Ukucaciswa komkhiqizo:
| Into | I-EDTA(Ethylenediaminetetraacetic acid) |
| Okuqukethwe (%)≥ | 99.0 |
| I-Chloride (njenge-Cl) (%)≤ | 0.01 |
| I-Sulphate (njenge-SO4)(%)≤ | 0.05 |
| Izinsimbi ezinzima (njenge-Pb)(%)≤ | 0.001 |
| I-ayina (njengo-Fe)(%)≤ | 0.001 |
| Inani le-Chelation: mgCaCO3/g ≥ | 339 |
| PH inani | 2.8-3.0 |
| Ukubukeka | I-crystalline powder emhlophe |
Incazelo Yomkhiqizo:
Impushana emhlophe ecwebezelayo, indawo encibilikayo engu-240°C (ukubola). Ayincibiliki emanzini abandayo, utshwala nezincibilikisi ezijwayelekile zemvelo, zincibilika kancane emanzini ashisayo, zincibilika ezixazululweni ze-sodium hydroxide, i-sodium carbonate ne-ammonia.
Isicelo:
(1) Isetshenziswa njengesixazululo sokuhlanza nokulungisa ukucutshungulwa kwezinto ezithwebula izithombe ezinemibala, izinsiza zokudaya, izinsiza zokwelapha ifayibha, izithasiselo zezimonyo, ama-anticoagulants egazi, okokuhlanza, okokuqinisa, iziqalisi zenjoloba zokwenziwa ze-polymerisation, i-EDTA iyinto emele ama-chelating agents.
(2) Ingakha izakhiwo ezinzile ezincibilika emanzini ezinezinsimbi zomhlaba ezine-alkali, izakhi zomhlaba ezingavamile kanye nezinsimbi eziguqukayo. Ngaphezu kosawoti we-sodium, kukhona nosawoti we-ammonium nensimbi, i-magnesium, i-calcium, ithusi, i-manganese, i-zinc, i-cobalt, i-aluminium kanye namanye ama-salts ahlukahlukene, ngayinye yalawa sawoti inokusetshenziswa okuhlukile.
(3) I-EDTA ingase futhi isetshenziselwe ukukhipha ubuthi ezinsimbini ezinemisebe eyingozi emzimbeni womuntu ngenqubo yokukhipha ngokushesha. Ibuye isetshenziswe njenge-ejenti yokwelapha amanzi.
(4) I-EDTA iyinkomba ebalulekile futhi ingasetshenziselwa ukuhlanganisa i-nickel, ithusi, njll. Kufanele isetshenziswe kanye ne-ammonia ukuze isebenze njengenkomba.
