| 摘 要： | 对河南省分布的主要土类耕层土壤100个土样抽样调查,分析测定了土壤类型、质地、有机质含量、pH值,并采用王水-高氯酸消解、电感耦合等离子体发射光谱仪对土壤样品中的镍含量进行了测定.结果表明:土壤镍含量有差异,镍含量平均值大小为砂姜黑土＞褐土＞红粘土＞潮土＞黄褐土＞黄棕壤土,其含量平均分别为18.47mg/kg、17.1mg/kg、16.22mg/kg、15.60mg/kg、15.06mg/kg和9.88mg/kg,均低于国家<土壤环境质量标准>(GB 15618-1995)中规定的镍含量(≤40mg/kg)标准.

| Abstract: | A sample investigation was carried out with 100 main topsoil samples in Henan.The soil types,texture,organic contents and pH of the samples were determined.The Ni content was detected by digestion with aqua regia-perchloric acid and using(ICP-OES).The results show that the Ni content varies among the soil types,with the order of mean content as shajiang black soils > cinnamon soils > red clay > fluvo-aquic soils > yellow cinnamon soils > yellow palmloamy soils.The average Ni content is 18.47 mg/kg,17.1 mg/k... |
