The object of research is bentonite clays, the main rock-forming mineral of which is montmorillonite. This natural silicate exhibits sorption capacity for heavy metal ions due to its high cation exchange capacity and specific surface area. One of the most... see more

The knowledge of the mechanism involved in the process of adsorption and desorption of arsenate and arsenite with ferric hydroxides is important to address the water toxicity problems and to tackle the adverse effect of these substances in nature. An esse... see more

Iron oxide nanoparticles were made using celery extract by chemical method with change PH. Bio-materials in celery extract synthesized the iron oxide nanoparticles by reducing iron (III) chloride (FeCl3) and then acted as both capping and stabilizing agen... see more

The voluntary or accidental release of chemical compounds in the environment is a major cause of pollution of natural waters. Most of chlorophenols are toxic and hardly biodegradable and are difficult to remove from the environment. Therefore, it is impor... see more

Heterogeneous photodegradation of Linuron under UV irradiation was investigated. Natural iron oxide (NIO) was used in this study, to take a closer look at its adsorption capacity in the dark. The results obtained showed that the substrate photolysis is ve... see more

A heterogeneous photo-Fenton-like degradation process of 1-naphthol (1-NP) promoted by natural iron oxide (NIO) in the presence of H2O2 was studied under artificial (365 nm) and solar irradiation. This is an important reaction for the environment since bo... see more

In this work, the methylene blue (MB) heterogeneous photodegradation was investigated in the natural iron oxide (NIO) and oxalic acid process under UV irradiation. The adsorption of MB onto the surface of NIO was found favorable by the Langmuir approach. ... see more
