A simple EDXRF technique to analyse alloys

The European Physical Journal Applied Physics, 2002
A simple EDXRF technique to obtain the relative concentrations of different elements present in a sample is described here. Only those elements have been considered whose characteristic X-rays fall within the sensitivity range of the X-ray detector that we used.

Multielemental evaluation of garbage bags by EDXRF

International Journal of Environmental Analytical Chemistry, 2014
Garbage bags have been broadly used for collecting household waste in Brazil and worldwide. Many of these bags are made from recycled polymers, and the presence of harmful elements is a matter of concern. In this study, an energy dispersive X-ray fluorescence (EDXRF) approach for direct analysis of garbage bags is proposed. The concentrations of K, Ca,
