Oxidation Degradation of Rhodamine B in Aqueous by UV/S2O8 2− Treatment System
Published 2012-01-01“…The effect of oxidant S2O8 2− concentration, initial dye concentration, initial pH of solution, and various inorganic anions (Cl−, H2PO4 −, and HCO3 −) were investigated using Rhodamine B (RhB), a kind of xanthene dye, as a model pollutant. With the increase of oxidant S2O8 2−, more SO4 •− produced to attack RhB molecules and result in the increase of RhB degradation. …”

Temporal variability of dissolved inorganic nitrogen and key environmental drivers in a dam-induced subtropical urban lake
Published 2025-02-01“…Random Forest modelling indicated that the temporal variations in DIN concentration were closely related to the notable seasonal fluctuations in key water quality indicators such as the temperature (T), Secchi depth (SD), and concentrations of dissolved phosphorus (DP), dissolved silica (DSi), chlorophyll-a (Chl-a), which were predominantly attributable to hydrological alterations associated with reservoir management and external pollutant inputs from agricultural fertilization. Partial Least Squares Path Modeling confirmed that physical indicators, like T and SD, were the primary drivers of variations in DIN concentration, while DP, DSi, and Chl-a also had significant effects. …”
