摘要
研究了异丙醇-硫酸铵双水相体系中,PAR与Co^(2+)形成的配合物,及配合物在该体系中两相间的分配行为。结果表明,在室温下,Co^(2+)-PAR配合物萃取到异丙醇中,其最大吸收波长为512 nm,并且Co^(2+)在0.00~2.50μg·mL^(-1)呈线性关系,符合朗伯-比尔定律,相关系数为R^2=0.99047,表观摩尔系数?=6.9×10~4 L·mol^(-1)·cm^(-1)。
The complexes of PAR and Co^2＋ formation and the distribution of complexes in the system of isopropanol-ammonium sulfate aqueous two-phase system were studied. The results show that at room temperature, the maximum absorption wavelength of the Co^2＋-PAR complex is 512 nm, and the Co^2＋ is linear in 0.00-2.50 μg mL^-1, which accords with the Lambert-Bill law, the correlation coefficient is R^2=0.99047, and the table observation coefficient ？=6.9×10^4 L·mol^-1·^2＋.
