The purpose of this study was to identify and characterize humic compounds in Anticolana Valley (Fiuggi) water. The capacity of this class of compounds to mobilize metals from solid phases could have an important role in calculi solubilization. Humic compounds were isolated, purified and characterised by FTIR, 1H-NMR and 13C-NMR spectroscopy, thermogravimetry and elemental analysis. Only fulvic acids were found. They are mainly composed of aliphatic chains, made of six -CH2O- groups and contain a number of carboxylic groups, responsible for their metal complexing capacity.
本研究的目的是鉴定和表征安蒂科拉纳山谷（菲乌吉）水中的腐殖化合物。这类化合物从固相 mobilize 金属的能力在结石溶解中可能起重要作用。通过傅里叶变换红外光谱（FTIR）、核磁共振氢谱（1H-NMR）、核磁共振碳谱（13C-NMR）光谱、热重分析和元素分析对腐殖化合物进行了分离、纯化和表征。仅发现了富里酸。它们主要由脂肪族链组成，由六个-CH2O-基团构成，并含有若干羧基，这些羧基决定了它们的金属络合能力。 注：这里“mobilize”根据语境推测可能是“迁移、动员”等意思，但在专业医学文献中可能有特定含义，最好结合完整文献背景理解。
