Abstract
A technique on the determination of Co(II) in aqueous samples with quinalizarin-β-cyclodextrin inclusion complex was developed. The conditions such as pH of the sample solution, the concentration of quinalizarin and the concentration of β-CD were optimized to 11.3(±0.2), 1.2×10−6 M and 8.0×10−6 M, respectively. Under these optimum conditions, the calibration curve of Co(II) was obtained over concentration range of 5.0×10−9 ~ 1.2×10−7 M. The detection limit was 4.2×10−9 M (0.25 ng/mL). For validating this proposed technique, aqueous samples(stream water, reservoir water and tap water) were used. Recovery yields of 95~105% were obtained. The relative standard deviation(%) in aqueous samples were less than 7.0%. Based on experimental results, it is proposed that this technique can be applied to the practical determination of Co(II).
