The widespread use of chitosan waste shrimp extract to reduce the toxicity of certain heavy metals can reduce the escalation of the potential threat of environmental pollution. First) shrimp shell processing is intensively done so it is not wasted freely into the environment, second) toxicity of heavy metals decreased significantly with the application of chitosan adsorption method to heavy metals conducted in wider society. Bioadsorption method of heavy metals of ions Cadmium, Lead and Nickel using chitosan begins with insulation chitosan shell chitosan. The isolated chitosan was characterized. The performance of chitosan adsorption the three types of heavy metal tests was determined by chitosan interaction of each metal at varying pH interactions (pH 2-8). Interaction media conditions: 100 mL medium volume, total chitosan used 1 g, contact time 60 min, the heavy metal concentration of 200 μg/g cadmium ion test, Lead ions and Nickel respectively 100 μg/g. Determination of absorbance using Atomic Absorption Spectrophotometer. The measured value of the adsorbent is converted to the maximum chitosan adsorption concentration value. The adsorption capacity of metallic chitosan complex, maximum was achieved for metal Cd2+ at pH 2 of 198.2051 μg/g (99.05 %), metal Pb2+ at pH 4 of 59.3341 μg/g (59.33 %) and metals Ni2+ at pH 7 of 45.1334 μg/g (45.13 %). This result indicates that pH value of interaction media has an effect on chitosan adsorption to heavy metal test with Cd2+ ˃ ˃ Pb2+ ˃ Ni2+ sequence
