发明名称 Recovery of noble metals from aqueous process streams
摘要 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.
