采用吹气浓缩法和气相色谱分析法,可以测定水中含量为0.004毫克/升的氯丁二烯、二乙烯基乙炔和苯,并测定含量为0.006毫克/升的乙醛。应用此法已为氯丁橡胶生产废水的深度处理试验检验了处理效果,初步探索了活化煤的动态吸附过程,此法也适用于测定水中十亿分之一(微克/升)级或浓度更低的其他挥发性有机物。 Using air-blowing concentration and gas chromatography, chloroprene, divinyl acetylene and benzene with a water content of 0.004 mg / L can be determined and acetaldehyde content 0.006 mg / L can be determined. This method has been tested for the treatment of neoprene production wastewater treatment effect, initially explored the kinetic adsorption of activated coal adsorption process, this method is also applicable to the determination of water one billionth (microgram / liter) level or concentration more Low other volatile organic compounds.
