In recent years, the preparation of low cost adsorbents as an alternative for the removal of toxic heavy metals from the waste water. Now a days, various natural adsorbent have been used by many researchers as a cheaper method for the treatment of water. The toxic heavy metals are released in the environment; due to rapid industrialization and urbanization possess a great threat to environment. Adsorption is an effective technique for the removal of heavy metals from the aqueous solutions. In this work adsorbent is prepared chemically from the fruit of Kigelia pinnata as a measure to control the environmental pollution. The studies are carried out to remove the Zinc (II) ions from the aqueous solutions The chemically activated carbon was characterized using standard American Standard Testing Methods. (ASTM). Adsorption studies were performed by batch experiments showed that the adsorbent prepared from the fruit of Kigelia pinnata (KP) has a good capacity of adsorption of Zinc (II) ions from aqueous solution. The parameters study includes contact time, adsorbent dosage, initial concentration, and pH. The adsorption of zinc ions was tested with Langmuir and Freundlich isotherm models.
