  • Where can aqueous PBTC solution be obtained?
  • Aqueous PBTC solution can be obtained from various suppliers (from dedicated chemical distributors to specialty suppliers for the industrial applications).
  • What are the impurities of technical PBTC?
  • Already Armbruster et al. reported on the several impurities of technical PBTC, depending on the conditions during synthesis and workup. Contaminants comprise, among others, phosphorous acid, ortho-phosphoric acid, phosphonopropionic, and phosphonosuccinic acids.
  • Which phosphoric acid contaminants are present in PBTC solutions?
  • Contaminants comprise, among others, phosphorous acid, ortho-phosphoric acid, phosphonopropionic, and phosphonosuccinic acids. Therefore, PBTC solutions from three different suppliers have been tested for their purity.
  • Are HEDP and PBTC a trace substance?
  • In particular the nitrogen-free HEDP and PBTC are thus in a similar concentration range as trace substances typically found in European WWTPs such as acetaminophen, codeine, ibuprofen, naproxen, carbamazepine, and acesulfame, when present at high concentration levels .
