Abstract
A flow-through spectrophotometric sensor for determination of copper based on retention of Cu(I)-1,2 ciclohexanedione thiosemicarbazone complex on C18 bonded phase beads packed in a flow-cell was developed. The method is highly selective for copper; it features a detection limit of 50 ng mL−1 and a linear range from at least 0.1 to 10 μg mL−1. The method is subject to very few interferences and is more sensitive than the batch procedure. The proposed method was applied to the determination of copper in catalysts and alloys. © 2000 John Wiley & Sons, Inc. Lab Robotics and Automation 12:241–245, 2000
用流动分光光度传感器测定痕量铜
建立了一种基于Cu(I)-1,2环己二酮硫代氨基脲配合物在流动池中C18键合相珠上的保留量测定铜的流动分光光度传感器。该方法对铜有很高的选择性;其检测限为50 ng mL - 1，线性范围至少为0.1至10 μg mL - 1。该方法受干扰很小，比批处理法更灵敏。该方法可用于催化剂和合金中铜的测定。©2000 John Wiley &儿子,Inc。实验室机器人与自动化，2000:241 - 245
