摘　　要：研究了添加光敏剂二丁基二硫代氨基甲酸铁(FeDBC)、乙酰丙酮铁(FeAcAc)、苯并蒽酮(BAN)的光氧化农用地膜的降解行为。结果表明,在双组分光敏剂的协同作用下,农用地膜的光氧化降解程度显著增加。The photo - oxidized degradation behavior of the LDPE agricultural film containing photosensitizer such as FeDBC {[(CH3CH2 · CH2CH2)2NCSS]3Fe}, FeAcAc (Ferric acetylacetonate) and BAN (benzanthrone) were studied in this paper. The experimental results showed that the photodegradation property of the agricultural film was obviously improved under the synergism of the two kinds of photosensitizers i.e. FeDBC + BAN or FeAcAc + BAN.
