HEDPhe kai aukati waikura waikawa organophosphoric. Ka taea e ia te tarai me nga katote Fe, Cu, me te Zn hei hanga i nga pūhui chelating pūmau.HEDPe whakaatu ana i te pai o te tauine me te waikura i raro i te pāmahana 250 ℃.HEDPhe pai te pumau matū i raro i te uara pH teitei, he uaua ki te hauwai, he uaua ki te pirau i raro i nga tikanga marama me te wera. He pai ake te whakamaaramatanga o te waikawa/waikawa me te maaota i tera o etahi atu waikawa organophosphoric (tote).HEDPKa taea te tauhohe me nga katote whakarewa i roto i te punaha wai ki te hanga hexa-huānga chelating matatini, me te katote konupūmā. No reira,HEDPhe pai nga paanga o te paepae me te kitea. Ina hanga tahi me etahi atu matū maimoatanga wai, ka kitea nga hua pai o te whakakotahitanga. Te ahua totoka oHEDPhe paura tioata, he pai mo te whakamahi i nga waahi hotoke me nga waahi mīti. Na tona tino ma, ka taea te whakamahi hei kaihoko horoi i roto i nga mara hiko me nga taapiri i roto i nga matū o ia ra.
HEDPwhakamahia rite tauine me te waikura inhibition i roto i tohanga pūnaha wai matao, mara hinu, me te iti-pēhanga kōhua i roto i ngā mara pērā i te mana hiko, ahumahi matū, metallurgy, tongi, etc.. I roto i te ahumahi raranga marama,HEDPka whakamahia hei horoi mo te whakarewa me te kore konganuku. I roto i te ahumahi tae,HEDPka whakamahia hei whakapumau peroxide me te kaiwhakatika tae; I roto i te electroplating kore-cyanide,HEDPka whakamahia hei kaihoko chelating. Ko te inenga o te 1-10mg/L he pai ake hei aukati tauine, 10-50mg/L hei aukati waikura, me te 1000-2000mg/L hei horoi. Ko te tikanga,HEDPka whakamahia tahi me te waikawa polycarboxylic.
