Application

Metals in Sewage Sludge - PT is an inorganic soils/hazardous waste proficiency testing material, suitable for testing the concentration of metals in sewage sludge samples. Our soil PT samples behave as real samples; and, unless there is no alternative, are not simply spikes added to a blank soil. They are designed to meet the requirements of national, regional and state-specific accreditation bodies (TNI, USEPA, UKAS) for quality assurance and continuous improvement.Have any questions?

Preparation Note

Description This natural matrix sludge was collected from a municipal sewage treatment plant and fortified to meet TNI requirements. Due to the nature of sewage sludge some analytes may exceed the TNI range. The PT sample contains 26 TNI metals plus strontium, titanium and silicon reported as Si. The PT sample can be analyzed for ammonia as N, TKN, total phosphorus, TOC and total solids. A total sample size of 100 g is provided. The PT sample has been sterilized and sized to 100 mesh. Recommended storage condition is 4 ºC. The evaluation of results will be based on study statistics for equivalent methods. Determine the metals present, the concentration, and report your results on the analysis data sheet provided. If multiple methods are used for preparation and/or analysis, a separate report form must be used for each preparation and analysis method.Sample Preparation Perform the sample digestion on an appropriate amount of sample according to the selected digestion procedure. Determination of the percent moisture content of the material is required. Report all results on a dry weight basis. It is recommended that approximately one gram of the soil be digested for metals analysis. Determine the metals present, the concentration, and report your results in the PT portal.
