Silver nanoparticles were synthesised and used as a nano-adsorbent. Silver nanoparticles were added to adsorption system contain a (walnut husks – Manganese ions). The concept of this addition is to enhance the adsorption system due to high surface area to volume ratio of silver nanoparticles. Characterization of walnut husks was done by Fourier transformation infrared (FTIR). Characterization of silver nanoparticles was done also using many techniques, dynamic light scattering (DLS) and field emission scanning electron microscopy (FE-SEM) were used for determination of size and the potential of silver nanoparticles and also to identify the size and the shape of silver nanoparticles. The image showed an average particle diameter in the range (10-85 nm). Energy dispersive X- ray spectra (EDS) was used to examine the quantity of prepared silver nanoparticles. The optimum parameters were studied for this adsorption system such as contact time, weight of adsorpant, effect of pH, manganese concentration and the effect of addition of silver nanoparticles on the (walnut husks –Mn (II) ions) adsorption system. All the experiment parameters were fixed then silver nanoparticles were added to the system contain (walnut husks - Mn (II) ions). The results showed enhancement in the percentage of releasing by 2.2%. The data of the experiment has been investigated through Langmuir, Ferndelsch and Temkin. By evaluating the results, it can be concluded that the adsorption isotherm is most distinct through Freundlich.
