原理 镉在磷酸或硫酸介质中,经碘化钾络合,甲基异丁基甲酮(Methyl-iso-butyl ketone, MIBK)萃取后,经火焰原子化,并根据其特徵谱线的吸收强度定量。 仪器 1.原子吸收分光光度计
Principle Cadmium is complexed with potassium iodide and extracted with methyl-iso-butyl ketone (MIBK) in a phosphoric acid or sulfuric acid medium. The resulting product is flame-atomized and quantified based on the absorption intensity of its characteristic spectrum. Instrument 1. Atomic absorption spectrophotometer
