Title

EFFECT OF FENTON’S REAGENT ON DEGRADATION OF ANTHRACENE, FLUORENE,NAPHTHALENE AND PHENANTHRENE MIXTURE IN SOIL

Abstract

A good number of PolycyclicAromatic Hydrocarbons (PAH) have been identified to be carcinogenic in nature and their bioavailability has become a matter of serious concern. Soil is the receptor of large number of aromatic hydrocarbons where from the bioavailable ones enter the living kingdom and continue its bioaccumulation and bio magnifications. It starts its detrimental effects as soon as it crosses the permissible level. Since PAH are of recalcitrant natureand hydrophobic, there is the chance of adsorption of these on soil, sediments etc. in water bodies. As such soil and sediments in river bed are prone to be a storehouse of persistent PAH in areas where river water carries effluents especially from refineries,oilfields, coal fields etc. The biodegradation process is a process of oxidation. In the present experiment, the influence of an eco friendly oxidizing agent Fenton’s Reagent (FR) on a mixture of four PAH viz. Anthracene(ANT), Fluorene(FLN), Naphthalene(NPH) and Phenanthrene(PHN)placed in river bed soil is examined in a 60 days experiment. The experimental soil samples are taken from river bed of the river Brahmaputra in the district of Dhubri, Assam, India. A few important physico-chemical parameters of the soil were monitored before placement of measured quantity of PAH. pH is measured at every 20 days of the experimental period. It has been found that the texture of the experimental soil is Loamy sand; deficient of organic carbon compared to agricultural soil and possesses slightly alkaline soil reaction. Gravimetric determination of the soxhlet extracts shows that the extent of degradation in samples where FR was applied in the reagent ratio of H2O2 : FeSO4 = 10:1 is more compared to samples without applied FR. From the GC chromatograms, it has been seen that the mechanism of degradation in presence of FR is quite different from without FR. In a 34 minutes GC analysis, where 50 prominent peaks were recorded in the chromatograms; the samples with FR has only 12,7 and 7 common peaks with the sample without FR in the soxhlet extracts of 0, 20and 40 days respectively.On the other hand, the number of common peaks in the samples without FR is more compared to number of common peaks in samples with FR indicating lower rate of degradation in absence of FR.It has been assumed that concentration of ferrous ions in the 10:1 reagent ratio is not high enough to scavenge hydroxyl radicals which would reduce degradation efficiency of FR
