| Abstract: | The contents of aluminum(Al)in four kinds of wheat flour food(noodle,dumpling wrapper,twisted cruller and sodabiscuit)were determined by high resolution continuum source graphite furnace atomic absorption spectrometry(HR-CS GFAAS)combined with microwave digestion.The samples were completely digested by the mixture of HNO3and H2O2in closed polytet-rafluoroethylene(PTFE)vessels.The conditions for microwave digestion,pyrolysis temperature and atomization temperaturewere optimized.The optimum experimental condi... |
