Determination of Lead in Red Wine by Different Pre-treatment Graphite Furnace Atomic Absorption Spectrometry
摘要
Abstract
Plum bum (Pb) determination in red wine by graphite furnace atomic absorption spectrometry (GF-AAS) was established through the research of pre-treatment method. The optimum conditions for determination of Pb in red wine were studied by five different pre-treatments. Result showed that the best matrix modifier agent was aseor-bic acid, its inhalation volume was 51μL. These pre-treatments were: direct dilution, evaporation concentration, H202-HNO3 digestion, HCIO4-HNO3 digestion and microwave digestion. The standard deviation was about 5% ; the microwave dispels RSD was 3.2%. This method is rapid and accurate and can be used in the detection of Pb.关键词
