酸性靛蓝-H2O2-OH-化学发光测定Cu(Ⅱ)的新体系
NEW CHEMILUMINESCENT SYSTEM INDIGO CARMINE-H2O2-OH-FOR THE DETERMINATION OF COPPER(Ⅱ)
【摘要】 本文拟定了酸性绽蓝-H2O2-OH-体系测定微量Cu(Ⅱ)的新化学发光分析法。该方法测定Cu(Ⅱ)的检测限为0.3μg/L,线性范围为10~200μg/L。三十余种共存离子中,Fe(Ⅲ)、Cr(Ⅲ)等离子对测定有干扰。
【Abstract】 A new method based an indigo carmine-H2O2-OH- chemiluminescent reaction for the detcrmination of trace Cu(Ⅰ)was reported. The detection limit for the determination of Cu(Ⅱ) is 0.31μg/L, the linear range of the calibration curve is from 10 to 200 μg/L Cu(Ⅱ). Among 30 foreign ions tested, Fe(Ⅱ)and Cr(Ⅱ)interfere with the determination.
