利用集成热电极的微流控芯片进行了苯酚的检测,在优化条件下得到苯酚的线性方程为Y=37.49c+2.16×10-4,相关系数为R=0.9918,检出限为5×10-8mol/L。热电极提高了检测的灵敏度且改善了重现性。由于微芯片具有便携性好、成本低廉等优点,可用于野外及生产现场等苯酚的含量测定。

Phenol was detected by microfluidic chip with integrated hot electrode. Under the optimal conditions, the linear equation of phenol was Y = 37.49c + 2.16 × 10-4, the correlation coefficient was R = 0.9918, the detection limit was 5 × 10 -8mol / L. Hot electrodes increase the sensitivity of detection and improve reproducibility. As the microchip has the advantages of good portability and low cost, it can be used for the determination of the content of phenol in fields and production sites.
