Amfani
Wannan samfurin shine babban kayan da ake amfani da shi wajen samar da wutar lantarki ba tare da cyanide ba. Lokacin da aka ƙera shi a matsayin maganin wutar lantarki ba tare da cyanide ba, yana da ƙarfin haɗin kai mai kyau lokacin da aka yi amfani da shi kai tsaye a kan ƙarfen sodium. Rufin yana da santsi kuma yana da kyakkyawan sheƙi. Gabaɗaya, yawan samfurin da ke cikin kashi 60% shine 100 - 120 ml/L. Yawan jan ƙarfe sulfate shine 15 - 20 g/L. Bugu da ƙari, kafin a samar da wutar lantarki, a nutsar da sassan farantin a cikin maganin 1% - 2% na wannan samfurin don sa sassan farantin su zama yanayin aiki. Yin amfani da wutar lantarki bayan wannan matakin na iya ƙara inganta tasirin. Hydroxyethylidene diphosphonic acid (HEDP) sabon nau'in maganin wutar lantarki ba tare da chlorine ba ne. Ana amfani da shi azaman babban wakili don daidaita ingancin ruwa a cikin tsarin ruwan sanyaya mai yawo, yana taka rawar hana tsatsa da hana sikelin. Wannan samfurin yana ɗaya daga cikin magungunan maganin ruwa na polyphosphonic acid na halitta. Akwai kuma wasu nau'ikan irin waɗannan samfuran da ake samarwa a China, kamar amino trimethylene phosphonic acid (ATMP): [CH2PO(OH)2]3N, da ethylenediamine tetra(methylene phosphonic acid) (EDTMP), da sauransu. An ƙirƙiri sinadaran polyphosphonic na halitta a ƙarshen shekarun 1960 kuma an gane su a kusa da shekarun 1970. Bayyanar wannan nau'in magungunan magance ruwa ya sami ci gaba a fasahar magance ruwa ta hanya mai girma. Idan aka kwatanta da polyphosphates marasa tsari, sinadaran polyphosphonic na halitta suna da kyakkyawan kwanciyar hankali na sinadarai, ba su da sauƙin hydrolyze, suna iya jure yanayin zafi mai yawa, suna buƙatar ƙaramin adadin maganin, kuma suna da halayen lalata da hana sikelin. Su nau'in masu hana lalata cathodic ne kuma wani nau'in masu hana sikelin stoichiometric ne. Idan aka yi amfani da su tare da sauran magungunan magance ruwa, suna nuna kyakkyawan tasirin haɗin gwiwa. Suna da kyakkyawan ikon chelating ga ions na ƙarfe da yawa kamar calcium, magnesium, jan ƙarfe, da zinc. Har ma suna da kyakkyawan tasirin kashe ƙwayoyin cuta a kan gishirin da ba na halitta ba na waɗannan ƙarfe, kamar CaSO4, CaCO3, MgSiO3, da sauransu. Saboda haka, ana amfani da su sosai a fasahar sarrafa ruwa. Ana amfani da sinadaran phosphorylating don kare serine da pyranose.
