摘要
基于在碱性介质中 Cr( )和 V( )对鲁米诺和过氧化氢的催化化学发光反应 ,研究了毛细管电泳在线化学发光分离和检测 Cr( )和 V( )。方法简便、快速、灵敏、进样量少。 Cr( )和 V( )的检出限分别为 7.8× 1 0 - 8mol/L和 5.0× 1 0 - 6mol/L ,线性范围分别是 32～ 80 ng/m L和 0 .55～ 3.0μg/m
A capillary electrophoresis chemiluminescence method was developed to determine both Cr(Ⅲ) and V(Ⅴ). The method was simple, rapid and had better detection limits. The linear calibrations for Cr(Ⅲ) and V(Ⅴ) were established over the concentration range of 32~80 ng/mL and 0.55~3.0 μg/mL with detection limits of 7.3×10 -8 mol/L and 5.0×10 -6 mol/L, respectively, by using 0.02 mol/L phosphate butter(pH=2.5).
