This study aims to collect information about soil investigation by FTIR. As we know, the FTIR technique is most often used in organic and bioorganic chemistry, while in geochemistry FTIR spectroscopy is not used very often. Therefore, there is a problem with the identification and interpretation of the IR spectra of minerals contained in sediments and soils. The reason for this is a deficiency of data about characteristic wavenumbers for minerals. Therefore, this study reviews and sums up, in one place, published articles that are connected to an investigation of minerals from 2002 to 2021 (based on the Scopus database). Additionally, the present review highlights various analytical techniques (ATR-FTIR, DRIFT, 2D-IR, and SR-FTIR) and discusses some of them for geochemical study. Additionally, the study describes helpful tools in the data pre-processing of IR spectra (normalization, baseline correction, and spectral derivatives).
本研究旨在收集有关土壤傅里叶变换红外光谱（FTIR）调查的信息。众所周知，FTIR 技术在有机和生物有机化学中应用最为广泛，而在地球化学中，FTIR 光谱技术的应用并不常见。因此，在识别和解释沉积物和土壤中所含矿物的红外光谱方面存在问题。造成这种情况的原因是缺乏有关矿物特征波数的数据。因此，本研究回顾并总结了 2002 年至 2021 年（基于 Scopus 数据库）与矿物调查相关的已发表文章，将它们汇集到一处。此外，本综述还介绍了各种分析技术（ATR-FTIR、DRIFT、2D-IR 和 SR-FTIR），并对其中一些技术在地球化学研究中的应用进行了讨论。此外，该研究还描述了在红外光谱数据预处理中（归一化、基线校正和光谱导数）有用的工具。
