摘　　要：分别研究了Ｃｒ（Ⅲ）及Ｎｄ（Ⅲ）与铬天青Ｂ在酸性媒介染料染色条件下的配合情况．采用最大摩尔比法和连续变化法分别测定了Ｃｒ（Ⅲ）及Ｎｄ（Ⅲ）与铬天青Ｂ的配合比．利用分光光度法首次验证了以铬天青Ｂ为配位体条件下。he coordination process between Cr(Ⅲ), Nd (Ⅲ) and chromazurol B (CAB) was investigated under the conditon for afterchrome dyeing .The coordination numbers for Cr(Ⅲ)-CAB and Nd (Ⅲ)-CAB were also respectively determined using Molar ratio method as well as continuous variation method. The ion-exchange process in which Cr(Ⅲ) replaces Nd(Ⅲ) on the coordination position of CAN was spectrophotometrically confirmcd.
