Abstract: A self-adaptive surface absorption spectrum analysis method, comprising the following steps: obtaining spectrum data (S1), extracting a blank spectrum (S2), and analyzing and processing an absorption spectrum (S3). The present invention relates to a self-adaptive surface absorption spectrum analysis system, an electronic device, and a storage medium. A sample surface reflection spectrum diagram only needs to be collected once in the measurement process, and reflected light of a reference object is not required to be collected before measurement as the blank spectrum; due to the fact that a fitting blank spectrum curve comprises a same substrate absorption band in the sample surface absorption spectrum, the analysis method can eliminate a quantitative error caused by absorption and superposition of a substrate. By synchronously extracting the blank spectrum in real time from a sample reflection spectrum, the analysis method can adapt to a change of the distance between a sample and an optical probe and a difference of different sample matrix components, thereby realizing more accurate quantitative analysis of a narrow-band characteristic absorption peak in the sample.
