Abstract:
Disclosed is a method of evaluating a final equilibrium pH of a contaminated soil on site by using a paste pH. The method includes measuring the paste pH by adding a solution to the contaminated soil, and evaluating the final equilibrium pH according to an initial pH by applying the paste pH to Final equilibrium pH = ( paste pH + 1 ) × exp ( - 1 initial pH ) - exp ( - 1 ( paste pH + 1 ) initital pH ) , Equation 1 in which the initial pH is a predetermined integer in a range of 1 to 10.
