Heavy Metal Remediation Via Modified Bio-Oils

A process for the removal or extraction of metals, including heavy metals, precious metals and other metals, from a variety of solid, liquid or gas phase materials. Metal species are removed by contacting the material suspected of containing one or more metals with a fatty acid (or ester) for a period of time and under conditions effective for the sequestration of the metal species. The fatty acid or ester comprising of sequestered metal species is insoluble in water and may then be separated and recovered from the treated material.

Benefits

• Ability to conduct remediation in an environmentally friendly, bio-based manner
• Simplicity of process to localized contaminations such as spills, offers a broader range of markets
• Over 90% by weight of the metal species content, preferably 99% or more, can be removed from the material being treated

 

Applications

• Removal of toxic metals from contaminated drinking water and other fresh water systems (such as lakes, ponds, estuaries, rivers and streams
• Removal of toxic metals from waste discharge streams of agricultural, municipal sewage and from contaminated soil from agricultural
• Removal of toxic metals from industrial or mining sites and from flue gases discharged from commercial or industrial sites
