Fractional Calculus is a branch of mathematical analysis that satisfies the possibility of considering the power of the differential operator as a real number. Several different families of fractional derivatives (such as,Riemann–Liouville, Caputo, Hadamard and others) are developed.In this work, we are investigate the applications of the Laplace transform to construct the solution of homogenous and nonhomogeneous

Copolymer(Acrylamide–Bisacrylamide),was prepared, and identified by F.T.I.R. Spectroscopy then swelling tests were performed for this polymer in different solvents.The adsorption processes of some phenolic compounds: ph, DNPh, APh and NPh in aqueous solution on the surface of this polymer were investigated by the use of UV – visible spectrophotometer and also studied at different: PH, temperatures, and ionic strength.Results revealed that the adsorption for compounds
