At present work, the rate of biosorption was studied under a variety of conditions, including initial Cr(VI) concentration (5-50 mg/L), amount of biosorbent (0.5-3 g/100 mL), pH (1-8), temperature (298-318 K) and contact time (30-120 min). Biosorption of Cr(VI) is in all cases pH-dependent showing a maximum at equilibrium pH values between 2 and 3. The biosorption data fitted well with Langmuir and Freundlich isotherms. The biosorption capacity calculated from the Langmuir isotherm was q = 33.58 mg Cr(VI)/g of dry seeds (at 303 K). Biosorption kinetics data well fitted using pseudo-second-order. Thermodynamic studies confirmed that biosorption of Cr(VI) ions by mucilaginous seeds of Cydonia oblonga was spontaneous and endothermic nature.</p></abstract><publication_date><month>09</month><day>25</day><year>2017</year></publication_date><pages><first_page>269</first_page><last_page>277</last_page></pages><publisher_item><identifier id_type="pii">gnest_01708</identifier></publisher_item><doi_data><doi>10.30955/gnj.001708</doi><timestamp>1713571914</timestamp><resource>https://journal.gnest.org/publication/gnest_01708</resource></doi_data></journal_article></journal></body></doi_batch> </div>
