In a physicochemical context, experiments were carried out to study the pseudo-first-order oxidation rate constant (k\u2032, min\u20131) over a range of pH (7.8, 7.9, 8.0, and 8.1) and temperature (10, 15, 20, and 25 \u00b0C). Deviations from the calculated kcal\u2032 at the same T, pH, and S were observed for most of the stations. The measured t1\/2 (ln 2\/k\u2032, min) values at the 25 stations ranged from 1.82 to 3.47 min (mean 1.93 \u00b1 0.76 min) and for all but two stations were lower than the calculated t1\/2 of 3.21 \u00b1 0.2 min. In a biogeochemical context, nutrients and variables associated with the organic matter spectral properties (CDOM and FDOM) were analyzed to explain the observed deviations. The application of a multilinear regression model indicated that k\u2032 can be described (R = 0.921 and SEE = 0.064 for pH = 8 and T = 25 \u00b0C) from a linear combination of three organic variables, k\u2032OM = kcal\u2032 \u22120.11* TDN + 29.9*bDOM + 33.4*C1humic, where TDN is the total dissolved nitrogen, bDOM is the spectral peak obtained from colored dissolved organic matter (DOM) analysis when protein-like or tyrosine-like components are present, and C1humic is the component associated with humic-like compounds obtained from the parallel factor analysis of the fluorescent DOM. Results show that compounds with N in their structures mainly explain the observed k\u2032 increase for most of the samples, although other components could also play a relevant role. Experimentally, k\u2032 provides the net result between the compounds that accelerate the process and those that slow it down.<\/jats:p>","DOI":"10.1021\/acs.est.1c04512","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T13:54:02Z","timestamp":1643118842000},"page":"2718-2728","source":"Crossref","is-referenced-by-count":20,"title":["Exploring\nthe Effects of Organic Matter Characteristics\non Fe(II) Oxidation Kinetics in Coastal Seawater"],"prefix":"10.1021","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7930-7683","authenticated-orcid":true,"given":"J.
