摘要 用ICP-MS法检测北京市区公路旁尘土中铂、铑和钯各种形态的含量及总含量.结果表明,北京市区采样点公路旁土壤中铂,铑和钯的总量分别为154·23ng·g-1,62·77ng·g-1和77·97ng·g-1,其中非残留态的百分比含量为铑(37·82%)>钯(27·45%)>铂(26·87%);在自然条件作用下可进入地下水和可被植物吸收部分的百分比为铑(29·14%)>钯(23·87%)>>铂(7·92%). With modified sequential extraction and separation analysis method, platinum group elements (PGEs)in roadside dust were divided into five fractions: water soluble, weak acid soluble, exchangeable, acid soluble and 154. 23ng·g^-1, 62. 77ng·g^-1 and 77.97ng·g^-1, respectively. It's shown that the non-residual fractions of Pt, Rh and Pd in urban dust in the order: Rh (37.82%) 〉Pd (27.45%) 〉Pt (26.87%); and the sum of exchangeable and carbonate fractions presented the amounts of bio-available fraction in urban roadside dust in the order: Rh (29. 14%) 〉Pd (23.87%) 〉Pt (7.92%).
