| 摘 要： | 研究了脉冲辐解过程中氨基羟基脲与水辐解活性粒子（e-aq、·OH和·H）及单电子氧化剂·CO3-的反应动力学过程。反应近似为准一级反应，反应速率常数分别为k（e-aq）=1.41×108 L/(mol·s)、k（·OH）=1.05×1010 L/(mol·s)、k（·H）=2.68×105 L/(mol·s)、k（·CO-3）=4.25×108 L/(mol·s)。其中氨基羟基脲与·OH的反应速率常数最大，故在辐解过程中其为主要反应。

| Abstract: | The kinetics of reactions between hydroxysemicarbazide(HSC) with water-radioactive particles (e-aq, ·OH and ·H) as well as single electron oxidant ·CO-3 during pulse radiolysis were studied. The reactions are approximately quasi-first-order reactions, and the reaction rate constants are k（e-aq）=1.41×108 L/(mol·s), k（·OH）=1.05×1010 L/(mol·s), k（·H）=2.68×105 L/(mol·s), k（·CO-3）=4.25×108 L/(mol·s), respectively. Among them, the reaction rate constant of HSC and ·OH is the largest, so the reaction of HSC and ·OH is the main reaction during the pulse radiolysis process. |
