Quantification of metals in river water using a portable EDXRFsystem

This work identified, quantified, and presents results for metals in water using a portable energy dispersive X-ray fluorescence (EDXRF) system. It was possible to quantify the following range of concentrations in mg L−1: Ca(0.043-0.021), Ti(0.137-0.014), Mn(0.052-0.008), Fe(1.66-0.035), Ni(0.012-0.010), Cu(0.010-0.007), Zn(0.070-0.007), and Pb(1.01-0.85). The final conclusion is that in 4 h of field work it was possible to prepare, measure, and analyze 14 membranes.
