摘 要: | This paper described a novel method for the preconcentration of Pb(Ⅱ) using microcrystalline triphenylmethane loaded with quinolin-8-olate prior to the determination by flame atomic absorption spectrometry.Pb(Ⅱ) could be enriched by controlling appropriate condition.The preconcentration factor could reach to 200 and the detection limit of Pb(Ⅱ) was 0.074μg/L.The recovery was in a range of 93.5-103%with relative standard deviation of 1.0-2.2%.The proposed method had been successfully applied to the determ...
