Dump down the drain??? - I know a few people that would be choking on that idea. Save and label for disposal is my advice. How much do you expect to generate?

Subject: [DCHAS-L] HPLC solvent disposal
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?
