Steward Environmental Solutions is part of the Steward group which has been manufacturing advanced magnetic powders for over 30 years. By combining the Steward powder expertise with the Battelle SAMMS technology, we are able to offer innovative adsorbent solutions for the collection of heavy metals. The Product advertised:polysciences.com The team who discovered and created it:samms.pnl.gov The SAMMS™ technology was originally developed for the U.S. Department of Energy, which has identified the separation and removal of mercury from the environment as a key technology need at its Oak Ridge Site. (BUT VERY IMPORTANTLY...) Preliminary screening tests for the adsorption of gold and silver show SAMMS can load more than 100 mg gold and 20 mg silver per gram of thiol-SAMMS™ under mild conditions. The gold-loading values are significantly greater than - activated carbon, a widely used adsorbent for the gold mining industry. Research has shown that this type of sorbent is very effective for recovering expensive catalyst metals, like Pt and Pd (Ind. Eng. Chem.. Res. 2004, 43, 1478-1484). The kinetics of Pd sorption are rapid, while Pt recovery is significantly slower (but nonetheless goes to completion). Further testing on the performance of thiol-SAMMS™ for precious metals is continuing. Additional data on selectivity, loadings, kinetics, and regeneration will be compared with ion exchange and activated carbon results. Specifics on Precious metal absorption:sammsadsorbents.com
