Description
|
The sample consists of about 50 g of homogeneous, powdered calcareous loam soil in brown glass bottles provided with a polyethylene insert and a screw cap. Additional information on the major composition, the preparation, the analytical methods and the certified values is given in the certification report. The sample can be used as it is from the bottle. Before a bottle is opened, it should be shaken manually so that the material is re-homogenised. The correction to dry mass should be made on a separate portion of 1 g which should be dried in an oven at 102 ºC for 3-4 h until constant mass is attained. The recommended minimum sample intake (for total element determinations) is 50 mg. Treatment with HF is recommended for the determination of total contents. The digestion procedure used for the determination of the aqua regia soluble contents (DIN 38414-S7) is described in detail in the certification report. Storage of the material in a dessiccator is recommended; prolonged exposure to sunlight should be avoided. keywords: environmental material , Soil/Sediment , trace elements , heavy metals, fractionation analysis , aqua regia soluble fraction |
