What method can be used to expose metals in soil into solution for analysis

Answer 1

One method that can be used to expose metals in soil into solution for analysis is the acid extraction method. In this method, soil samples are treated with a suitable acid, such as hydrochloric acid (HCl) or nitric acid (HNO3), in order to dissolve the metals present in the soil into solution. The acid helps to break down the soil matrix and solubilize the metals, allowing for their analysis by techniques such as atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS). The choice of acid and extraction conditions may vary depending on the specific metals of interest and the purpose of the analysis.
