REMOVAL OF SULFIDE FROM WATER USING ALUMINA

Sulfides can cause the corrosion of pipes and the appearance of unpleasant odors. In drinking water sulfides affect organoleptic properties. Investigation of the adsorption onto various materials is increasing because this process gives the possibility for the use of low-cost adsorbents and it is a relatively simple technique for water treatment. Materials considered as adsorbents should primarily meet conditions such as particle size, porosity, and specific surface area. Due to their characteristics, alumina nanoparticles (A?) have wide application in the ceramics industry, as abrasive material, in heterogeneous catalysis, and as sorbents. As an adsorbent, alumina nanoparticles have extensive application in the removal of undesirable compounds and contaminants from drinking water and wastewater. Alumina with a high content of aluminum oxide was used as an adsorbent to remove sulfides from aqueous solutions. This paper aims to examine the possibility of adsorption of sulfide ions onto alumina with a very high content of aluminum oxide (A?). The results of the paper can serve as a starting point for further investigation of the adsorption characteristics of alumina, as well as the behavior of sulfides during adsorption on various adsorbents. Experiments in a column packed with alumina were conducted at room temperature. The effect of different initial concentrations and contact time on the sulfide removal efficiency was investigated. The best efficiency is achieved at low initial concentration and short contact time.
