Abstract
The present subject matter illustrates a zero-valent metal suspension in non-aqueous phase. The suspension comprises 41 wt. % of a plurality of zero-valent iron particles; 0.1 wt % of a surfactant; 36 wt. % of an oil; and 23 wt. % of a thickening agent.
Claims17
A method for treating contaminated soil and water, the method comprising:
- preparing a zero-valent metal suspension in a non-aqueous phase, wherein the zero-valent metal suspension consists of a liquid membrane formed of a thickening agent, a surfactant and a vegetable oil encapsulating zero-valent metal particles;
- and
- introducing the zero-valent metal suspension in the non-aqueous phase into the contaminated soil and water by delivering in-situ through-contamination pools, directly mixing with the contaminated soil and water, or creating a permeable reactive barrier in the contaminated soil and water.
