability and environmental friendliness. [10,20] As a multifunctional and environmental friendly material, ZnO has been used for uranium (VI) adsorption. [21] Recently, Kaynar et al have prepared nanoporous ZnO for removal of uranium.…”

In situ growth of ZnO nanorod arrays on cotton cloth (ZnO/CC) was proposed to remove uranium (VI) from aqueous solution. The as-prepared adsorbent is easy separation from the reaction medium after adsorption. The effect factors for uranium adsorption, such as solution pH, initial U (VI) concentration, contact time, and temperature have been systematically investigated. The maximum adsorption capacity of uranium (VI) which was calculated by the Langmuir model at pH=5.0 and T=298 K is 431.03 mg g -1 , exhibiting its excellent uranium adsorption properties. It was observed that the kinetic data fit well to the pseudo-second-order kinetic model indicating that the rate-limiting step of adsorption process is chemical adsorption. Moreover, thermodynamic parameters [ΔH 0 =20.26 kJ mol -1 ΔG 0 =-5.66 kJ mol -1 (298 K) ΔS 0 =86.98 J mol -1 K -1 ] reveal that the uranium adsorption is endothermic and spontaneous. Therefore, the ZnO/CC is a potential adsorbent for recovery of uranium (VI) from aqueous solution.

“…Therefore, organic resins could not be used in the treatment of waste water of high radioactivity because of their low fusion point. 9 The reported chelating resin (PS-PAMAM-PPA) has a long gra chain for the adsorption of uranium. 10 The prepared silica modied by the (3-mercaptopropyl)-trimethoxysilane was used for application in nuclear environmental remediation.…”
