Thirty-nine paired soil samples belonging to Inceptisols, irrigated with wastewater and well water, were examined to monitor the combination of clay mineralogy, physicochemical properties, and trace metals (Zn, Cu, Cd, and Pb) following long-term wastewater irrigation. Results of XRD analysis indicated that the quantity of clay minerals did not change by(More)
In order to study the behaviour of trace impurities during aqueous dissolution of a sample, aluminium and nickel-based alloys containing 10(-4)-1% Ir, Os or Ru were used. Yields of chemical separations such as distillation and ion-exchange were chosen as dissolution criteria. Dissolution of aluminium samples leads to precipitation of the three impurities.(More)
A simple and rapid method for the quantification of lamotrigine (LTG) was developed using 4-aminothiophenol-stabilized gold quantum dots (4-ATP-AuQDs) and amidosulfonic acid-capped silver nanoparticles (ASA-AgNPs) as a new fluorescence resonance energy transfer (FRET) probe. 4-ATP-AuQDs and ASA-AgNPs were synthesized and characterized by UV-Vis and(More)
