Abstract
This invention generally relates to processes for recovering solubilized noble metals from aqueous process streams, in particular, aqueous process streams generated in the preparation of an N-(phosphonomethyl)glycine product, for example, by noble metal-catalyzed oxidation of an N-(phosphonomethyl)iminodiacetic acid substrate. The process includes contacting the aqueous process stream with a noble metal adsorption media such as an ion exchange resin to remove solubilized noble metal from the process stream.
