Method and device for determining chemical element contents and bond forms in a material

摘要

A method for determining chemical element contents and bond forms in a material (2), comprising a) conveying the material (2), b) taking a sample (5) of the material (2) conveyed in accordance with step a), c) analyzing the in step b ) taken sample (5) by means of ETV-ICP-OES and / or by means of ETV-ICP-MS in order to determine the chemical element contents and bond forms in the material (2) with the described method and the corresponding device (1) for determination of chemical element contents and binding forms in a material (2), the chemical element contents and binding forms in a conveyed material (2) can be determined directly online without laborious laboratory analysis. In the described method and the corresponding arrangement (10) for evaluating and treating sewage sludge, knowledge of the chemical element content of phosphorus and its bond forms can be used to efficiently recover phosphorus from the sewage sludge.
