I-Trisodium (2-hydroxyethyl) ethylenediaminetriacetate |139-89-9
Ukucaciswa komkhiqizo:
| Into | I-Trisodium (2-hydroxyethyl) ethylenediaminetriacetate |
| Okuqukethwe (%) Ukuhlanzeka≥ | 39.0 |
| Ukuminyana | 1.26-1.31 |
| I-Chromaticity ≤ | 300 |
| Inani le-Chelation ≥ | 120 |
| PH | 11.0-12.0 |
| I-Chloride (njenge-CL) (%) ≤ | 0.01 |
| I-Sulphate (njenge-SO4) (%) ≤ | 0.05 |
| Izinsimbi ezinzima (Pb) (%) ≤ | 0.001 |
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.
