Özet

In this study the effect of adsorption parameters such as pH, concentration of uranium(VI), shaking time, and temperature on methyl 3-O-acetyl-5,6-dideoxy- (S)-1,2-trichloroethylidene-α-d-xylo-hept-5(E)-eno-1,4-furano-uronate (MOADDTCEXHEFU) for U(VI) ions have been investigated. The adsorption data for uranium(VI) were well-fitted by the Langmuir isotherm. Thermodynamic analysis showed that the value of Go is negative and Ho and S o are positive. These results and a Fourier transform infrared (FTIR) spectrum analysis show that uranium(VI) ions were successfully bonded to this molecule. The affinity of MOADDTCEXHEFU to Th4+, Ba2+, and also Mg2+ is about 10 times higher than uranium(VI). © 2011 American Chemical Society.
