This research study was the removal of nickel by Chitosan in Cockel shells. We prepare Chitosan from Cockel shells .And the effect of time and pH were also investigated. We divided our experiment into 3 parts. Part I was the preparation of Chitosan from shells. Part 2 was the study of the effect of pH. The result was the absorption of nickel from Chitosan could work well in base solution and the best pH was 12 making 97.93 %of absorption while the worst was pH8 making 88.08%of absorption. At the last part, it was the study of effect of absorption time. At 10 to 40 minutes. The absorption was constant and it started to increase at 50 minutes making 76% of absorption.
