Abstract :The present study was aimed at determining whether walnut shell would have acceptable adsorption efficiency for removing Ni insert ignore into journalissuearticles values(II); and thereby offer an effective and economical alternative to more expensive treatments. This paper describes the removal of Ni insert ignore into journalissuearticles values(II); ions from aqueous solutions containing 100 mg L -1 of nickel using walnut shell. The effects of various parameters such as optimum adsorbent mass, contact time, pH of the medium were investigated. The maximum removal efficiency of 43.23% was obtained at a pH of 5.85 with a 5-min contact time for a 5 mg L -1 solid-to-liquid ratio and an initial heavy metal concentration of 100 mg L -1 . it can be concluded that walnut shell could be used as a low-cost and abundant source for the removal of Ni insert ignore into journalissuearticles values(II);, and as an alternative to more costly materials such as ion-exchange resins and activated carbon. It is thought that it will be possible to make walnut shell modification studies in order to obtain higher increases in recovery efficiency.
