1-hydroxyethylidene-1,1-disphosphonic waikawa (hedp)
Cas Kore: 2809-21-4
He tātai molecular: C2H8O7P2
Whakamahi
Ko te HeDP he momo momo o te Katorika cahodic. I whakaritea ki te phosphates Inorgatic, ka taea te whakahiato i te konutai i te konutai, te tote zinc, te waihini hinu me te waikawa wai. kaihoko matatini me te whiu whakarewa i roto i te electroplating.
Tā te tikanga
Ka raru pea a HedP ki te rima o nga katote he pai, he kino ranei, ka taea te tarai i te ion whakarewa e rua i roto i te wai. Ko te kupu ka pai te aukati i te paanga. Ko tenei hua he tohu ki te pāmahana nui, te hāora hāora. E whakaatu ana i te tino huanga me te whakaoti i te paanga o te paepae i te wa e whakahiatohia ana me etahi atu whakarakoni aukati me nga kainoho.
