阿司匹林对B-Z化学振荡体系的影响及其分析检测

摘要

在连续搅拌反应器(CSTR)中,研究了阿司匹林对封闭体系中 B-Z 振荡反应体系的影响.研究结果表明：阿司匹林溶液浓度在5.00×10-6~5.00×10-1 mol/L范围内,振荡反应的振幅变化值(ΔE)与阿司匹林浓度(c)的关系符合方程：ΔE=34.7 c 0.154,R2=0.999,最低检测限达10-6 mol/L.%Effects of aspirin on B-Z oscillating system in closed system were investigated in a continuous-flow stirred tank reactor (CSTR). The results showed that the relationship between the amplitude changing values (ΔE) of oscillating reactions and the aspirin concentration (c) was in accordance with the equation ΔE = 34.7 c 0.154 (R2=0.999) in the aspirin concentration range from 5.00×10-6 to 5.00×10-1 mol/L, the lowest detection limit was 10-6 mol/L.
