ABSTRACT With the increasing environmental pollution issues, there is a growing need for sensitive and real‐time monitoring of pollutants. Nitrite nitrate are common nutrients that related to water quality. This study aims enhance nitrite detection capabilities using portable ion chromatography‐based nutrient analyzer, Aquamonitrix. By optimizing it ultra‐low limits (LODs), we address challenges in quality assessment Tasmania, Australia. Using step‐gradient mode with stereolithography three‐dimensional printed flow cell 5 cm optical path length, 300 µL injection loop, 60 mM KOH as eluent, LODs 0.004 µg/mL 0.023 were achieved. Further improving 0.008 10 length 120 NaCl eluent. A repeatability over 84 automatic runs showed relative standard deviation under 1.42% peak area 0.49% retention time. The system demonstrated tolerance salinity, handling up parts per thousand artificial seawater. Comparative analysis samples revealed levels Tasmanian rainwater five times lower than Ireland. An average concentration 2.08 was found Tamar River samples, aligning local commercial lab data. Real‐time, on‐site along Derwent detected an 0.17 µg/mL. Validation against conventional chromatography no significant differences ( p > 0.05), underscoring Aquamonitrix's robustness field‐based monitoring. 5‐day deployment Aquamonitrix further system's reliability temperature fluctuations between day night.

The monitoring of nitrate ions is great significance for human health, agricultural development, and environmental protection. All-solid-state ion-selective electrodes (ASS-NO3--ISEs), as an important NO3- analysis method, still have two challenges poor stability reproducibility due to the ill-defined phase boundary between solid-contact (SC) layer membrane (ISM). In this work, a novel strategy constructing ASS-NO3--ISEs based on CoWO4, CoWS4, CoWSe2, or CoSe2 SC layers was reported improving reproducibility. result shows that developed CoWSe2-based NO3--ISE exhibits good Nernstian response slope -61.9 ± 0.4 mV dec-1 in activity range from 1.0 × 10-6 7.5 10-2 M detection limit M. A long-term (as low 2.3 μV h-1) primary reason high redox capacitance ternary selenide. Experimental results show surprisingly approximately 0.5 five individual ASS-NO3--ISEs. Notably, electrochemical experiments scanning electron microscopy mapping tests are used predict ion-electron transduction mechanism which lipophilic anion (tetrakis(4-chlorophenyl)borate) participates process at SC/ISM interface stabilize electrode potential provide It further proved introduction CoWSe2 maintains excellent anti-interference water layers, light, gas. Hence, achieve accurate free wetland soil estuary Yellow River delta.

Miniaturized LC, encompassing capillary and nanoLC, presents significant analytical advantages in enhanced chromatographic performance detectability delivers considerable environmental economic benefits. Despite these advantages, its utilization has primarily remained confined to omics sciences, with limited adoption the routine targeted analysis of small molecules despite lack practical limitations. Initially, miniaturized LC encountered challenges related scale reduction, necessitating handling minute sample volumes lower flow rates. However, obstacles have largely been overcome, various instrumental platforms, columns, consumables now available for efficient separations at scale. Moreover, miniaturization instruments facilitated by nanoLC given rise portable platforms in-situ recent years. Currently, researchers are exploring their applicability diverse purposes. transition from conventional HPLC slow, technical factors limiting this shift still need be clarified. Limited access technology is among primary identified, as transitioning may entail replacing versions. Additionally, a proper training background handle rates hindered widespread nano-LC.
