Advances in the Synthesis and Modification of Low-Cost-Based Adsorbents for Water Treatment

Dear Colleagues,

Most of the waste produced due to industrial activity may be dumped into the environment without first being treated. This waste contaminates the freshwater supply with various toxins, including fluoride, oils, dyes, medical waste, metal ions, and other substances. The problem of rising water pollution from these pollutants is an obvious global environmental concern because of the toxicity of these contaminants when present in amounts beyond what is permissible. Due to these issues, the toxins from industrial processes must be eliminated before they enter freshwater. It is possible to eliminate a significant amount of these contaminants by using inexpensive materials. To successfully remove pollutants from aqueous solutions, it is necessary to investigate the creation of novel materials and feasible removal methods. The synthesis of low-cost-based adsorbents such as naturally available silica source materials, clays, layered hydroxide materials, biowastes, biomass, algae, etc., during the last several decades has permitted various applications, including wastewater treatment. The synthesized or modified adsorbents should be cost-effective and highly efficient. For material synthesis, the low-cost procedures that are described in the accessible research literature and the low-cost techniques that are currently being developed were used. In addition, more efficient modification of materials that can be used in procedures with low costs might be produced, which would be advantageous for water purification. As a result, there is a significant amount of continuing research into useful, cost-effective materials that may be employed as high throughput materials in wastewater treatment. The focus of the study may involve the synthesis of materials using very inexpensive processes and high removal efficiency.

This Special Issue will investigate developments regarding synthesizing and modifying low-cost adsorbents that remove contaminants and innovative techniques that balance environmental health and economic concerns. Surface modification, the properties of turned materials, removal techniques for the different treatments under investigation, high adsorption capacity and fast removal are all areas of interest. Potential topics include, but are not limited to the following: naturally available materials, clay materials, silica-based materials, surface-modifed adsorbents, high removal efficiency, synthesis and modification , adsorption process, pollutant removal, adsorption mechanism, rapid removal contaminants and selectivity-based removal.
