[Objective] The study aimed to establish a method for simultaneous determination on As and Bi in Ganoderma lucidum samples by sequential injection hydride generation-atomic fluorescence spectrometry.[Method] G.lucidum samples were digested by microwave rapid digestion system and the contents of As and Bi in each sample were determined by atomic fluorescence spectrometer based on the drawn standard curve.The effects of the factors such as the negative high voltage on the photomultiplier,lamp current of As an...
