摘　　要：制备了一种纳米Sb_(2)SnO_(5)/MIL-53(Al)复合材料,用于构建痕量异丁醛的催化发光(CTL)传感器。对CTL的分析条件进行优化,在最佳条件下,该传感器对异丁醛的响应时间和恢复时间分别为2s和5s,在0.00500mg/L 20.0mg/L浓度范围内催化发光强度与异丁醛浓度具有良好的线性关系(R2=0.99857),检出限为1.5μg/L(S/N=3)相对标准偏差(RSD,n=7)为1.3%此传感器用于分析实际样品中异丁醛的含量获得了满意的回收率(86.0%-106%),RSD(n=5)为4.7%-9.7%结果表明基于Sb_(2)SnO_(5)/MIL-53(Al)的CTL选择性好、灵敏度高,在异丁醛的痕量分析和环境监测中具有应用潜力。A nano-Sb_(2)SnO_(5)/MIL-53(Al)composite was prepared and used to construct a catalytic luminescence(CTL)sensor for trace isobutyraldehyde in this study and the analysis conditions of CTL were optimized simultaneously.Under the optimal conditions,the sensor exhibited a response time of 2 seconds and a recovery time of 5 seconds for isobutyraldehyde.Within the concentration range of 0.00500 mg/L-20.0 mg/L,the catalytic luminescence intensity showed a good linear relationship with the concentration of isobutyraldehyde(R2=0.99857).The detection limit was 1.5μg/L(S/N=3)and the relative standard deviation(RSD,n=7)was 1.3%.The sensor was used to analyze the content of isobutyraldehyde in actual samples.Satisfactory recovery rate(86.0%-106%)and RSD(n=5)were obtained,ranging from4.7%-9.7%.The results showed that the developed method had good CTL selectivity and high sensitivity,suggesting potential application in trace analysis of isobutyraldehyde and environmental monitoring.
