Optimization and Improvement of Detection Conditions for Potassium,Calcium and Magnesium in Plants by Hydrochloric Acid Extraction-AAS Method |
| |
| Abstract: | To optimize the detection conditions, hydrochloric acid extraction- AAS method was used to determine the content of potassium, calcium and magnesium under different conditions, such as different particle size, oscillation time, temperature, extraction methods and concentrations of hydrochloric acid. The results showed that sieving 60 mesh plant particles were suitable for hydrochloric acid leaching method, suitable oscillation time was 90 min with hydrochloric acid soaking at room temperature. With hot hydrochloric acid soaking, the temperature of hydrochloric acid was 55℃ and suitable oscillation time was 60 min. Proper concentration of hydrochloric acid was 1 mol/L. The proper method of hydrochloric acid leaching sample was oscillation. Hydrochloric acid extraction- AAS method established in this experiment was accurate and
efficient, economic and security, easy operation, it was suitable for inspection of batch sample. |
