Ferrous metals are more often usefully analyzed using optical microscopy. Establishing compositional groups requires a more detailed analysis of minor and trace elements using the more advanced methods of chemical analysis and the need to compare data from different laboratories. When reconstructing ...

Metal recycling plays a crucial role in mitigating the shortage of critical metals and reducing reliance on primary mining. Current liquid hydrometallurgy involves substantial water and chemical consumption with troublesome secondary waste streams, while
The source of the atmospheric particles was analyzed based on the enrichment factor method, and the carcinogenicity of the atmospheric particles was analyzed using the health risk model. The partition contents of metals extractable by a weak acid, including As, Ca, Cd, Cs, Pb, Sr, and Zn, ...
BCR three-step procedure, proposed by Standards, Measurements and Testing (SM&T) Programme of European Commission, has been demonstrated to be a successful method for determining the speciation of heavy metals, which reaches a compromise between analysis time and the amount of information obtained. ...
