Fluorescence excitation-emission matrix spectra coupled with parallel factor and regional integration analysis to characterize organic matter humification.
TL;DR: Fluorescence excitation-emission matrix spectra coupled with parallel factor analysis and fluorescence regional integration analysis were utilized, and the projection pursuit cluster (PPC) model was applied to form a suitable index for overcoming the difficulties in multi-index evaluation.

Characterizing the heavy metal-complexing potential of fluorescent water-extractable organic matter from composted municipal solid wastes using fluorescence excitation–emission matrix spectra coupled with parallel factor analysis
TL;DR: Results reveal that mature composts from the MSWs can be used for the remediation of Cu- and Pb-contaminated soils in situ, whereas immature composts can enhance the metal transferability from soil to plant.

TL;DR: In this paper, a percolate and a method for evaluating bioavailability of heavy metals in water polluted by percolates is presented. But the method comprises the following main steps: extracting and purifying a sample, assaying and regulating the concentration of dissolved organic carbon (DOC) in the sample; assaying the heavy metal content of the regulated sample; performing three-dimensional fluorescence spectrum scanning on the regulated samples; performing parallel factor analysis on the scanning data; performing correlation analysis on a sample and a relative component concentration value obtained in the parallel Factor Analysis; and according

Changes in Spectral Characteristics and Copper (II)-Binding of Dissolved Organic Matter in Leachate from Different Water-Treatment Processes
TL;DR: The results showed the impact of the water treatment on the metal-binding ability of various fractions and the modified Stern–Volmer model can be used to fit the quenching data and calculate conditional stability constants (log K) and the % of fluorophores (f %) between DOM and Cu(II).
