Continuous Separation of Hexavalent Chromium in a Packed Bed of Flyash Pellets

The metal pollutant hexavalent chromium has been separated from flyash. Various types of flyash pellets were prepared by mixing flyash with different binders, such as cement, bitumen, kaolin, etc. Pellets containing 20% (w/w) kaolin were found to have satisfactory separation efficiency. Break through curves for a hexavalent chromium separation process at different bed heights, flow rates, and temperatures were evaluated. It was also observed that Cr (VI) removal in the packed bed increases with an increase in temperature and bed height but decreases with an increase in flow rate. Presence of other competing cations had no significant interference on separation. Desorption of adsorbed Cr (VI) from a packed bed of flyash pellets using H₂SO₄ and NaOH as eluants was also studied; it was found that sulfuric acid has better desorption efficiency. Leaching of Cr (VI) from flyash pellets to an aqueous phase at different temperatures was studied and it was observed that release of chromium (VI) is not a spontaneous process. The extent of leaching was markedly reduced when cement was present in the flyash as binder and temperature has little effect on the leaching. A model for break through curves has been established to co-relate the relative hexavalent chromium separation efficiency of flyash with other variables.

Studies on the effect of titanate coupling agent (2.0%) on the mechanical properties of flyash‐filled polybutadiene rubber

Flyash, a waste product of thermal power stations, generated in huge quantities, has been posing problems of disposal. Attempts have been made for its utilization as a filler in elastomers and plastics; however, it has been established that untreated flyash does not at all contribute in enhancing mechanical properties of composites. The purpose of this work was to make meaningful utilization of flyash as a filler, by treating it with a titanate coupling agent and to use it as a filler in PBR. The properties under consideration were tensile strength, modulus at 100 and 400%, Young's modulus, hardness, etc. Composites were made with varying proportion of untreated and treated flyash. A two‐roll mill was used for dispersing the filler in the rubber, and a compression‐molding technique was used to cure the compound in sheet form. Tensile properties were measured on a computerized UTM using an ASTM procedure. Comparison of properties of composites filled with treated and untreated flyash established that treatment of flyash imparts better reinforcing properties. Tensile strength was improved by 50%, while modulus at 400% was improved by 400%. Similarly, Young's modulus also was improved by 209%. The Titanate‐coupling agent used here has promoted adhesion between flyash and the PBR. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 1293–1298, 2004
