| Abstract: |
| The sample was digested by microwave with Aqua and hydrofluoric acid, and multiple elements in Water-chilled dreg was determined by Inductively coupled plasma atomic emission spectroscopy. The sample can be dissolved completely in an airtight container at 185 °C for 60 Min, the interference of the composition of the digestion solution can be eliminated by selecting the appropriate spectrum line, the recovery rate is 95.72%～106.89%, the relative standard deviation is 0.68%～8.65% (N = 5) , the detection limit meet the analytical requirements。 The results show that the method is fast,simple and accurate,and the method can be used for the determination of multiple elements in Water-chilled dreg. |
