We have accomplished a synthesized of an adsorption material through anchoring N-(3nitro-benzeyliden)-N-trimethoxysilylpropylethan-1,2-diamin onto multi-wall-carbon nanotube. The systems were established via SEM and FT-IR techniques. Then, it was used for removing the ultra-sound-assisted for Thymol Blue (TB) and Erythrosine-B (EB).The pH dependency and initial dyes concentration, sonication time and adsorbent's dosage for the removing percentage of Thymol Blue and Erythrosine-B which have investigated by CCD or Central-Composite Designing. It was exhibited that the Thymol Blue and Erythrosine-B adsorption follows, while the Langmuir models explain the equilibriums variables.

After synthesizing Ag nanoparticles and loading onto activated carbon (from olive stone), the adsorption of methyl orange (MO) onto the prepared nanoparticles was studied. In this connection, the effect of experimental parameters such as pH range, reagent concentration, contact time, dosage amount of adsorbent and so on, on the adsorption process were studied. The experimental results were analyzed upon various kinetic models such as pseudo first order reaction, pseudo second order reaction, Elovich model, intraparticle diffusion model and various adsorption isotherms such as Langmuir isotherm, Freundlich isotherm and Temkin isotherm.
