Kinetic Study Of Biosorption And Bioreduction Of Hexavalent Chromium By Unmodified Sawdust
The effects of initial Cr(VI) concentration, initial pH and sawdust dosage on Cr(VI) biosorption-bioreduction were evaluated at the initial Cr(VI) concentration range of 250 -1500 μM, pH range of 2.0 - 4.0 and dosage range of 2 – 4 g L-1, respectively. The effects of phenol and Zn(II) were evaluated...
