噻吩是无色液体,是最简单的含硫五节杂环化合物,毒性作用主要是影响人体中枢神经系统,对造血系统亦有毒害作用,动物中毒表现与苯中毒相似。噻吩在我厂硫磺回收环烷酸装置区被首次检出。由于它的存在,严重干扰(AgNO)_3法测定H_2S。目前我国尚无噻吩卫生标准及监测方法。我们参考有关文献建立了用活性炭管富集空气样品热解吸脱附气相色谱法测定噻吩的方法。 1 仪器与方法 Thiophene is a colorless liquid. It is the simplest sulfur-containing five-membered heterocyclic compound. The toxic effect is mainly on the central nervous system of the human body and also on the hematopoietic system. The poisoning of animals is similar to benzene poisoning. Thiophene was first detected in the sulfur recovery naphthenic acid plant zone in our plant. Because of its existence, serious interference (AgNO) _3 method for the determination of H_2S. At present, there is no thiophene health standards and monitoring methods in our country. With reference to the literature, we established a method for the determination of thiophene by pyrolysis desorption and gas chromatography with activated carbon tube enrichment air sample. 1 instruments and methods
