Patent number: 9678048Abstract: 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.Type: GrantFiled: February 14, 2014Date of Patent: June 13, 2017Assignee: KOREA INSTITUTE OF GEOSCIENCE AND MINERAL RESOURCESInventors: Pyeong-Koo Lee, Jung-Hae Choi
