Effect of some organic compounds on the mobility of some trace metals through soil amended with fly ash

The effects of some organic compounds, viz. formic acid, acetic acid, metha nol, ethanol, formaldehyde, acetaldehyde, acetone and ethyl methyl ketone o n the mobility of some trace metals, viz. Co, Zn, Cu, Ag and Pb through soi l amended with fly ash have been investigated in an alkaline fine sandy loa m soil of Aligarh district (U.P.). The results indicate decrease in the mob ility of trace metals with increasing dosage of fly ash in soil but with a variation in intensity by use of organic compound as a mobile phase. The mo bility order is Co > Zn > Cu > Ag > Pb in case of organic acids and alcohol s, and Co > Cu > Zn > Ag > Pb for aldehydes and ketones. The effect of orga nic chemicals on the translocation of metals follows the sequence : formic acid > acetic acid > methanol > acetone > formaldehyde > ethyl methyl keton e > acetaldehyde > ethanol.
