Solid phase extraction (SPE) is extensively utilized for the extraction of dissolved organic matter (DOM); nevertheless, the efficiency of SPE under specific conditions (employing formic acid as the acidifier, hydrophilic-lipophilic balance (HLB) as the sorbents, and methanol as the elution solvent) remains unclear. In this study, 13 refuse leachate samples, 10 effluent samples after leachate treatment, and 14 surrounding groundwater samples from 13 landfills were collected. The excitation and emission matrix was employed to analyze the stock solution, eluent, and permeate before and after SPE, enabling the evaluation of DOM enrichment and loss during the extraction process. The results indicated that this SPE method could effectively extract fulvic acids with short emission wavelengths from leachate and aromatic proteins from treated effluent and groundwater. However, but it exhibited low efficiency in recovering large humic acid molecules. This inefficiency might be attributed to the incapability of formic acid to effectively protonate these components. Parallel factor analysis indicated that the method preferentially extracted structurally simple tryptophan-like proteins, while its performance for humic acids was restricted. The SPE method involving formic acid acidification, HLB cartridge adsorption, and methanol elution effectively separates and extracts structurally simple and hydrophilic DOM. These results provide a valuable reference for further elucidating the characteristics of low-molecular-weight, hydrophilic chlorinated DOM.
