【摘要】：将等离子体的高活化性能与催化发光的传感特性相结合,以成本低、合成简单的碱土金属纳米Mg O为传感材料,构建了基于低温等离子体辅助的催化发光传感器,用于乙烯的快速检测。由于等离子体具有高活化性能,本方法的检测温度远低于传统的催化发光检测法的常用温度(300~500℃),无需加热装置,在室温下实现了对乙烯快速、灵敏的检测。室温(25℃)下,对乙烯的检出限为37 ng/m L(30 ppm),线性范围为112~4997 ng/m L(90~3998 ppm,R=0.97669),传感器具有良好的选择性和重现性。此传感器制备简单、稳定性高、低能耗、成本低,与传统的气体检测方法相比具有良好的实用性和普适性,为开发性能优异的新型催化发光传感器提供了策略。
[Abstract]:By combining the high activation performance of plasma with the sensing characteristics of catalytic luminescence, a low temperature plasma-assisted catalytic luminescence sensor was constructed based on the synthesis of simple alkaline earth metal nano-MgO as sensing material with low cost. For rapid detection of ethylene. Due to the high activation performance of plasma, the detection temperature of this method is much lower than that of conventional catalytic luminescence detection method, which is 300 ~ 500 鈩，
