Cr(VI) and Fe(III) ions removal condition resource from aqueous solution with borogypsum

The batch removal of Cr(VI) from aqueous solution using low-cost used middle class borogypsum from waste of kutahya emet boric acids plant under different experimental conditions was investigated in this study. Adsorption application used borogypsum, calcined borogypsum, modification with acids and magnetite. These adsorbents worked pH range, ligand measure, contact time, adsorbent measure, heat parameters. These measure made batch methods. The Freundlich isotherm and Langmuir isotherm fitted well to the data of Cr (VI) sorption capacity of borogypsum and borogypsum?s derivative. The researcher benefited from similar studies while working on analytical paramaters in this application. Chromium(VI) is a strong oxidizing agent. Its highly carcinogenicity and mutagenicity effected humans and animals therefore chromium(VI) detection was important in last decades. Whether iron(III) measure behind a specific range of values or upon that so humans healty bad affected this stuation.
