  • Comparison of MGDA, GLDA, ASDA and EDTA

    Comparison of MGDA, GLDA, ASDA and EDTA

    MGDA, GLDA, ASDA and EDTA belong to amino carboxylic acid chelating agents with similar structure. MGDA: Alanine, N,N-bis(carboxymethyl)-, trisodium salt; Methylglycine N,N-diAcetic acid, trisodium salt;GLDA: L-Glutamic acid, N,N-bis(carboxymethyl)-, sodium salt (1:4); Glutamic acid N,N-diAcetic acid tetrasodium salt;ASDA: Aspartic acid, N,N-bis(carboxymethyl)-, tetrasodium salt; L-aspartic acid N, N-diAcetic acid tetrasodium salt; EDTA: Glycine, N,N’-1,2-ethanediylbis[N-(carboxymethyl)-;Ethylene diamine tetraAcetic acid;…
