摘要
研究了腐殖质对水体中六六六降解过程的促进作用。将α、β、γ和δ六六六分别配成20、30、50ng/ml的水溶液标样,加入浓度为5mg/ml腐殖质溶液,用气相色谱测定降解后浓度。实验室降解效率大于97·6%。并初步探讨了降解原理,主要是水体中腐殖质光敏反应产生的氧自由基和·OH,氧化分解了六六六,降解产物主要是辛醇、庚醇、酚类。
The analysis indicated that HCHs can be degraded by humic substance in the water. Adding 5 mg/ml humic substance into 20,30,50 ng/ml HCHs（α,β ,γ and δ）, HCHs isomers were analyzed on GC. About 97% HCHs are degraded. Then there are 102 and · OH in the water,which were generated by photochemical reaction of humic substance, which degrades the HCHs. Degradation products are octanol, heptanol, and phenol.
