摘要:
收集了上海地区在1987年7月至1988年5月间66个雨水样品,现场监测了雨水中的过氧化氢,并分析了其中H+,Na+,K+,NH4+,Ca2+,Mg2+,F-,Cl-,NO-3和SO42-的浓度。结果表明,雨水中过氧化氢含量最高可达3390ppb;〔H2O2〕与〔H+〕及降雨量有较明显的相关性;在闪电及雷阵雨时,雨水中的过氧化氢含量往往较高。因而,雨水中〔H2O2〕对〔H+〕有重要贡献。
Abstract:
The concentrations of hydrogen peroxide, H+, K+, NH4+ Ca2+, Mg2+, F+, Cl-, NO3- and SO42- in 66 samples of rain water were determined in Shanghai area from July 1987 to May 1988. High level of H2O2 in rain water was observed, the maximum H2O2 was as high as 3390 ppb. The concentration of H2O2 was obviously related to [H+] and rainfall. Under storm and lightening, the concentration of H2O2 would increase,Therefore [H2O2] contributed much to [H+] in rainwater
