| 摘 要： | 采用HNO3—HClO4—HF湿法消解样品,用电感耦合等离子体发射光谱法(ICP—AES)测定底泥中重金属(Al,Cu,Co,Mn,Zn,Fe,Pb,Cd,Ni)及磷的质量分数,用水系沉积物标准样品进行对照,其测定值与标准值吻合得很好,方法的相对标准偏差sr在6％以内,结果令人满意。采用本法对官厅水库坝址到妫水河的重金属及磷的质量分数进行了测定与分析,为官厅水库底泥处置和底泥污染治理提供了技术依据和指导性分析。

| Abstract: | The concentration of ten elements(Al,Cu,Co,Mn,Zn,Fe,Pb,Cd,Ni,P) of the sediment in Guanting Reservoir is determined by ICP AES.For the multielement analysis of sediments. A useful procedure is the following: a dissolution with a hydrofluoric hypochloric nitric acid mixture,subsequent vaporation of the acids and dissolution of the residue by HNO 3. Satisfactory results for standard reference material are obtained.In accordance with this method,heavy metals and phosphorus of the sediments in Guanting Reservoir are determined.It is predicted that the testing method is accurate and reliable. |
