Infrared spectra were recorded for the EDTA chelates of Al(III), Ce(III), Bi(III), V(III), V (IV), Cr(III), Fe(III), Co(III), Ti(IV), Th(IV), Mo(V), and I(Mo(VI). The spectra, when related to previous studies, indicate that the bonding between ligand and metal ion is primarily ionic for the Al(III), Ce(III), and Bi(III) chelates, and primarily covalent for the remainder of the chelates. Correlations
记录了 Al(III)、Ce(III)、Bi(III)、V(III)、V(IV)、Cr(III)、Fe(III)、Co(III)、Ti 的 EDTA 螯合物的红外光谱(IV)、Th(IV)、Mo(V) 和 I(Mo(VI)。与之前的研究相关的光谱表明,对于 Al(III),配体和金属离子之间的键合主要是离子键, Ce(III) 和 Bi(III) 螯合物,并且主要与其余螯合物共价。在各种官能团及其产生的吸收峰之间建立了相关性。合成并分离了这组金属离子的 EDTA 螯合物。 (授权)
