Introduction of fuel hydrocarbons and inorganic compounds (heavy metals) into the soil,
resulting in a change of the soil quality, which is likely to affect use of the soil or endangering
public health and ground water. This study aimed to determine a series of parameters to
remediation of TPH and heavy metals contaminated soil by non-ionic surfactants-chelating
agents washing process. In this experimental study, the effects of soil washing time, agitation
speed, concentration of surfactant, chelating agent and pH on the removal efficiency were …
