| Abstract: | Complexation of uranyl(II) and beryllium(II) ions with 2,2′-dimercaptodiethyl ether has been studied in 40% ethanolic media by potentiometric and conductometric titration techniques revealing the formation of an 1∶1 complex in either case. The stability constants of the complexes have been determined at ionic strength μ=0.1M (NaClO4) by applyingCalvin andMelchior's extension ofBjerrum's method. LogK stab values are found to be 12.60, 11.96 at 25 °C and 12.55, 11.90 at 35 °C respectively. The values of ΔG, ΔH and ΔS for the complexation reactions determined at 25 °C are also reported. |
