HEDP Cas 2809-21-4 Waikawa Etidronic Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Waikawa (HEDP)
Nama CAS: 2809-21-4
Tātai ngota: C2H8O7P2
Whakamahia
He momo aukati waikura katote te HEDP. Ki te whakatauritea ki ngā phosphates inorganic, ka taea te whakakotahi ki te konutai molybdate, te silicate, te tote konutea me te co-polymer hei aukati waikura tauine i roto i te maimoatanga o te wai whakamatao huringa, te mura o te mara hinu me te wai kohua. Ka taea hoki te whakamahi hei sequestrant i roto i te hopi me te kaihoko matatini me te horoi whakarewa i roto i te whakakikorua hiko.
Āhuatanga
Ka taea e te HEDP te wetewete i te hononga ki ngā katote e rima pai, kino rānei, ka whakakōpiri i te katote whakarewa rua-valent i roto i te wai. Nō reira, he pai te pānga aukati tauine. He ātete tēnei hua ki te pāmahana teitei, te waikura me te uara pH teitei. E whakaatu ana i te pānga mahi tahi tino pai me te pānga paepae whakaoti i te wā e honoa ana ki ētahi atu aukati waikura me ngā aukati tauine.
