HEDP ke sethibela-mafome sa organophosphorus acid. E ka chelate ka li-ion tsa Fe, Cu, le Zn ho etsa metsoako e tsitsitseng ea chelating. E ka qhala thepa e nang le oxidized holim'a libaka tsena tsa tšepe. HEDP e bonts'a litlamorao tse ntle tsa ho thibela ho bola ha sekala le mafome tlas'a mocheso oa 250℃. HEDP E na le botsitso bo botle ba lik'hemik'hale tlas'a boleng bo phahameng ba pH, e thata ho hasoa ka metsi, 'me e thata ho bola tlas'a khanya e tloaelehileng le maemo a mocheso. Mamello ea eona ea oxidation ea asiti/alkali le chlorine e betere ho feta ea li-acid tse ling tsa organophosphorus (letsoai). HEDP e ka arabela le li-ion tsa tšepe tsamaisong ea metsi ho theha motsoako oa hexa-element chelating, haholo-holo ka li-ion tsa calcium. Ka hona, HEDP e na le litlamorao tse ntle tse khahlanong le boholo le tse bonahalang. Ha e hahiloe hammoho le lik'hemik'hale tse ling tsa kalafo ea metsi, e bontša litlamorao tse ntle tsa tšebelisano-'moho. Boemo bo tiileng ba HEDP ke phofo ea kristale, e loketseng ho sebelisoa mariha le libakeng tse batang. Ka lebaka la bohloeki ba eona bo phahameng, e ka sebelisoa e le sesebelisoa sa ho hloekisa masimong a elektroniki le joalo ka lintho tse eketsang lik'hemik'hale tsa letsatsi le letsatsi.
HEDP e sebelisoa e le thibelo ea sekala le ts'enyeho tsamaisong ea metsi a pholileng a potolohang, tšimo ea oli le liboiler tse nang le khatello e tlase masimong a kang motlakase, indasteri ea lik'hemik'hale, tšepe, manyolo, jj. Indastering e lohiloeng ka bobebe, HEDP e sebelisoa e le sesepa sa tšepe le se seng sa tšepe. Indastering ea ho daea, HEDP e sebelisoa e le sesebelisoa sa ho tsitsisa peroxide le ho lokisa dae; Ho electroplating e seng cyanide, HEDP e sebelisoa e le setlolo sa chelating. Tekanyo ea 1-10mg/L e khethoa e le sethibela-matla, 10-50mg/L e le sethibela-matla, le 1000-2000mg/L e le sesepa sa ho hlatsoa. Hangata, HEDP e sebelisoa hammoho le polycarboxylic acid.
