We have a research group that wants to begin a HPLC project using tetrafluoroacetic acid/acetonitrile mix (diluted to 40% in water) as the solvent. The student working on the project has used this procedure at another institution and said they dumped the waste solvent down the drain.. Really? I thought this would still have some characteristic hazard. Does anyone else have experience with this mixture, and how do you dispose of it properly?
