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.
Claims20
A method for treating contaminated soil and water, the method comprising:
- preparing a zero-valent metal suspension in a non-aqueous phase;
- 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.
A method for preparing a zero-valent metal suspension in a non-aqueous phase, the method comprising:
- mixing about 21-41 wt. % of a thickening agent with about 33-63 wt. % of a vegetable oil to prepare a non-aqueous solution;
- dissolving about 0.05-1 wt. % of a surfactant into the non-aqueous solution;
- and
- mixing about 0.05-45 wt. % of zero-valent metal particles into the non-aqueous solution to obtain a zero-valent metal suspension
