摘要

水生腐殖质(AHS)被定义为有机物的重要组成部分,由超分子结构的小分子组成,可与金属离子相互作用,从而改变这些物种的生物利用率。为了更好地了解这种行为,我们从马瑙斯市附近的内格罗河和伊塔科蒂亚拉市的卡鲁河中提取了 AHS 并对其进行了表征。通过 13C 核磁共振和热水解气相色谱-质谱法对 AHS 进行了表征,以获得其结构特征。采用平行因子分析(PARAFAC)荧光光谱法和傅立叶变换红外光谱法(2D-COS FTIR)二维相关光谱法研究了与铜(II)、铝(III)和铁(III)的相互作用。研究结果表明,旱季的 AHS 含有更多的非木质素芳香馏分,其烷基摩尔质含量较高,这些烷基摩尔质来自微生物来源和原生植物组织;而雨季分离的 AHS 在其分子结构、木质素单元和聚沙酰胺结构中显示出更多的金属元素。研究表明,雨季的 AHS 成分能与 Al (III)、Fe (III) 和 Cu (II) 相互作用。已确定两种荧光成分对相互作用起作用:C1(蓝移)和 C2(红移)。与 C2(KML 范围为 3.1 至 10.0 × 105)相比,C1 显示出更高的络合能力,但络合稳定性常数较低(KML 范围为 0.3 至 7.9 × 105)。二维-COS 傅立叶变换红外光谱显示,酚醛中的 COO- 和 C-O 是与所研究的金属离子相互作用的最重要官能团。

Seasonal studies of aquatic humic substances from Amazon rivers: characterization and interaction with Cu (II), Fe (II), and Al (III) using EEM-PARAFAC and 2D FTIR correlation analyses.

Seasonal studies of aquatic humic substances from Amazon rivers: characterization and interaction with Cu (II), Fe (II), and Al (III) using EEM-PARAFAC and 2D FTIR correlation analyses.

Aquatic humic substances (AHS) are defined as an important components of organic matter, being composed as small molecules in a supramolecular structure and can interact with metallic ions, thereby altering the bioavailability of these species. To better understand this behavior, AHS were extracted and characterized from Negro River, located near Manaus city and Carú River, that is situated in Itacoatiara city, an area experiencing increasing anthropogenic actions; both were characterized as blackwater rivers. The AHS were characterized by 13C nuclear magnetic ressonance and thermochemolysis GC-MS to obtain structural characteristics. Interaction studies with Cu (II), Al (III), and Fe (III) were investigated using fluorescence spectroscopy applied to parallel factor analysis (PARAFAC) and two-dimensional correlation spectroscopy with Fourier transform infrared spectroscopy (2D-COS FTIR). The AHS from dry season had more aromatic fractions not derived from lignin and had higher content of alkyls moities from microbial sources and vegetal tissues of autochthonous origin, while AHS isolated in the rainy season showed more metals in its molecular architecture, lignin units, and polysacharide structures. The study showed that AHS composition from rainy season were able to interact with Al (III), Fe (III), and Cu (II). Two fluorescent components were identified as responsible for interaction: C1 (blue-shifted) and C2 (red-shifted). C1 showed higher complexation capacities but with lower complexation stability constants (KML ranged from 0.3 to 7.9 × 105) than C2 (KML ranged from 3.1 to 10.0 × 105). 2D-COS FTIR showed that the COO- and C-O in phenolic were the most important functional groups for interaction with studied metallic ions.
