Abstract

The constant projected increase in electronic-waste (e-waste) generation coupled with the high costs of several raw materials employed by the electronics industry are factors that justify studies regarding new analytical methodologies suitable for applications in recycling centers, industrial facilities and academic laboratories. Longer preparation routines for sample analysis and the diverse physical and chemical characteristics of these materials are challenges frequently encountered during the development of analytical procedures. In this work, laser-induced breakdown spectroscopy (LIBS) was applied to the direct investigation of Au and Ag in computer scraps and in the electromagnetic shielding of mobile phone housings. The results show that this technique can be a useful tool for obtaining information regarding the profiles of these elements at the surface and in the bulk of these materials without preparation steps and for semi-quantitatively evaluating Ag in the type of samples analyzed.
