Abstract
In the present work, potato peel waste (PPW) is used as precursor of activated carbon and applied to the removal of sodium diclofenac from synthetic effluents in parallel with a commercial activated carbon (GAC). PPW-based activated carbon (CPPW) was obtained by chemical activation with K2CO3 and submitted to textural and chemical characterization. Diclofenac adsorption experiments were carried out and the optimization of several parameters was performed in order to obtain equilibrium and kinetic data. The
results showed that CPPW and GAC reach the equilibrium around 17 h and 30 h, respectively. The uptake capacities of the two carbons in the equilibrium were very similar. The DCF adsorption isotherms of both carbons were best fitted to Langmuir model; GAC presented the higher adsorption monolayer capacity, but CPPW presented higher affinity to DCF molecule.
