| 摘 要： | 化学弛豫动力学是研究快速反应的一种重要手段［１］，特别适合于研究复杂的生物化学体系［２］．若某一反应体系在固定的外界条件下先期达到平衡，然后给该体系一个外（或内）参量跃变的扰动，使体系偏离平衡，体系经弛豫过程将达到新的平衡，用不同的检测方法可求出弛豫...

| Abstract: | A chemical relaxation kinetics analysis(CRKA) method has been proposed for the first time. The basic theory has been proved systematically and was applied to determine trace copper. Stopped-flow equipment was used for analyzing the system of Fe(Ⅲ)-S2O32- catalyzed by Cu(Ⅱ). We studied the influence of pH value, medium and reagent on relaxation parameter (1/τ) and obtained the linear relation of 1/τ and concentration. The analytical results of synthetic samples show that the CRKA method has an obvious advantage. |
