流动注射分析技术研究磷抑制剂分解反应动力学

KINETIC STUDIES OF DECOMPOSITION REACTIONS OF PHOSPHO-INHIBITORS BY FIA

作者设计了微机控制的流动注射自动分析系统，用于研究磷系抑制剂的分解反应。给定条件下５种有机磷酸盐和六偏磷酸钠的分解反应为准一级反应。根据测定的准一级反应速度常数，较详细地探讨了各类磷抑制剂的分解条件。文中提供的流动注射自动分析系统可推广应用于测定其它中速液相反应的速度常数。

篈n automatic microcomputer-controlled FIA system was designed to study the decomposi-tion reactions of phospho- inhibitors． Under the experimental conditions，the decomposition reactions offive organic-phosphates and heptametaphosphate appeared to be approximately first order,Based on thedetermined pseudo first order reaction rate constants，the author explicitly discussed the decompositionconditions of various phospho-inhibitors，The proposed FIA system can be easily applied to the determi-nation the medium rate reaction constants of other systems .
