【摘要】：將等離子體的高活化性能與催化發(fā)光的傳感特性相結(jié)合,以成本低、合成簡(jiǎn)單的堿土金屬納米Mg O為傳感材料,構(gòu)建了基于低溫等離子體輔助的催化發(fā)光傳感器,用于乙烯的快速檢測(cè)。由于等離子體具有高活化性能,本方法的檢測(cè)溫度遠(yuǎn)低于傳統(tǒng)的催化發(fā)光檢測(cè)法的常用溫度(300~500℃),無(wú)需加熱裝置,在室溫下實(shí)現(xiàn)了對(duì)乙烯快速、靈敏的檢測(cè)。室溫(25℃)下,對(duì)乙烯的檢出限為37 ng/m L(30 ppm),線性范圍為112~4997 ng/m L(90~3998 ppm,R=0.97669),傳感器具有良好的選擇性和重現(xiàn)性。此傳感器制備簡(jiǎn)單、穩(wěn)定性高、低能耗、成本低,與傳統(tǒng)的氣體檢測(cè)方法相比具有良好的實(shí)用性和普適性,為開(kāi)發(fā)性能優(yōu)異的新型催化發(fā)光傳感器提供了策略。
[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，
