Abstract
Our work has a dual environmental aspect. On the one hand a valorization of natural by-products in this case the dates nuclei, and on the other hand, the study of the adsorbent efficiency of the active carbon resulting from these nuclei for the elimination of methylene blue. The various characterization results (activation, pH, concentration, mass, particle size, etc.) have shown that the materials obtained with different concentrations of activated carbon (0, 5, 10 and 15wt. %) mixed with HDPE have a large external surface and a low diffusion depth which generates a very fast adsorption rate. The role of the adsorbent (CA) is the elimination of the pollutant (colorant), this is due to the fact that the diffusion of the molecules of the colorant of the solution on the surface of the adsorbent is accelerated by the increase of the concentration in CA, in our case, by a simple visual appearance, the level of CA that responds to this slight discoloration of methylen blue is 10wt. %. So coal made from date kernels could then be tested for example in HDPE tubes for treatment of water.
