Fe3O4磁性纳米粒子催化动力学荧光法测定微量过氧化氢
  • 摘要

    Fe3O4磁性纳米粒子(Fe3O4MNPs)具有模拟过氧化氢酶的催化特性.基于FeO4MNPs催化H2O2氧化吡罗红建立了催化动力学荧光法测定H2 O2的方法.对Fe3O4MNPs-吡罗红-H2O2体系的荧光光谱进行了研究,并考查了一些因素对体系的影响.所研究的催化反应分别在7~13min和13~18min内为假零级反应,对应的表观速率常数分别为1.33× 10-1 s-1和8.41×10-2s-1.反应时间为18 min时,催化反应的表观活化能为40.42 kJ·mol-1.在最佳实验条件下,方法的线性范围为3.20X10-4~1.12X10-2mol·L-1,检出限为1.65×10-4mol·L-1.该法可用于消毒液、雨水、自来水及合成样品中H2O2含量的测定.
