Special Issue Information

Dear Colleagues,

Environmental pollutants such as heavy metals and organic contaminants are discharged in a huge quantity from industries and agriculture. On the other hand, medical drugs such as antimicrobials are used for the therapeutic treatment of diseases in humans and animals such as cattle, swine, poultry, and fish for growth promotion. Today, as a consequence of the overuse of chemicals in agriculture, industries, and uprising of prescription medicines as polar molecule pollutants in the aquatic environment, we have been placed in a more hostile environment with many hazardous materials, whose impact on the local environment is omnipresent. This phenomenon has led to concerns because these discharged contaminants, including pharmaceuticals, can persist in the environment and be ingested either via the food chain or via drinking water in the long run. We cannot emphasize the importance of the removal potency of adsorbents too much. Consequently, the detection, investigation of their environmental behaviors, and removal using different quality materials have become a strikingly urgent issue.

The main objective of the issue is to motivate international experts to focus on environmental contaminants. We invite investigators to contribute original research articles as well as review articles that will stimulate the continuing efforts to understand the adsorption mechanisms, transportation, removal technologies, and management related to materials and technologies for the removal of pollutants from soil and water.

This Special Issue discusses recent advances in chemistry, providing examples from research conducted all over the world. Among the topics to be discussed are:

  • Adsorption: batch studies and column studies;
  • Development of advanced nanomaterials with the capacity of removal of a wide range of contaminants;
  • Configuration and molecular simulation of the adsorbates in the adsorbents;
  • Innovation technologies on removal, including clay/biochar supported nanomaterials;
  • Novel analytical approaches for the study of natural geochemical and environmental agents;
  • Clay/nanomaterials–microbe interaction and biotransformation of organic contaminants.

An accurate and effective method combining ion chromatography (IC) and inductively coupled plasma optical emission spectrometry (ICP-OES) was applied in this work to qualitatively and quantitatively analyze individual and co-existing iodide (I) and iodate (IO3) at various concentrations. More specifically, a very strong linear relationship for the peak area for the co-existing I and IO3 ions was reached, and a high resolution value between two peaks was observed, which proves the effectiveness of our combined IC-ICP-OES method at analyzing iodine species. We observed lower accessible porosity for the diffusion of both I and IO3 in samples of bentonite clay using IC-ICP-OES detection methods, where the effective diffusion coefficient varied based on the anion exclusion effect and the size of the diffusing molecules. In fact, the distribution coefficients (Kd) of both I and IO3 were close to 0, which indicates that there was no adsorption on bentonite clay. This finding can be explained by the fact that no change in speciation took place during the diffusion of I and IO3 ions in bentonite clay. Our IC-ICP-OES method can be used to estimate the diffusion coefficients of various iodine species in natural environments. Full article
