| 摘要 |
The present invention relates to methods for the preparation and analysis of soil samples to determine the presence, concentration and/or volume of at least one component in a soil sample, including preparation steps of extracting the component from the sample by use of aqueous solution and, depending on the element, adding a complexing agent to the aqueous solution and soil mixture. The resulting mixture is then able to be analysed via NIR or UV/Vis spectrometry as the component, not normally detectable via NIR or UV/Vis spectrometry, is converted into an accurately measurable form. The methods of the present invention may be used to obtain a test results on site and within a time period of 10 to 45 minutes rather than a time period of days using present methods. |
