Nucleotides, as the basic building blocks of nucleic acids, widely exist in aqueous environment. In this study, we developed a solid phase extraction-high performance liquid chromatog.-tandem mass spectrometry (SPE-UPLC-MS/MS) method for the anal. of 5′-adenosine monophosphate (AMP), 5′-uridine monophosphate (UMP), 5′-cytidine monophosphate (CMP) and 5′-guanosine monophosphate (GMP). The method achieved limits of detection (LODs) of 0.1-1.0 ng/L, and recoveries of 85-95% for the four tested nucleotides. The occurrence and concentrations of the four nucleotides in water from eight representative drinking water treatment and distribution systems in China were determined using this method. All four nucleotides were detectable in water treatment plant (WTP) influent and effluent, at concentrations of up to 30 ng/L and with occurrence frequency of around 90%. The concentrations of identified nucleotides increased 3-10 times after 10 km of water age in the water distribution system. Biol. filters and coagulation increased the concentrations of nucleotides, conversely, active carbon, ozonation, and ultrafiltration membrane removed nucleotides in water. The effects of active carbon and coagulation were further confirmed using laboratory-controlled experiment In addition, monochlorinated nucleotides were identified as the chlorination products of nucleotides.
Science of the Total Environment published new progress about Coagulation. 58-97-9 belongs to class tetrahydrofurans, and the molecular formula is C9H13N2O9P, Recommanded Product: ((2R,3S,4R,5R)-5-(2,4-Dioxo-3,4-dihydropyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl dihydrogen phosphate.
