%X 采用焦糖爆米花制备多孔生物质碳并用于修饰玻碳电极，提出了一种对硝基酚的电化学传感器。通过对比扫速、pH等的影响，探索最佳测试条件。在1~200 μM之间对硝基酚的浓度与峰电流线性相关，检测限为0.23 μM。相对于其他一些对硝基酚的传感器，检测限稍高，性能稍差。原因可能是与爆米花本身结构有关，部分纤维素不能通过后处理清除干净，导致其电化学响应较弱。<br />
A p-nitrophenol sensor (p-NP) was proposed by porous carbon materials (PCMPC) prepared from caramel popcorn. The optimal test conditions were investigated by comparing the effects of scanning rates, pH and so on. The lower detection limits were found to be 0.23 μM and the range of linear relationship was 1~200 μM. Compared with other p-nitrophenol sensors, its detection limit is higher and the performance is worse. It probably has something to do with the structure of the popcorn. Part of cellulose could not be cleaned by post-treatment, resulted in weak electrochemical response.
