1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) — He Kaitiaki Whai Hua mō te Maimoatanga Wai Ahumahi

Ko te 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP), he matū matua tauine me te aukati waikura o te whānau waikawa phosphonic waro, kua noho hei matū pai mō te maimoatanga wai ahumahi me ngā tono maha-mara nā tōna hanganga matū pumau me te mahi tino pai. Ka tiakina te mahi roa o ngā taputapu me te whanaketanga whai hua o ngā ahumahi.

Ko ngā painga matua o te HEDP kei roto i te ātete ki te pāmahana teitei, te ātete ki te waikawa me te kawakore, me te kaha ki te whakapūmau. Ko tōna hanganga here CP ahurei ka ātete ki te waikura me te pupuri i te mahi pumau i raro i te pāmahana teitei tae atu ki te 250℃ me te whānuitanga pH whānui o te 2-12, me te ātete pai rawa atu ki te waikura chlorine ki te whakataurite ki ngā hua waikawa phosphonic waro rite. Ka taea e ngā rōpū waikawa bisphosphonic i roto i ōna ngota te hanga i ngā chelate mowhiti ono-mema pumau me ngā katote konganuku pēnei i te konupūmā, te konupūmā, te rino me te parahi, ka ārai pai i te hanganga o te unahi tae atu ki te konupūmā waro me te konupūmā whanariki. Ka tukuna e ia he pānga aukati unahi tino pai ahakoa i ngā kukū iti me te whai pānga paepae, me ngā pānga mahi tahi whakamiharo ina whakamahia i roto i ngā hanganga matū.

He whānui, he kanorau hoki ngā whakamahinga. I roto i te ahumahi, he whānui te whakamahinga i roto i te wai whakamatao e rere ana, i ngā kohua pēhanga reo me te iti, i ngā paipa weronga wai mara hinu me te tuku hinu i roto i te hiko, te matū, te whakarewa, te tongi matū me ētahi atu ahumahi, e ārai pai ana i te whakatakotoranga unahi me te waikura, e whakapai ake ana i te pai o te whakawhiti wera, ā, e whakaroa ana i te roa o te mahi a ngā taputapu. I roto i te ahumahi kakahu me te ahumahi māmā, he mea horoi whakarewa/kore-whakarewa, he mea whakaū peroxide me te mea whakatika tae mō te whakama me te tae. Hei tāpiri, ka taea te whakamahi hei mea whakakikorua hiko kore-cyanide, hei mea horoi parakore teitei mō te ahumahi hikohiko me te tāpiri mō ngā hua matū o ia rā. He iti te paitini me te atawhai taiao, ka tutuki i ngā hiahia o ngā āhuatanga rerekē.

Ko te whiriwhiri i te HEDP he whiriwhiri i tētahi otinga whai hua, pumau, ā, he iti te utu. Ka whakaoti i ngā raruraru o te tauine me te waikura me te mahi tino pai, ka whakaiti i ngā utu whakahaere me te tiaki, ā, ka āwhina i ngā pūnaha ahumahi ki te penapena pūngao me te whakaiti i te whakamahinga, ka waiho hei matū āwhina tino whai hua i roto i te hanga ahumahi hou.
