Azo dyes and the byproducts of their degradation have the potential to pollute the environment. Natural water bodies experience less sunlight penetration as a result of these effluents being released into rivers and lakes. Because of their hue, the dyes pollute flowers and the aesthetics because...

An acyclic dinuclear metal complex with O4 donor coordination site was prepared and isolated. A polymethacrylate anchored coordination compound turned out to be designed by the combination of azo compound derived from 3-formyl salicylic acid and diazonium salt of 4-aminophenol with methacryloyl...

This study investigates the effectiveness of a combined precipitation and oxidation leaching process in reducing high concentrations of sulphides in tannery effluent from the unhairing bath. First, at precipitation process the influence of operational parameters, such as stirring speeds, pH levels...

The presence of dye pollutants in the aquatic environment, apart from causing aesthetic problems, can also cause health problems. Removal of dye pollutants in industrial wastewater can be done using the adsorption method, which is a simple, effective and low-cost process. Fly ash is a solid waste...

The main purpose of this study is to evaluate the possibility of using a lignocellulosic residue, peanut shells after alkaline activation, as a low-cost adsorbent for the removal of methylene blue dye from aqueous solutions. Adsorption experiments were conducted by varying parameters such as the...

In this study, removal of reactive yellow 145 (RY 145) dyestuff by dry biomass of Ureolytic mixed microorganism culture (UMC), existing in domestic wastewater and various industrial wastewater, was studied. Optimum conditions of adsorption efficiency were tested. For this purpose, studies were...

This study used a biosorbent, derived from processed Prosopis juliflora root powder to treat wastewater and remove lead (Pb), cadmium (Cd), and copper (Cu) ions. The biosorption process was influenced by factors including temperature (25 to 65°C), biomass content (1 to 5 g), pH levels (1.0 to 7.0)...

IIntroducing tannic acid from tea leaves waste as a complexing agent of Fe(III) into photo-Fenton process to prevent Fe(OH)3 precipitation at pH 7, and further to increase photo-Fenton activity in the near neutral pH for Pb(II) photo-oxidation is systematically addressed. The photo-Fenton process...

The biosorption of uranium ions was explored through batch studies employing activated biochar derived from Gracilaria Edulis seaweeds. A chemical synthesis approach utilizing concentrated sulfuric acid created and activated the adsorbent material. SEM and FTIR measurements were used to characterize...

Healthy water is a concern for the world due to rapid population growth and technological advancement. The entry of heavy metals into water as a result of various activities causes water pollution that has persistent effects. In this study, a specially designed electrodialysis cell was used to...

The purpose of this work is to examine the efficiency of the Electro-Fenton process (Fenton oxidation) for the elimination of amoxicillin from simulated wastewater through response surface methodology (RSM). The effect three operating parameters that were selected for this evaluation were...

Electrochemical treatment of wastewater containing p-nitrophenol (PNP) was carried out using a platinum electrode as an anode and biochar-loaded nano zero-valent iron material as the cathode. The prepared biochar loaded nano zero valent iron electrode materials were characterized and analyzed using...

A mesoporous activated carbon was produced from the Azolla Pinnate (AP) seaweed by two-step chemical activation technique using sulphuric acid as activating agent. The adsorption of Acid Brown (AB) from aqueous solutions is examined using the produced carbon (AP). The produced activated carbon...
