A facile chemical procedure was utilized to produce an effective peroxy-monosulfate (PMS) activator, namely ZnCo2O4/alginate. To enhance the degradation efficiency of Rhodamine B (RhB), a novel response surface methodology (RSM) based on Box-Behnken Design (BBD) method employed. Physical and properties each catalyst (ZnCo2O4 ZnCo2O4/alginate) were characterized using several techniques, such as FTIR, TGA, XRD, SEM, TEM. By employing BBD-RSM with quadratic statistical model ANOVA analysis, optimal conditions for RhB decomposition mathematically determined, four parameters including dose, PMS concentration, reaction time. The achieved at dose 1 g l-1, dye concentration 25 mg time 40 min, efficacy 98%. ZnCo2O4/alginate displayed remarkable stability reusability, demonstrated by recycling tests. Additionally, quenching tests confirmed that SO4˙-/OH˙ radicals played crucial role in process.

Abstract Zr-metal-organic frameworks (Zr-MOFs) were prepared by a solvothermal method and characterized X-ray diffraction, scanning electron microscopy, thermogravimetry. Zr-MOFs used to remove doxycycline hydrochloride (DOC) from wastewater. According the experimental results, maximum adsorption capacity of DOC within 5 h was 148.7 mg·g −1 . From pseudo-second-order kinetics model, all R 2 values greater than 0.99, which proved that consistent with practice. Freundlich isotherm proceeded via multilayer adsorption. The aforementioned results show have good application prospects for removing
