英语释义

1. a white crystalline acid C10H16N2O8 that is widely used as a chelating and sequestering (see sequester entry 1 sense 3) agent especially to inhibit the reactivity of metal ions Note: In addition to industrial and scientific applications, EDTA is used as a food additive to preserve foods and inhibit discoloration. It is also used in medicine especially in chelation therapy to treat lead poisoning. EDTA is typically used in the form of a salt (such as the disodium salt C10H14N2O8Na2·2H2O or the calcium disodium salt C10H12N2O8Na2·3H2O).

2. a white crystalline acid C10H16N2O8 used in medicine as an anticoagulant and as a chelator in the treatment of lead poisoning — called also ethylenediaminetetraacetic acid
