摘　　要：测定了稀土铒盐与甘氨酸(Gly),组氨酸(L-His),脯氨酸(L-Pro)形成配合物的紫外光谱并研究了其离解动力学,实验表明:配合物在模拟生理条件下的离解完全符合一级反应动力学规律;pH=4时,稀土脯氨酸配合物离解速度较快,而稀土甘氨酸、组氨酸配合物不发生离解.The UV spectra of erbium salt with glycine （Gly）, histidine （L- His） and proline （L - Pro） was determined, and its dissociation kinetics was studied. The experiment shows that its dissociation was conformed to the first - order reaction kinetics rule completely under simulation physiology condition. The fastest dissociation velocity of rare earth complexes with proline was at.pH = 4. But the rare earth complexes with both proline and glycine did not dissociation.
