近年来,稀土企业大量兴起,P507和煤油作为磷酸酯类萃取剂和有机溶剂,是稀土萃取分离工艺制备单一稀土氧化物的主要原材料,也是工业废气的主要来源。若排放到空气中,这些有害气体多数易燃易爆,其大量排放不但对地球环境产生严重的影响,而且还是引起大气光化学烟雾、温室效应和臭氧层破坏的原因之一。同时由于其表现出的刺激性、特殊气味能导致人体呈现出种种不适反应,危害人体健康,尤其是生产一线的工作人员。但目前针对稀土萃取分离工业产生废气的排放特征研究相对较少,数据量有限。 

浩瀚色谱（山东）应用技术开发有限公司参照HJ604—2017和HJ38—2017测定总烃、甲烷和非甲烷总烃。对仪器条件进行优化,对采样容器的影响进行了分析,对校准曲线、精密度、准确度、加标回收率进行了测定,得出总烃精密度为0.4%～1.3%,甲烷精密度为0.3%～1.1%,总烃准确度为-5.5%～1.9%,甲烷准确度为-2.1%～1.9%,总烃加标回收率为94.7%,甲烷加标回收率为92.7%;该实验方法操作简单,分析速度快,结果令人满意。

In recent years, a large number of rare earth enterprises have emerged. P507 and kerosene, as phosphate ester extractants and organic solvents, are the main raw materials for the preparation of single rare earth oxides by the extraction and separation of rare earths, and are also the main sources of industrial waste gas. If discharged into the air, most of these harmful gases are flammable and explosive, and their massive emissions not only have a serious impact on the earth's environment, but are also one of the causes of atmospheric photochemical smog, greenhouse effect and ozone layer destruction. At the same time, due to its irritating and special odor, it can cause various uncomfortable reactions in the human body, which endanger human health, especially the front-line workers. However, there are relatively few studies on the emission characteristics of waste gas produced by the extraction and separation of rare earth industry, and the amount of data is limited.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determines total hydrocarbons, methane and non-methane total hydrocarbons with reference to HJ604-2017 and HJ38-2017. The instrument conditions were optimized, the influence of the sampling container was analyzed, and the calibration curve, precision, accuracy, and recovery rate of standard addition were determined. 0.3% to 1.1%, the accuracy of total hydrocarbons is -5.5% to 1.9%, the accuracy of methane is -2.1% to 1.9%, the recovery rate of total hydrocarbons is 94.7%, and the recovery rate of methane is 92.7%; this experiment The method is simple to operate, fast to analyze, and the results are satisfactory.
