Thiol-SAMMS ® * (Self Assembled Monolayers on Mesoporous Support) is a<br />
silica based “precious metal” recovery system for heavy metal scavenging<br />
of heterogeneous or homogeneous catalysts in API synthesis . Molecularly<br />
engineered mesoporous functionalized silica has the unique ability to bind<br />
palladium and other precious metals . The high surface area and functional<br />
thiol binding sites give the Thiol-SAMMS ® tremendous capacity and kinetics<br />
to absorb such metals very quickly in catalyzed reactions .<br />
Technical Data Sheet #782<br />
Advantages of Thiol-SAMMS ® technology:<br />
• Adsorption of 99% of targeted metals in minutes<br />
• Capacity up to 60% of SAMMS weight<br />
• Operational over a wide pH range (pH 2-12)<br />
• Meets the requirements of TCLP (EPA Toxicity Characteristic Leaching Procedure)<br />
• Allows for the reclamation of metals and adsorbents<br />
Features of Thiol-SAMMS ® technology vs. competitive systems including:<br />
• Superior scavenging for a range of metals such as Pd, Pt, Rh, Ru, Au, Ag,Cu, Cd, Hg & Pb<br />
• Metals may be in colloidal form, oxidized or zero - valent<br />
• Solvent compatible for homogeneous catalysts<br />
• Controlled pore size structures with high specific surface area<br />
• Excellent filtration behavior<br />
• High thermal stability with excellent thermal and structural stability<br />
• Thiol-SAMMS ® may be used in batch mode or fixed bed mode<br />
• Available as a test kit for quick sample evaluations and bulk quantities<br />
• Cost effective compared to alternative commercial technologies<br />
