Chelate, chelate ikorwa na chelating agent, ikomoka ku ijambo ry'ikigereki Chele, risobanura inzara.Chelates ni nkibikona byikona bifata ibyuma bya ion, bihamye cyane kandi byoroshye kuvanaho cyangwa gukoresha ibyo byuma.Mu 1930, chelate ya mbere yashizwe mu Budage - EDTA (Ethylenediamine tetraacetic aside) chelate yo kuvura abarwayi bafite uburozi bw’ibyuma biremereye, hanyuma chelate ikorwa kandi ikoreshwa mu koza imiti ya buri munsi, ibiryo, inganda n’ibindi bikorwa.
Kugeza ubu, abakora inganda zikomeye za chelating ku isi barimo BASF, Norion, Dow, Biologiya ya Dongxiao, Shijiazhuang Jack nibindi.
Agace ka Aziya-Pasifika nisoko rinini ryogukora chelating, rifite imigabane irenga 50% hamwe n’isoko ryagereranijwe rirenga miliyari imwe y’amadolari y’Amerika, hamwe n’ibikorwa rusange bikoreshwa mu gukaraba, gutunganya amazi, kwita ku muntu, impapuro, ibiryo n'ibinyobwa .
(Imiterere ya molekulari ya chelating agent EDTA)
Ibikoresho bya chelating bigenzura ioni mugukata ligande nyinshi hamwe nibyuma bya ion kugirango bibe chelates.
Duhereye kuri ubu buryo, birashobora kumvikana ko molekile nyinshi zifite ligande nyinshi zifite ubushobozi bwa chelation.
Kimwe mubisanzwe ni EDTA yavuzwe haruguru, ishobora gutanga atome 2 za azote na atome 4 za ogisijeni ya karubisi kugirango ifatanye nicyuma, kandi irashobora gukoresha molekile 1 kugirango ipfundike cyane ion ya calcium ikenera guhuza 6, ikabyara ibicuruzwa bihamye cyane kandi byiza ubushobozi bwa chelation.Izindi chelator zikunze gukoreshwa zirimo sodium phytate nka sodium gluconate, sodium glutamate diacetate tetrasodium (GLDA), acide sodium amino nka methylglycine diacetate trisodium (MGDA), na polyphosifati na polyamine.
Nkuko twese tubizi, haba mumazi ya robine cyangwa mumazi asanzwe, hariho calcium, magnesium, plasma yicyuma, izo ion zicyuma mugutunga igihe kirekire, bizazana ingaruka zikurikira mubuzima bwacu bwa buri munsi:
1. Umwenda ntusukurwa neza, utera igipimo kinini, gukomera no kwijimye.
2. Nta kintu cyogukora isuku kiboneka hejuru, hamwe nububiko
3. Kubitsa umunzani mubikoresho byo kumeza no mubirahure
Gukomera kwamazi bivuga ibiri muri calcium na magnesium ion mumazi, kandi amazi akomeye azagabanya ingaruka zo gukaraba.Mu bicuruzwa byangiza, imiti ya chelating irashobora kwitwara hamwe na calcium, magnesium nizindi ion zicyuma mumazi, kugirango yoroshe ubwiza bwamazi, irinde calcium na magnesium plasma kutagira icyo ikora hamwe na agent ikora mumashanyarazi, kandi ikirinda kugira ingaruka kumesa. , bityo kuzamura imikorere yibicuruzwa.
Byongeye kandi, imiti ya chelating irashobora kandi gutuma ibice byogeramo bihagarara neza kandi ntibishobora kwangirika iyo bishyushye cyangwa bibitswe igihe kirekire.
Kwiyongera kwa chelating agent kumesa yo kumesa birashobora kongera imbaraga zogusukura, cyane cyane mubice aho ingaruka zo gukaraba zibasirwa cyane nubukomere, nkamajyaruguru, amajyepfo yuburengerazuba ndetse n’utundi turere dufite amazi menshi, imiti ya chelating irashobora kandi kwirinda kwanduza amazi no kwanduza. kuva gutura hejuru yigitambara, kugirango imyenda yo kumesa irusheho kwemerwa kandi byoroshye gufatirwa hejuru yimyenda, kunoza ingaruka zo gukaraba icyarimwe.Kunoza umweru nubwitonzi, imikorere yintiti ntabwo ari imvi kandi yumye cyane.
Na none mugusukura cyane hejuru no gusukura ibikoresho byo kumeza, chelating agent muri detergent irashobora kunoza ubushobozi bwo gusesa no gutatanya ibikoresho, kugirango irangi nubunini byoroshye kuvanaho, kandi imikorere yintiti ni uko igipimo kidashobora kuguma, hejuru iragaragara cyane, kandi ikirahure ntikimanika firime.Imiti ya chelating irashobora kandi guhuza hamwe na ogisijeni mu kirere kugirango ibe inganda zihamye zibuza okiside hejuru yicyuma.
Byongeye kandi, ingaruka zo gukonjesha ibintu bya chelating kuri ion zicyuma nazo zikoreshwa mugusukura imiyoboro kugirango ikureho ingese.
