This study is aimed to establish a simple, rapid, and accurate ion chromatography approach for the simultaneous detection of six inorganic anions in urine. Various performance parameters affecting the determination of anions were optimized, including the selection of sample protein precipitation agent, eluent, and flow rate. The final eluent was 3.6 mmol/L sodium carbonate and 12% isopropanol with a flow rate of 0.6 mL/min. Acetonitrile was used for pretreatment to precipitate proteins, and the volume ratio of urine to acetonitrile was 1:4. The correlation coefficient of the target anion calibration curve ranged from 0.9973 to 0.9999.The limit of detection ranged from 1.50 to 12.0 μg/L, and the method detection limit ranged from 15.0 to 120 μg/L. The standard recovery rate for low, medium, and high concentrations ranged from 90 to 110%. The inter-day and intra-day relative standard deviations were <5%. The method has high accuracy and good reproducibility and is suitable for the separation and determination of anions in urine.

“…NH 4 + ions were determined spectrophotometrically at λ = 420 nm (Thermo Scientific Evolution 600) using Nessler’s reagent (0.09 mol/L solution of potassium tetraiodomercurate (II) (K 2 [HgI 4 ]) in 2.5 mol/L potassium hydroxide). The ion chromatograph operation method is explained in Michalski [37].…”

Several epidemiological studies have shown a close relationship between the mass of particulate matter (PM) and its effects on human health. This study reports the identification of inorganic and organic components by attenuated total reflectance-Fourier-transform infrared spectroscopy (ATR-FTIR) analysis in PM10 and PM2.5 filters collected from three air quality monitoring stations in the city of Palermo (Sicily, Italy) during non-Saharan dust events and Saharan events. It also provides information on the abundance and types of water-soluble species. ATR-FTIR analysis identified sulfate, ammonium, nitrate, and carbonate matter characterized by vibrational frequencies at 603, 615, 670, and 1100 cm–1 (SO42–); at 1414 cm–1 (NH4+); at 825 and 1356 cm–1 (NO3–); and at 713, 730, and 877 cm–1 (CO32–) in PM10 and PM2.5 filters. Moreover, aliphatic hydrocarbons were identified in the collected spectra. Stretching frequencies at 2950 cm–1 were assigned to CH3 aliphatic carbon stretching absorptions, while frequencies at 2924 and 2850 cm–1 indicated CH2 bonds. In filters collected during Saharan dust events, the analysis also showed the presence of absorbance peaks typical of clay minerals. The measurement of soluble components confirmed the presence of a geogenic component (marine spray and local rocks) and secondary particles ((NH4)2SO4, NH4NO3) in the PM filters. ATR-FTIR characterization of solid surfaces is a powerful analytical technique for identifying inorganic and organic compounds in samples of particulate matter.

“…This is dictated by a greater need for monitoring industrial wastes, e.g., wastewater from pulp or paper mills, or residual pesticides and herbicide levels in food chains. IC-MS has been widely used in environmental sciences since the 1980s in various forms, and its applications have recently been reviewed elsewhere. , Here, we focus on a brief history and some of the more recent studies using online electrolytic ion-suppression. Since the mid-1980s, IC was established as the only method for analysis of inorganic anions in environmental samples, and therefore, the development of IC-MS brought new analytical capabilities to already established protocols.…”

“…Since the mid-1980s, IC was established as the only method for analysis of inorganic anions in environmental samples, and therefore, the development of IC-MS brought new analytical capabilities to already established protocols. Applications included analysis of oxyhalides, ,− Cr (VI), nitrogen- or sulfur-based ions, and metal–EDTA complexes (Table ). While analysis of inorganic chemicals using IC-MS has long been established, analysis of organic molecules in environmental samples has largely been carried out using GC-MS, IP-MS, or HILIC-MS methods .…”
