| Determination of Sodium in Acylglycerol by Atomic Absorption Spectrometry |
| CHEN Ming1; WU Zhen2（1. Testing Center of Hunan Research Institute of Chemical Industry; Changsha 410007; China; 2. Hunan Province Tobacco Quality Supervision and Test Station; China） |
| Abstract：Determination of the content of sodium in acylglycerol using atomic absorption spectrometry was described through selection of the sample dissolving time and solvent acidity,and comparison of the working curve method with standard addition method. The sample was dissolved with nitric acid under the heat condition,diluted and filtrated,and then determined by atomic absorption spectrometry. The sample dissolving time and acid had an effect on determination of the sodium content. RSD was 2.3%～2.8%,and recovery... |
