Hexavalent chromium removal from a simulated wastewater using Fe(II) modified bentonite
Background and Objective: Hexavalent chromium is reported to be highly toxic, mutagenic and carcinogenic; hence treatment of water and wastewater contaminated with this element by low-cost and environmentally friendly methods is of great importance. Therefore the aim of present study was to evaluate the efficiency of Fe(II) modified bentonite for hexavalent chromium removal from a simulated was...
متن کاملکاربرد پودر معمولی گل گیاه تلخه به عنوان جاذب بیولوژیکی طبیعی در حذف کروم شش ظرفیتی از فاضلاب سنتتیک
Background: One of the most recent concerns about industrial wastewaters is heavy metals arrival into the water and environment resources. Chromium is found in the trivalent and hexavalent oxidation state by the influence of electroplating and tannery industries. Hexavalent Chromium has proven several health hazards and International Agency for Research on Cancer (IARC) categories. The aim of ...
متن کاملApplication of modified bentonite using sulfuric acid for the removal of hexavalent chromium from aqueous solutions
Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...
متن کاملRemoval and transformation of hexavalent chromium in sequencing batch reactor
The objectives of this study are to evaluate the efficiency of removal of hexavalent chromium (Cr(VI)) in a sequencing batch reactor (SBR) and to ascertain the fate of Cr(VI) in the treatment process. An SBR was operated with the FILL, REACT, SETTLE, DRAW and IDLE periods in the time ratio of 2:12:2:1.5:6.5 for a cycle time of 24 h. The study was divided into 5 phases with the addition of 0.5, ...
متن کاملHexavalent chromium removal in a tannery industry wastewater using rice husk silica
Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in the tannery indust...
