Characterization of humic substances isolated from thermal water and surface water was carried out by elemental analysis and electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry. Atomic ratios derived from elemental analysis represented compositional differences of humic substances. Hydrogen-to-carbon and oxygen-to-carbon atomic ratios were also calculated from molecular formulae determined by ultra high-resolution mass spectrometry. The van Krevelen diagram was used to illustrate the bias between the atomic ratios from elemental analysis and mass spectrometry.
通过元素分析和电喷雾电离傅里叶变换离子回旋共振质谱法对从温泉水和地表水中分离出的腐殖质进行了表征。元素分析得出的原子比代表了腐殖质的成分差异。氢碳比和氧碳比也根据超高分辨率质谱法测定的分子式进行了计算。利用范克雷维伦图来说明元素分析和质谱分析所得原子比之间的偏差。
