Te tūranga o ngā kaihoko chelating i roto i ngā hua horoi
Ko te Chelate, te chelate i hangaia e ngā kaihoko chelating, i ahu mai i te kupu Kariki ko Chele, arā, ko te maikuku pāpaka. He rite ngā Chelate ki ngā maikuku pāpaka e pupuri ana i ngā iona whakarewa, he tino pumau, he ngāwari hoki te tango, te whakamahi rānei i ēnei iona whakarewa. I te tau 1930, i hangaia te chelate tuatahi i Tiamana - EDTA (ethylenediamine tetraacetic acid) chelate hei rongoā i ngā tūroro e paihana ana i te konganuku taumaha, kātahi ka whakawhanakehia te chelate, ā, ka whakamahia ki te horoi matū o ia rā, ki te kai, ki te ahumahi me ētahi atu tono.
I tēnei wā, ko ngā kaihanga matua o ngā kaihoko chelating o te ao ko BASF, Norion, Dow, Dongxiao Biological, Shijiazhuang Jack me ētahi atu.
Ko te rohe o Āhia-Moana-nui-a-Kiwa te mākete nui rawa atu mō ngā kaihoko chelating, neke atu i te 50% o te hea, ā, e kiia ana ko te rahi o te mākete neke atu i te US $1 piriona, me ngā tono matua i roto i ngā ahumahi hopi horoi, maimoatanga wai, tiaki whaiaro, pepa, kai me te inu.
(Hanganga ngota o te kaiāwhina chelating EDTA)
Ka whakahaerehia e ngā ātete chelating ngā katote konganuku mā te chelating i ō rātou maha-ligands ki ngā matatini katote konganuku hei hanga chelates.
Mai i tēnei tikanga, ka taea te mārama he maha ngā ngota ngota he maha ngā ligand kei a rātou te kaha ki te chelation.
Ko tētahi o ngā mea tino kitea ko te EDTA i runga ake nei, e taea ai te whakarato i ngā ngota hauota e 2 me ngā ngota hāora carboxyl e 4 hei mahi tahi me te konganuku, ā, ka taea te whakamahi i te ngota kotahi hei takai pūmau i te katote konupūmā e hiahia ana kia 6 te taunga, ka puta he hua tino pumau me te kaha chelation tino pai. Ko ētahi atu chelator e whakamahia whānuitia ana ko te sodium phytate pērā i te sodium gluconate, te sodium glutamate diacetate tetrasodium (GLDA), ngā waikawa amino konutai pērā i te methylglycine diacetate trisodium (MGDA), me ngā polyphosphates me ngā polyamines.
E mōhio ana tātou katoa, ahakoa kei roto i te wai puna, i roto rānei i ngā wai tūturu, kei reira te konupūmā, te konupora, te rino plasma, ā, i roto i te wā roa ka whakarei ake i ēnei katote konganuku, ka pā mai ēnei pānga ki tō tātou oranga o ia rā:
1. Kāore te papanga i horoia tika, ka puta te unahi, ka whakapakeke, ka pōuri hoki.
2. Kāore he kai horoi e tika ana i runga i te mata mārō, ā, ka puta ngā putunga unahi
3. Whakaitihia ngā putunga i roto i ngā taputapu kai me ngā karāhe
Ko te pakeketanga o te wai e pā ana ki te nui o ngā iona konupūmā me te konupora i roto i te wai, ā, ka whakaitihia e te wai mārō te pānga horoi. I roto i ngā hua hopi horoi, ka taea e te matū chelating te tauhohe ki te konupūmā, te konupora me ētahi atu iona konganuku i roto i te wai, kia whakangawari ai te kounga o te wai, kia kore ai e tauhohe te konupūmā me te konupora plasma ki te matū hohe i roto i te hopi horoi, kia kore ai hoki e pā ki te pānga horoi, kia pai ake ai te whai huatanga o te hua horoi.
Hei tāpiritanga, ka taea hoki e ngā kaihoko chelating te whakau ake i te hanganga o te hopi horoi, ā, kāore e pirau ina werahia, ina rongoatia rānei mō te wā roa.
Mā te tāpiri i te kaitāpiri ki te hopi horoi kakahu ka taea te whakanui ake i tōna kaha horoi, inā koa i ngā wāhi e pāngia nuitia ana te pānga horoi e te pakeketanga, pērā i te raki, te tonga-māuru me ētahi atu wāhi he nui te pakeketanga o te wai, ka taea hoki e te kaitāpiri te ārai i ngā paru wai me ngā paru kei tau ki te mata o te kakahu, kia ngāwari ake ai te uru o te hopi horoi kakahu, kia ngāwari ake ai te piri ki te mata o te kakahu, kia pai ake ai te pānga horoi i te wā kotahi. Ka whakapai ake i te mā me te ngawari, kia kore ai e tino hina, e maroke hoki.
I roto anō i te horoinga o ngā mata mārō me ngā taputapu kai, ka taea e te kaihoko chelating i roto i te hopi horoi te whakapai ake i te kaha ki te whakarewa me te horapa o te hopi horoi, kia māmā ake ai te tango i te paru me te unahi, ā, ko te mahi ngāwari ko te kore e noho tonu te unahi, he mārama ake te mata, ā, kāore te karāhe e iri i te kiriata wai. Ka taea hoki e ngā kaihoko chelating te whakakotahi me te hāora i te rangi hei hanga i ngā matatini pumau e aukati ana i te waikura o ngā mata whakarewa.
Hei tāpiritanga, ka whakamahia hoki te pānga chelating o ngā āpiha chelating ki ngā katote rino i roto i ngā kaihoroi paipa hei tango i te waikura.
