REMOVAL OF Cr(VI) IONS FROM REAL SYSTEMS USING CLAYEY DIATOMITE AS AN ADSORBENT
Keywords:
Cr(VI), adsorbent, real systems, clayey diatomiteAbstract
Pollution with heavy metals in water resources is a serious environmental problem, especially the pollution with Cr(VI), so it is very important to enable their efficient removal from contaminated waters. The removal of Cr(VI) from wastewaters is a necessity because of its toxicity for the living beings and the environment. In this research we focused on the new ways of removal of Cr(VI) ions from aqueous solutions using natural inorganic material, clayey diatomite which originates from Bitola. Results from the spectrophotometric analysis gave us insight for the initial concentration of Cr(VI) and concentration after adsorption. The adsorption experiments were performed at constant room temperature, with 0.5 mg/l initial Cr(VI) ions concentrations, adsorbent amount of 2.5 g/l and pH of the solution 3. Low costed Clayed diatomite, can be successfully applied as an adsorbent for the removal of Cr(VI) ions from wastewater
