Industrial and municipal wastewater treatment has the potential of providing considerable quantities of freshwater for different purposes. Prior to its usage, heavy metal ions elimination from treated wastewater must be ensured to evade their toxic and severe impacts on the water ecosystem and humans. For this purpose, graphene oxide (GO)/manganese oxide (MnO2) nanocomposite was prepared… Continue reading Investigation of Graphene Oxide (GO)-Manganese Oxide (MnO2) Nanocomposite in Metal Ions Adsorption from Wastewater
Sediments play a fundamental role in the aquatic environment, so that the presence of contaminants poses severe concern for the possible negative effects on both environmental and human health. Sediment remediation is thus necessary to reduce pollutant concentrations and several techniques have been studied so far. A novel approach for sediment remediation is the use… Continue reading Ultrasonic processes for the advanced remediation of contaminated sediments
This research aimed at synthesizing polyethersulfone/α-zirconium phosphate (PES/ α-ZrP) flat-sheet nanocomposite ultrafiltration (UF) membranes. The impact of α-ZrP nanoparticle (NP) addition on the morphology, functionalities, hydrophilicity, and surface charge of the membrane, among others, were investigated. Different concentrations of α-ZrP NPs (0.25, 0.50, 0.75, and 1.00 wt.%) were tested. Membranes surface morphology was investigated by… Continue reading Development of Polyethersulfone/α-Zirconium phosphate (PES/α-ZrP) flat-sheet nanocomposite ultrafiltration membranes
In this study, commercial cellulose membranes were surface coated with alpha‑zirconium phosphate nanoparticles (α-ZrP-n) to study their impact on the overall removal efficiency of heavy metals from synthetic metal mixture wastewater solution. A total of four homogeneous solutions (0.25, 0.50, 0.75, and 1.00 wt%) of α-ZrP-n were prepared by sonicating the nanoparticles in deionized water.… Continue reading Synthesis of super hydrophilic cellulose-alpha zirconium phosphate ion exchange membrane via surface coating for the removal of heavy metals from wastewater
