The presence of heavy metals in water has become a menace nowadays, when its harmful physiological and biological effects are considered. Challenges lies in the development of suitable system for mitigation of heavy metal concentration in water, thereby increasing its potable value. This paper focuses on the study of the general principles behind the application of biosorption to remove the heavy metals present in water. Copper and Chromium have been considered as examples. Prospective biosorbent and their characterisation, effects of factors such as pH, biosorbent dosage, equilibrium time and initial metal concentration have been dealt, giving adequate importance.
