This research used different types of ultraviolet–visible (UV–vis) spectroscopy analysis technologies, including differential log-transformed spectra coupled with spectral slope calculation, and two-dimensional correlation spectroscopy (2D-COS) analysis to investigate the binding characteristics between Pb and DOM in the presence of Zn and Cu, respectively. The results indicate that the addition both of Zn 2+or Cu 2+can reduce the binding of DOM to Pb 2+, with the effect of Cu 2+being the most obvious. Specifically, significant changes were evident in the differential log-transformed absorbance at higher Zn2+/Cu2+ concentrations, including modified spectral shapes, absorption wavelength fluctuation, and differential absorption intensity changes. The differential log-transformed absorbance spectral slopes (∆S350-400) exhibited a positive correlation with the predicted NICA-Donnan model value in a wavelength range of 350–400 nm. This suggested that ∆S350-400 served as an indicator for assessing the complexation characteristics of Pb and DOM binding in the presence of Zn2+ and Cu2+, respectively. The 2D-COS spectral results showed that the presence of Zn2+/Cu2+ changed the binding order of the DOM functional groups in response to Pb2+. This study revealed that Zn2+ and Cu2+ competed with Pb2+ for complex sites on the DOM surface in different ways, altering the ability of Pb2+ to bind with DOM. The results suggest that using differential log-transformed spectroscopy combined with ∆S350-400 and 2D-COS analyses is a promising approach to understanding the mechanisms of Zn2+/Cu2+ effects on Pb-DOM interactions, which may provide new insights into the prevention, control, and remediation of environmental Pb pollution.","PeriodicalId":16974,"journal":{"name":"Journal of Saudi Chemical Society","volume":"29 1-2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44442-025-00001-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
