I-Diethylenetriaminepentamethylenephosphonic acid i-heptasodium usawoti, eyaziwa ngokuthi i-DETPMP•I-Na7, iyinhlanganisela esebenza kahle kakhulu ye-organic phosphonic acid-based.Umkhiqizo unefomula yamakhemikhali engu-C9H28N3O15P5Na7, i-molar mass engu-683.15 g/mol, futhi ibonisa ukusebenza okuhle kakhulu ezinhlelweni zokusebenza ezihlukahlukene.
Enye yezinzuzo eziyinhloko ze-DETPMP•I-Na7 iyisici sayo esihle kakhulu sokucwenga.Ingenza ama-complexes azinzile ane-ion ehlukahlukene yensimbi, ivimbele ngokuphumelelayo ukwakheka kwesikali, futhi isuse imiphumela emibi ye-ion yensimbi ohlelweni lwamanzi.Ukwengeza, umkhiqizo uvimbela ngokuphawulekayo ukugqwala ezindaweni zensimbi, okwenza kube ukukhetha okuhle kakhulu kokwelashwa kwamanzi okubhayela, amasistimu okupholisa amanzi ezimbonini, kanye nezicelo zenkundla kawoyela.
