Investigation of Hexavalent Chromium Removal from Aqueous Solution

Abstract

detrimental side effects, chromium (VI) in wastewater must be reduced or eliminated completely. This includes hexavalent chromium. One of the liquids that improved the biosorption of Cr (VI) in this classroom research was water, which was made possible by adding canola oil. When the equilibrium contact period, adsorbent dosage, pH, initial Cr (VI) ion concentration, and physicochemical criteria are met, batch adsorption systems produce best results. You should set each parameter to the following values based on the results: Here are the recommended parameters: a pH of 3, a starting concentration of 10 mg/l, a dosage of 5 g/l of adsorbent, and a contact time of 75 minutes. At full capacity, its adsorption effectiveness was 99%. Our research indicates that an adsorbent with a maximum practical capacity of about 10.67 mg/g is the most economically viable option.
