Special Issue Information

Dear Colleagues,

Inorganic and organic compounds are an essential part of our daily life. However, the careless use of chemicals can be dangerous, generating toxic agents that have a negative impact on health and the environment.

An increasing number of toxic agents (heavy metals, polycyclic aromatic hydrocarbons, pesticides, xenobiotics) provided by industrial activities, waste storage, agricultural activities and traffic from large urban centres cause air pollution or enter into the aquatic environment and are absorbed into aquatic organisms. In recent years, the interest and attention of the scientific community for the development of improved analytical methods and techniques for the analysis and removal of pollutants have increased.

At the same time, a major concern of the current scientific community is the monitoring of traces of these pollutants, including organic, inorganic, radioactive, and biomolecules. Consequently, innovative methods for the determination of trace amounts of heavy metals, anions, and organic compounds are needed, including methods that do not generate toxic by-products or poisonous residues.

An important role in human health and toxicology studies is the balance between environmental pollutants and antioxidant defences in biological systems. Therefore, the toxic effect of pollutants can be assessed under stressful environmental conditions, especially due to the oxidative damage induced by different classes of chemical pollutants.

Based on these considerations, this Special Issue aims to attract high-level research in the field of removing toxic agents from water, air, soil, with the aim of protecting the environment and human health.

Abstract
The arsenic adsorption performance of silicon (Si), iron (Fe), and magnesium (Mg) mixed hydrous oxide containing a Si: Fe: Mg metal composition ratio of 0.05:0.9:0.05 (SFM05905) was investigated. SFM05905 was synthesized by the co-precipitation method. Batch experiments on arsenic adsorption were conducted at [...] Read more.
The arsenic adsorption performance of silicon (Si), iron (Fe), and magnesium (Mg) mixed hydrous oxide containing a Si: Fe: Mg metal composition ratio of 0.05:0.9:0.05 (SFM05905) was investigated. SFM05905 was synthesized by the co-precipitation method. Batch experiments on arsenic adsorption were conducted at various temperatures and concentrations. Adsorption isotherms models were represented by a linearized equations and were insensitive to temperature change. The anion selectivity of SFM05905 at single component was high for arsenite (III), arsenate (V), and phosphate (PO4), indicating that PO4 inhibits arsenic adsorption. The adsorption amount of As (III), As (V), and PO4 were compared using a column packed with granular SFM05905, and an aqueous solution was passed by a combination of several anions that are single, binary, and ternary adsorbate systems. As (III) had the highest adsorption amount; however, As (III) and PO4 were affected by each other under the ternary mixing condition. Although the adsorption amount of As (V) was smaller than that of As (III), it was not affected by other adsorbates in the column experiments. Finally, although the adsorption of both arsenic continued, the adsorbed PO4 gradually desorbed. Full article
