| Abstract: | Objective To establish a method for detecting food aluminum by inductively coupled plasma-atomic emission spectrophotometry.Method Pre-processing the samples by nitric acid-perchloric acid,and used inductively coupled plasma-atomic emission spectrophotometry to determination aluminum in food.Results The minimum detection limit of the method was 0.013mg/L,at the range of 0 to 1.0mg/L it showed linear relationship,coefficient correlation was r=0.99991,coefficient of recovery was at the range of 83.5% to 100.2... |
