摘要

傅里叶变换红外光谱是一种对传统分馏和提取方法的补充，可用于土壤有机质(SOM)的研究。本文综述了漫反射红外傅里叶变换(DRIFT)在中红外区域(MIR: 4000-400 cm−1)中的应用。本文综述了漂移光谱的两种不同应用:土壤有机质(1)表征和(2)定量。SOM的表征包括对构成有机物的官能团进行定性到半定量的测量，而定量则采用化学计量学来预测SOM的组分。提供了如何根据样本类型和研究问题进行方法决策的指导，以及对结果的解释。

Fourier‐transform infrared spectroscopy for soil organic matter analysis

Abstract The study of soil organic matter (SOM) can benefit from the use of Fourier‐transform infrared spectroscopy, an analytical method that complements traditional fractionation and extraction methods. This review provides guidance on the use of diffuse reflectance infrared Fourier transform (DRIFT) in the mid‐infrared region (MIR: 4000–400 cm −1 ). Two distinct applications of DRIFT spectroscopy are reviewed: soil organic matter (1) characterization and (2) quantification. Characterization of SOM involves the qualitative to semi‐quantitative measurement of functional groups that constitute organic matter, and quantification employs chemometrics to predict fractions of SOM. Guidance on decision‐making in how methods are conducted based on sample type and research question, and on interpretation of results are provided.
