【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...更多还原

【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) S 2O 2- 3 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.更多还原
