Abstract:
Chitosan is a good absorber for removing cationic and anionic dyes as well as the removal of heavy metals ions. Chitosan and bio polymers is used for water purification and sterilization in recently years, for removal some materials that are harmful for human body even at low concentrations. Chitin is one of the most materials in the earth extract from crustacean shell such as prawns ,crabs ,shrimp ,fungi and other crustaceans chitosan has a certain reputation for many reason like:absorption properties, no toxicity, ability to decomposition . stabilize of enzymes .The use of chitosan have a high speed and is an economically and efficiently. chitosans are for separation of materials such as copper, zinc ,chrome ,iron nickel ,cadmium ,mercury that isdebated mechanism to coordinate the metal ions with an amino group.Each of the ions separate in special conditions that related to elements like: ion adsorption on the surface ,chemical absorption ,PH, rate mix ,temperature ,concentration.
