Abstract:

Clay particles with organo silane-modified surfaces are provided along with a process for their preparation. The silane-modified clay is relatively easily and reliably produced by reacting clay with a R-substituted halosilane (R being a hydrophobic group) in a polar solvent containing a tertiary amine. The produced silanized clay is stable over a wide range of storage and use conditions. Contacting processes for using the silane-modified clay to remove organic contaminants from aqueous media are also provided. After use, the silane-modified clay particles can be regenerated, treated and reused for such contaminant removal.
