| Abstract: | Atomic absorption spectroscopy procedures are outlined for the determination of some important heavy metals in sewage treatment plant solids and liquids. Problems associated with sample preparation and sample solution interferences are described. It is recommended that reference standards and internal laboratory control samples be used to allow some assessment of the validity of results. Sewage treatment plant products both liquid and solid were analyzed and results given for samples representing a wide range of sewage input patterns. |
