Process of inhibition oxalate scale formation
摘要:
A process of inhibiting oxalate scale formation in aqueous systems is disclosed. A preferred class of scale inhibitors is represented by polyamino hexamethylene phosphonates. These phosphonate inhibitors can be used in levels of from 0.05 ppm to 300 ppm (of the aqueous solution) at pH in the near neutral to preferably alkaline medium.
