Chitosan and its Modified synthetic forms for sulphate removal in Aqueous media - Free Essay Example

Adsorption is one of the process commonly used in the removal of sulfate ions in their aqueous state by using hydrotalcite-like composite as the adsorbent through the process called co-precipitation method. The elements are used to clarify the structure and compounds found in the adsorbent for the removal process to be successful. Hydrotalcite-like composite is used as the adsorbent for the removal of sulfate ions through precipitation method in the aqueous solution. The primary analysis is used to make clear the structure and composition of the hydrotalcite-like composite. The impacts of time, the original PH content, and ions on the adsorption performances has to be examined. The outcome indicated that the material composed of the zinc aluminum nitrate Hydrotalcite –like compounds and zinc aluminum phenylalanine Hydrotalcite –like compounds. The Hydrotalcite-like composite has an excellent ability to remove the sulfate ions with a real capacity which is highly recommended in the process of ion removals. From the analysis, it’s true that the chemical adsorption was the limiting factor in the whole process thus the Freundlich isotherm was the best in explanation of the adsorption process. This shows that the use of hydrotalcite-like the composite to remove sulfate ions was passing through different layers for the process to be more efficient. Thermodynamic measures show that the proceeds generated a lot of heat within and unexpected heat at normal temperature. Hydrotalcite-like composite in the experiment, therefore, removes the sulfate ions through the ion exchange process with the help of the electrostatic force which separates the ions and also by use of physical adsorption. From the procedural results, it’s evident that hydrotalcite-like composite was capable of removing sulfate ions in the aqueous solution. This process is the most suitable for the removal of sulfate ions compared to others as the process is endothermic.
