Data for: A dataset of 112 ligands for the preconcentration of mercury, uranium, lanthanum and other pollutants and heavy metals in water

The energy dispersive X-ray fluorescence (EDXRF) spectra for mercury (Hg) preconcentration in water along with the EDXRF spectra for 112 ligands, immobilized on anion-selective membranes, screened for calcium (Ca), iron (Fe), nickel (Ni), zinc (Zn), strontium (Sr), lanthanum (La), uranium (U), copper (Cu), and gold (Au) preconcentration in tap water.
