| 摘 要： | 碱性条件下,肉桂酸对Luminol-H2O2-纳米银化学发光体系有较强的增敏作用,据此,结合流动注射技术,建立了测定肉桂酸的新方法。该法线性范围为2.5×10-8～2.5×10-6mol/L,检出限为6.0×10-9mol/L,对1.0×10-7 mol/L的肉桂酸平行测定9次,相对标准偏差为2.5%。该法可用于尿液中肉桂酸的测定。

| Abstract: | A novel method for the determination of cinnamic acid was developed based on its enhancement effect on the luminol-H2O2-silver nanoparticles chemiluminescence system.Under the optimum conditions,the linear range for the determination of cinnamic acid was 2.5 × 10-8 to 2.5 × 10-6 mol/L with a detection limit of 6.0 × 10-9 mol/L,and the relative standard deviation was 2.5% for 1.0 × 10-7 mol/L cinnamic acid solution in nine repeated measurements.It was successfully applied to the determination of cinnamic acid in human urine. |
