“…Mean dissolved lignin export was lower in BB (9.65 ± 6.38 × 10 4 kg/year) than in AP (3.48 ± 2.20 × 10 5 kg/year), and mean particulate lignin export was higher in BB (4.76 ± 2.97 × 10 5 kg/year) than in AP (7.34 ± 3.15 × 10 4 kg/year; Table ). The reported dissolved lignin fluxes in this study are likely underestimates due to inefficiencies of Solid‐Phase Extraction‐Priority PolLutant (SPE‐PPL) (41% LOP recovery rates; Arellano et al, ). It was clear the largest fraction of export was particulate lignin from BB, and indeed this fraction was larger even than the export of dissolved lignin from AP.…”

“…DOM was extracted on hydrophilic-lipophilic balanced (HLB) cartridges according to the method of Keil and Neibauer (2009) and Arellano et al (2018). CuO oxidation products were extracted and analyzed according to Hedges and Ertel (1982), as modified by Goñi and Hedges (1995) and further modified by Louchouarn et al (2010).…”

Modifications in land use and climate will result in shifts in the magnitude and composition of organic matter (OM) transported from wetlands to coastal waters, but differentiation between riverine and wetland OM sources in coastal areas remains a challenge. Here, we evaluate particulate and dissolved OM export dynamics in two representative estuary geomorphologies—Apalachicola Bay (AP) and Barataria Bay (BB), characterized primarily by blackwater river inputs and high particle abundance, respectively. The magnitude and composition of OM exported from each estuary was evaluated based on seasonal measurements of surface water dissolved organic carbon (DOC), particulate organic carbon (POC), particulate nitrogen, the stable isotopic composition of DOC and POC, dissolved and particulate lignin phenols, and carbon‐normalized dissolved lignin‐phenol yields. Data and discriminant analyses support the initial hypothesis; AP is dominated by a more terrestrial source of OM due to importance of fluvial dissolved OM inputs, while BB is a more particle‐rich and wetland carbon‐dominated system. Total lignin export (sum of mean dissolved and mean particulate) was higher in BB (5.73 ± 2.50 × 105 kg/year) than in AP (4.21 ± 2.35 × 105 kg/year). Particulate lignin export from BB was greater than the export of dissolved lignin at either BB or AP, suggesting coastal marsh erosion may be driving this comparatively large export of particulate lignin. These data have important implications for the stability of stored OM in coastal habitats, particularly since such habitats in this region are highly vulnerable due to relative sea level rise.

“…Hence, the extraction of DON molecules must be taken into account. However, Arellano et al (2017) indicated a low extraction efficiency for DON in coastal samples using the PPL sorbent. On the other side, Spanik et al (2007) showed that strong cation exchange resin can be used for the pre-concentration of amino acids in water samples.…”

Comparison of different solid phase extraction sorbents for the qualitative assessment of dissolved organic nitrogen in freshwater samples using FT-ICR-MS

2018

Fate and reactivity of dissolved organic matter (DOM) is directly linked to its chemical composition. Therefore, molecular characterisation, for example using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), is used for a better understanding of those factors. To study organic compounds in the water column, an efficient extraction method is important. The commonly used extraction method for FT-ICR-MS is solid phase extraction (SPE) using a reversed-phase sorbent (BondElut PPL). But this method, to the best of our knowledge, was not evaluated for its ability to extract organic nitrogen compounds which are important building blocks of life and therefore an important fraction of DOM. In this study, several solid phase sorbents were tested for their ability to extract organic nitrogen compounds from water samples of natural aqueous environments. Different cartridges concerning their retention mechanism and pore size were tested. Three cartridges with different extraction mechanism (reversed phase, cation exchange or a mixture of both) or different pore size were tested. Except for one sorbent type, which heavily contaminated the samples with organic molecules, the tested cartridges leached neither a significant amount of dissolved organic carbon (DOC) nor dissolved organic nitrogen (DON). The sorbents were tested with lake water to be able to investigate their functionality in real conditions. It could be shown, that the molecular composition of the sample should be considered for the choice of the sorbent material. Additionally, it was shown that a mixed-bed sorbent is a valuable complementary SPE sorbent for the molecular characterisation of lacustrine samples using FT-ICR-MS and it might also be useful for a quantitative extraction. Furthermore, it could be shown that HyperSep Retain CX sorbent allows to extract a broader range of organic nitrogen compounds leading to a more comprehensive data set for investigating organic nitrogen compounds in lakes using FT-ICR-MS.

“…In this case a change in molecular composition of the DOM isolate, which was brought about by a purely methodical bias (molecular selectivity of the new sorbent) can lead to erroneous conclusions and interpretations with regard to the course of environmental processes. The existence of molecular selectivity is numerously reported [17,18]. Our previous studies have shown [18] that a use of Bond ELut PPL cartridges versus Amberlite XAD-8 resin gave very different samples of DOM from the same water: the former were enriched with aliphatic components, whereas the latter were rich in aromatic structures.…”

“…Application of Bond Elut PPL cartridges for isolation of the Suwannee River DOM gave DOC recovery results of 89% [16]. Comparison of three types of sorbents (C-18, PPL, and HLB) was reported for DOM and lignin-phenols [17]. It showed that DOC recovery was the best for PPL (60% for rivers and 47% for coastal DOM).…”

Large scale isolation—in gram quantities—of dissolved organic matter (DOM) from natural waters is necessary for detailed investigation of its role in chemical and microbial processes driving carbon cycling under conditions of global climate change. The best candidate for a use in these large-scale experiments is a bulk sorbent Bondesil PPL, which has the same modification as the widely used Bond Elut PPL sorbent. There have been no studies so far reported on interchangeability of these sorbents with regard to DOM isolation. This work was devoted to comparative studies on sorption efficiency and molecular selectivity of these two sorbents—Bond Elut PPL and Bondesil PPL with regard to DOM components. Fulvic acids (FA) from peat water leachate were used as a model DOM. Laboratory solid phase extraction (SPE) setup was used for monitoring sorption recovery and extraction yield. It included three parallel experiments on pre-packed Bond Elut PPL cartridges (500 mg/3 mL) and three self-packed Bondesil PPL cartridges (500 mg/3 mL). Fourier transform ion cyclotron resonance mass spectrometry (FT ICR MS) and 13C/1H nuclear magnetic resonance (NMR) spectroscopy were used for determination of molecular and structural group compositions of the FA isolates obtained with a use of two different sorbents. The results of this study allowed a conclusion on interchangeability of the two sorbents used in this study for the purposes of DOM isolation from natural waters. This conclusion was backed up by similarity of sorption behavior of the peat FA components on both sorbents and by high similarity of molecular compositions and carbon distribution among the main structural groups.
