Amfani
HEDP wani nau'in hana lalatawar cathodic ne. Idan aka kwatanta da phosphates marasa tsari, ana iya haɗa shi da sodium molybdate, silicate, gishirin zinc da co-polymer galibi azaman hana lalata sikelin wajen magance ruwan sanyaya mai zagaye, walƙiyar filin mai da ruwan boiler. Hakanan ana iya amfani da shi azaman sequestrant a cikin sabulun wanki da wakili mai rikitarwa da scour na ƙarfe a cikin electroplating.
Halaye
HEDP na iya cire haɗin zuwa ions biyar masu kyau ko marasa kyau kuma ya cire ion ɗin ƙarfe mai valent biyu a cikin ruwa. Don haka yana ɗaukar kyakkyawan tasirin hana sikelin. Wannan samfurin yana da ƙarfi akan zafin jiki mai yawa, oxidizing da ƙimar pH mai yawa. Yana nuna cikakken tasirin haɗin gwiwa da tasirin warwarewa yayin da ake haɗa shi da sauran masu hana lalata da masu hana sikelin.
