The Metal Testing Method. The soil reclamation and metal testing method for metals can be used in many situations where the results of an initial test result are inconclusive or extremely abnormal. This type of testing can be done with an ion exchange technique where the soil is mixed with a solution that has metallic ions replaced with an electrolyte. This is then passed through a magnetized gap to create an electric field that draws the metal ions from the soil and place them into an electrode where they are measured. If there is no reaction, then this is a good indicator that the metal ions have been pulled from the soil before any changes in the soil composition have occurred.

The standard soil testing extraction method used by most laboratories is a reverse osmosis process that relies on the separation of the water and the soil. The ion exchange technique on the other hand relies on the interaction of water and the metal ions for the removal process. It is important that you use only well tested, certified equipment when carrying out this process. The process used by soil testers relies on the method of electrical conductivity testing where the particular metal sample is weighed, mixed with a solution that contains solutions of sodium, potassium, and chloride. The weigh difference indicates the concentration of the metal content in the soil sample. Standard soil testing procedure is then followed to evaluate the results of the analysis results.

The non-destructive testing machines are different from the destructive ones. When the sample is being tested, the sample is placed into the device that has an electrical charge that will draw the sample into an electrode. There are different types of these devices depending on the amount of metals being tested. The thickness of the wire used is also important in determining the results of the test. The different types of electrodes are: electrochemical, electromagnetic, and optical.
