Performance of Fe‐loaded chitosan carbonized rice husk beads (Fe‐CCRB) for continuous adsorption of metal ions from industrial effluents

Abstract: The present investigation elucidates the removal of heavy metal ions using Fe‐loaded chitosan carbonized rice husk beads—Fe‐CCRB from synthetic and industrial effluent in a fixed bed column. The surface properties of Fe‐CCRB were characterized by Brauner Emmet and Teller (BET) analyzer, Scanning Electron Microscopy (SEM), Energy Dispersive X‐ray Analysis (EDAX) and Fourier transform infrared spectroscopy (FTIR). The effects of process parameters such as flow rate, bed height and initial Cr (VI) concentration w… Show more

“…41 filter paper. The concentration of unadsorbed Cr(VI) ions in the reaction medium was determined spectrophotometrically at 540 nm using a double beam UV-visible spectrophotometer (2201, Systronics) after complexation with 1,5-diphenylcarbazide in an acidic medium [25]. The biosorption capacity q e (mg g -1 ) was calculated using the below equation.…”

“…Cr(III) is essential for proper functioning of human metabolism especially in glucose and is relatively immobile and innocuous . The chromium problem is mostly related to its hexavalent form, because of its high toxicity to living organisms . The Cr(VI) has high water solubility and mobility over almost the entire pH range.…”
