摘要
研究了单组份光敏剂ＦｅＤＢＣ、ＦｅＡｃＡｃ、ＢＡＮ和双组份光敏剂ＦｅＤＢＣ＋ＢＡＮ、ＦｅＡｃＡｃ＋ＢＡＮ在地膜光降解中的行为．结果表明：一定含量的双组份光敏剂的光降解行为与其单组份光敏剂的光降解行为相似，一定含量的双组份光敏剂的光降解具有加和或协同作用．
The photodegradable behavior of one/twin photosensitizer FeDBC,FeAcAc,BAN and FeDBC+BAN,FeAcAc+BAN in photodegradation of LDPE film is studied.The experimental results show that photodegradable behavior of twin photosensitizers with some concentration is close to that of one photosensitizer with the same concentration, and photodegradable behavior of twin photosensitizers with certain concentration shows repeated addition/synersism effect.
