1. A concentration agent comprising a particulate support selected from diatomaceous earth, metal oxide-modified diatomaceous earth, and combinations thereof, the particulate support bearing, on at least a portion of its surface, a surface treatment comprising titanium dioxide, fine-nanoscale gold or platinum, or a combination thereof, wherein when the surface treatment is fine-nanoscale gold or platinum or a combination thereof, at least a portion of the surface treatment has all dimensions in the range of up to 3 nanometers, wherein the concentration agent comprises a negative zeta potential when suspended in water. |
