Abstract This study demonstrated that Moringa oleifera seed biomass (MOSB) has the potential to be used as a natural alternative in removal of lead (Pd), cadmium (Cd), and copper (Cu) from water which was justified by level toxicity, environmental unfriendliness, costly nature chemical coagulants presently used. The Fourier Transform Infrared (FTIR) analysis identify MOSB functional groups pres...

The application of simultaneous adsorption and biodegradation processes in the same reactor is known to be effective in the removal of both biodegradable and non-biodegradable contaminants in various kinds of wastewater. The objective of this study is to evaluate the efficacy of the two processes under sequencing batch reactor (SBR) operation in treating copper and cadmium-containing synthetic ...

Wastewaters containing Cu(II) along with ligands are ubiquitous in various industrial sectors. Efficacy of treatment processes for copper removal, especially precipitation, is greatly debilitated by ligands. Chemical reduction being commonly employed for production of metal nanoparticles has also been used for removing copper. Addition of ammonia was reported to be essential for improving coppe...

The aim of this study was to investigate the chemical modifications of coal fly ash (CFA) treated with HNO3 or ammonium acetate (AcNH4) or NaOH or sodium diethyldithiocarbamate (NaDDTC) as an adsorbent for the removal of copper(II) and zinc(II) ions from aqueous solution. The morphology of fly ash grains before and after modification was examined via X-ray diffraction (XRD) and images of scanni...

The present study investigates an NF process for removal of copper and hexavalent chromium, studying the effect of pH (5, 7, 9) as well as contaminants' concentration (50, 500, 5000 µg/L) at a constant pressure of 8 bar; with the recovery rate, regulated at 75±2%. To determine the main factors, affecting the system performance, and evaluate the interaction effects among the factors, the experim...

A new 3D porous anionic MOF (AMOF-1) based on Zn(II) and a flexible tetracarboxylate linker has been synthesized. AMOF-1 showed potential for capture and removal of toxic metal ions from aqueous solution with a detection limit in the ppm level. The Cu(II)@AMOF-1' hybrid obtained by post-synthetic metalation is studied as a heterogeneous catalyst for the synthesis of benzimidazole derivatives.
