Incazelo Yomkhiqizo:
Lo mkhiqizo uyinhlanganisela ye-multivalent. Ingasetshenziselwa ukuhlanganisa izinsimbi futhi iyi-ejenti eqinile yokuchela yama-ion ensimbi avamile. Kuyi-agent entsha ye-chelating esetshenziswe kuphela kusukela ngo-1953. Inzuzo yayo evelele kakhulu ikhono layo lokwakha amadiski e-chelate azinzile nge-Fe3 + kuzixazululo eziluhlaza ze-alkaline (pH = 8-11) nokwenza izihlanganisi ezizinzile ezinezinsimbi zomhlaba ezingavamile.
Isicelo:
(1) Ngaphezu kokusetshenziswa kwayo kumakhemikhali okuhlaziya, kancane kancane isetshenziswa ekusetshenzisweni okuhlukahlukene kwezindwangu, ezolimo (izibulala-zinambuzane, i-HEDTA-Fe yokuvundisa insimbi enhlabathini ene-alkali), umuthi (njengekhambi lobuthi bensimbi), isikhumba, iphepha, izimonyo, ukwelashwa kwamanzi, i-electroplating, i-chemical plating (ikakhulukazi ekufakweni kwesiliva), njll.
(2) Inezinhlelo zokusebenza ezibaluleke kakhulu ekucwengisweni nasekuhlanzweni kwe-dilute ten.
