The present investigation entails the application of dry cow dung powder (DCP) as an indigenous, inexpensive and eco-friendly material for the removal of Cr(VI) from aqueous medium. Batch biosorption experiments were conducted employing 51 Cr(VI) as a tracer and the effect of various process parameters such as optimum pH, temperature, amount of resin, time of equilibration, agitation speed, concentration of metal ions and interfering effect of different salts etc. were studied. The kinetic studies were carried out employing various models but the best fitting was given by Lagergren Pseudo-second order model with high correlation coefficient R 2 value of 0.997 and adsorption capacity of 10.20 mg/g. The thermodynamic parameters for biosorption were evaluated as ΔG • = −2.837 kJ/mol, ΔH • = −4.757 kJ/mol and ΔS • = 16.64 J/mol K, which indicated spontaneous and exothermic process with high affinity of DCP for Cr(VI). Many naturally available materials are used for the biosorption of heavy metal pollutants, where most of them are physically or chemically modified. In this research work, DCP has been utilized without any pre or post chemical treatment. Thus it manifests the principle of green chemistry and proves to be an eco-friendly resin.

“…DCP (100 mesh) was provided by Keshav Shrushti, Research centre on Cow product (Thane, India) and due precautions were taken to avoid any contaminations. The HA has been successfully extracted by authors from DCP and this piece of work has been published in the International Journal [14]. DCP after removal of HA was thoroughly washed with distilled water and was dried in oven as guided by standard protocol.…”

To evaluate the bioremediation efficiency of natural humic substances, over it's synthetic counterpart, a comparative batch equilibration biosorption assay have been carried out employing radiotracers on different humiresins. The biosorptive profile of various humiresins as devised hereby, attempts to justify an innovative and concrete role of dry cow dung powder (DCP), in 'as it is form', for the bioremediation of metal pollutants such as Cr(III), Cr(VI), Cd(II), Hg(II) and Sr(II). Our comparative results conclude that, with all other optimized parameters as obtained 100 mg of DCP removes Cr(III) at pH 6, Cd(II) at pH 3 and Hg(II) at pH 3 to 70-75 and 80-85 % respectively. Also, at pH 1 with 250 mg of DCP 70-75 % Cr(VI) is removed. Similarly, 90-95 % of Sr(II) is sequestered at pH 6, with 350 mg of DCP. The study on thermodynamic, kinetic and isotherm modelling of DCP indicates feasible, eco-friendly and efficient process.
