Using a bipolymer system consisting of polyvinylpyrrolidone (PVP) and poly(vinylidene fluoride) (PVDF), P25-TiO2 was immobilized into thin film mats porous electrospun fibers. Pores were introduced by dissolving sacrificial PVP to increase surface area enhance access TiO2. The highest photocatalytic activity achieved using PVDF:PVP weight ratio 2:1. Methylene blue (MB) used visualize contaminant removal, assess the sorption capacity (5.93 ± 0.23 mg/g) demonstrate stable removal kinetics (...
In this study, we explored the adsorption potential of biochar derived from palm kernel shell (BC-PKS) as an affordable adsorbent for removal crystal violet wastewater. Kinetics, equilibrium, and thermodynamics studies were carried out to evaluate onto BC-PKS. The kinetics process followed pseudo-second-order model, indicating that rate is principally controlled by chemisorption. equilibrium data better fitted Langmuir isotherm model with a determination coefficient 0.954 maximum 24.45 mg/g....
We assessed the applicability of rice husk (RH) to remove cationic dyes, i.e., methylene blue (MB) and crystal violet (CV), from water. RH thermally treated at 75 °C showed a higher adsorption capacity than that high temperatures (300–700 °C). For suitable CV-adsorption model, pseudo-first-order model for MB was followed by kinetics process; however, pseudo-second-order then suggested. In qt versus t1/2 plot, line passed through origin, but CV did not. The Langmuir isotherm better Freundlich...
UV/H<sub>2</sub>O<sub>2</sub> is a commonly used advanced oxidation process for removing non-biodegradable organic compounds. However, additional efforts are needed to understand the relative significance of operational factors during UV/H<sub>2</sub>O<sub>2</sub>. Here, we investigated effect and specific contribution crucial such as H<sub>2</sub>O<sub>2</sub> concentration, UV intensity, reaction time on color total...
Micrometer-sized titanium dioxide hierarchical spheres (TiO2-HS) were assembled from nanosheets to address two common limitations of photocatalytic water treatment: (1) inefficiency associated with scavenging oxidation capacity by nontarget constituents and (2) energy-intensive separation recovery the photocatalyst slurry. These micrometer-sized are amenable low-energy separation, over 99% recaptured both batch continuous flow reactors using microfiltration. Using as building blocks resulted...
