摘　　要：介绍化学品生物降解性能评价的主要标准和方法,结合泡沫灭火剂的理化特点分析了这些方法应用于泡沫灭火剂生物降解性能评估的可行性。参照GB/T 21856-2008(等同采用OECD 301B)试验方法,研究并建立了基于CO2产生法的泡沫灭火剂生物降解性评估方法,并用以测定泡沫灭火剂常用组分十二烷基硫酸钠和国产A类泡沫的生物降解性能,证明了所建立的实验方法及实验装置的有效性,指出采用CO2产生法测定泡沫灭火剂的生物降解性能是可行和可靠的。The available test methods and standards for biodegradation test of chemicals were briefly reviewed;also the application of these methods in the firefighting foams biodegradation test was discussed combined with physical and chemical characteristics of firefighting foams.An evaluation system based on CO 2 evolution method referenced to test methods of GB / T 21856-2008(equivalent OECD 301B) was established to evaluate the biodegradation of sodium dodecyl sulfate and Class A foam.The results indicated that it is reliable and feasible to evaluate the biodegradation of firefighting foams using CO2evolution method.
