Studies on the removal of mercury (II) - EDTA complex by adsorption on coal and coal flyash blends have been carried out at 30 degree C. The effect of various parameters on the extent of removal of Hg2+-EDTA complex has been determined.

Investigation on the removal of formic acid (FOA) by adsorption on flyash-wood carbon (FA-WC) blends has been made  under batch mode. The adsorption data on the variation of (i) initial concentration of acid, (ii) contact time (iii) does and (iv) particle size of FA-WC are determined.
