An efficient computational technique for solving the Fokker–Planck equation with space and time fractional derivatives
AbstractThis paper presents numerical solutions of the linear and nonlinear Fokker–Planck partial differential equations [FPPDEs] with space and time fractional derivatives through analytical solutions. These are treated by two analytical methods, namely, fractional reduced differential transform method [FRDTM] and fractional variational iteration method [FVIM] followed by some examples. Numerical results obtained by both FRDTM and FVIM are compared with some existing methods in the literature. This comparison shows the supremacy of FRDTM over FVIM and existing methods in terms of accuracy, simplicity and reliability

Degradation of o-Chlorophenol from aqueous solution by electro-fenton process
The study explores the utility of the electro-Fenton
process for the degradation of o-chlorophenol (o-CP)
from aqueous solution. The extent of degradation of o-CP
is found to be a function of applied current, electrolysis
time, concentration of o-CP and concentration of ferrous
ions. Under optimized conditions it is possible to achieve
efficiencies higher than 70%. Accelerating the regeneration
of Fe2+ ions in the electrolyte determines the efficiency
of the process. Addition of goethite as a catalyst in
the medium did not significantly improve the process
efficiency
