本文报道的滤纸Delves杯火焰原子吸收法用于微量血铅分析,快速,灵敏。材料和方法直径8.2cm No903S&S滤纸。Delves杯,一端开口、一端封闭,3.5平方时的玻璃纸小口袋。110μl涂有肝素的毛细管。镀镍手动打孔器。SF-18-350无菌硅酮取样拭子。标准品和校准文献报道用原子吸收分光光度法测定时,血中铅和标准中铅的蒸汽化是不同的。相同量的铅其灵敏度因所用方法和基质的不同而异。这一现象称为基体效应。效应最小者为甲基异丁基酮(MIBK)萃取法,最大
The Paper reported Delves cup flame atomic absorption method for trace blood lead analysis, fast and sensitive. Materials and Methods Diameter 8.2cm No903S & S filter paper. Delves Cup, open at one end, closed at one end, 3.5 square cellophane pouch. 110 μl heparin coated capillaries. Nickel-plated manual hole puncher. SF-18-350 sterile silicone sampling swab. Standard and calibration literature reported by atomic absorption spectrophotometry, the blood lead and standard lead vaporization is different. The same amount of lead sensitivity varies with the method used and the substrate. This phenomenon is called the matrix effect. The least effect is methyl isobutyl ketone (MIBK) extraction method, the largest
