| Abstract: | To measure the content of inorganic elements in Konjac flour produced in different regions,ICP-AES method was used to measure the contents of Na、Mg、Ca、K、Mo、Mn、Ni、Cr、Ba、Fe、Zn、Cu、Pb and Cd in two kinds of Konjac flour produced in Sichuan and Burma.The relative standard deviation and detection limit were in the range of 0.10%～2.63% and 0.1～4.9 μg/L respectively.Impacts of microwave digestion method and dry-ashing digestion on measuring results were compared. |
