Bismuthiol I이 내포된 p-Dicholorobenzene 미세결정으로 예비농축한 후 Copper(II) 정량 = Determination of Copper(II) after Preconcentration onto Microcrystalline p-Dichlorobenzene loaded with bismuthiol I

다국어 초록 (Multilingual Abstract)

A column preconcentration method with p-dichlorobenzene loaded with bismuthiol I (BI) was developed for the determination of trace Cu(II) in various aqueous samples by flame atomic absorption spectrophotometry. Several experimental conditions such as the pH of the sample solution, the amount of chelating agent bismuthiol I, the amount of adsorbent p-dichlorobenzene-BI, and the flow rate of sample solution were optimized. When the interfering effects of various concomitant ions were investigated, Bi(III) and Sn(II) interfered with. The dynamic range, the correlation coefficient (R2) and the detection limit of Cu(II) obtained by this proposed technique were 3.0~120 ng mL-1, 0.9913 and 1.6 ng mL-1, respectively. For validating this technique, the aqueous samples (wastewater, reservoir water and stream water) were used. Recovery yields of 95~98% were obtained. Based on the experimental results, it was found that this proposed technique could be applied to the determination of Cu(II) in various aqueous samples.
