摘要
介绍了激光技术的原理,并把该技术应用于丁二烯中氧含量的检测中,在此基础上重点考察了该技术的应用性能,该技术测定氧含量线性范围0.03%～3%,相对标准偏差RSD=0.18%(c=0.501%,n=9);与常规的气相色谱法相比,该技术具有简单、分析速度快、重复性好、尤其是不损坏样品,可以实现在线连续检测等特点,已成功应用于工业丁二烯中氧含量的测定。
This paper introduces the principle of laser technology, it is applied to determination of oxygen in butadiene. Research for it＇s application effect. The linear range for the method is 0.03 %-3 %, and the relative standard deviation is RSD=0.18 %（c=0.501% ,n =9 ）. The technology is simple , rapid and better repeatability with no sample destroyed, it is also carried out in situ analysis.The proposed method has been successfully applied to the determination of oxygen in butadiene.
