“…5 ml of HNO 3 added to 1 L of water to prevent the loss and adhesion of the trace elements on container glass walls. The pre-concentration procedure 3,8 was applied to water samples by evaporation at 50 • C under atmospheric pressure to obtain dry dissolved solid residue. Total solid concentration is the weight of the residue left after water is evaporated to dryness (mg/L), and includes dissolved and particulate matter (with the exception of gases).…”

Analysis of trace and toxic metals in untreated rainwater has been carried out using nondestructive proton induced X-ray emission (PIXE) in combination with preconcentration technique. The pre-concentration technique used for this purpose was carried out by evaporation of the rainwater samples at 50 • C under atmospheric pressure. Untreated rainwater samples were collected from 10 different locations across Baghdad city, Iraq. The mean concentration values of the elements (Al, Ca, Co, Ti, V, Cr, Mn, Fe, Zn, Br, Rb and Sr) in rainwater samples were determined simultaneously at the parts per billion (ppb) levels. The rainwater samples and certified reference materials (CRMs) were irradiated with 2.0 MeV proton beam from Van de Graaff accelerator. The accuracy of the results was proved by using certified reference materials (GSP-2). The results were compared with the published data, Iraqi standards (IRQ), European standards (EU), and World Health Organization (WHO) guidelines for drinking water quality. The purpose of this work was to obtain the total elemental compositions of rainwater in Iraq.

“…Monitoring the concentration of Fe 3+ in drinking water is crucial for the preservation of public health. Water purification facilities commonly employ spectroscopy techniques, such as atomic absorption spectroscopy (AAS) 13 , inductively coupled plasma-mass spectrometry (ICP-MS) 14 , cold-vapor atomic fluorescence spectroscopy (CV-AFS) 15 , and neutron activation analysis (NAA) 16 , to quantitatively monitor iron levels in water. However, these techniques are expensive, destructive, and highly labor-intensive [17][18] .…”

A new coumarin-based fluorescent chemosensor, 3, incorporating a hydrazone (-NH-N=C-), was designed and synthesized. The chemosensor displayed higher affinity towards Fe 3+ in water-acetonitrile solution in the presence of other competing cations in emission and absorption essays. The binding stoichiometry between the chemosensor 3 and Fe 3+ was shown to occur in a 1:1 ratio, and the binding modes of the chemosensor towards Fe 3+ were identified through the emission response, 1 H NMR, FT-IR and molecular modelling studies. The hydroxyl and amine functionalities on 3 were recognized as possible binding sites. The chemosensor presented a limit of detection, a limit of quantification and the association constant of 0.45 µM, 1.50 µM and 3.01 × 10 1 M -1 , respectively.
