| Abstract: | Objective] To get accurate analysis results, selection of container washing-up method is very important during heavy metal element analysis in soil. Method] The methods were used that polytetrafluoroethylene high-pressure microwave tube were dispelled by 5 ml guarantee reagent nitric acid and colorimetric cylinder were used 20% nitric acid by heat soaking, and heavy metals of standard substance in soil were used for verification test. Result] Many tests showed that those were good stability and precision and blank values were lower. Conclusion] This method could completely overcome the elements pollution problems, and reach better experimental requirements. |
