Are electrochemical fences effective in the retention of pollution?
10.1016/j.seppur.2018.02.040 2018-02-21 In this work, a three-month test is used to evaluate the role of electrokinetic fences in the prevention of the diffusion of herbicide in case of accidental spills of large amounts of highly concentrated products in clay soil. To do this, a mock-up (0.95x2.00... |
