251-255Destructive adsorption of methyl parathion
(MP) has been investigated over few transition metal oxides and alkali earth metal
oxides. Performance of alkaline earth ox ides have been found to be better than
transition metal oxides and best performance has been shown by aerogel method prepared
nanocrystalline AP-MgO. The AP-MgO powder has been
characterized by XRD, AFM and BET
surface area measurements. Destructive adsorption of MP over AP-MgO has been compared
with that of activated carbon. Both are found to adsorb methyl parathion effectively.
An IR investigation of the surface of treated AP-MgO and activated carbon reveals
that activated carbon adsorbs methyl parathion as such in the
molecular form and AP-MgO adsorbs it destructively
