摘 要:本文采用混合酸(HNO3:HClO4=4:1)对潮州市区公路(东山路,清洁区)两侧的土壤进行处理,利用萃取分光光度法对土壤中的铅进行了测定,并分析了土壤铅污染程度和分布规律.结果表明:潮州市郊区公路两侧土壤中铅的含量比清洁区高1.25~1.90倍,并随距离增大,土壤铅含量逐渐降低.In this paper the mixed acid ( HNO3: HClO4 = 4:1 ) was used to dispose of the soil plumbum sample from both sides of the highway in Chaozhou urban district (Dongshan Road,Cleaning District ), Using Extraction Luminostiy method to determine the plumbum in the soll ,and analyzing the degree of contamination and the regularing of distribution,the outcome indicates that the plumbous content is higher than that of the cleanness district in the soil of both sides of suburb highway of Chaozhou, it is its 1.25 - 1.90 times, and as the distance increases, the plumbum content of soll is reduced gradually.
