In the present study it has been found that algae have immense capacity to absorb metals, and there is considerable potential for using them to treat wastewater.Concentration of metal and biomass of algae, pH, temperature, biochemical activities of the organism affect the rate of metal absorption. Algae can effectively remove metals from water bodies. In the case of test spices, Diatoms can be used for removal of Arsenic from aquatic biota. The present investigation was under taken to study the removal of Arsenic from the metal treated medium in vitro. Arsenic is a carcinogenic and highly toxic heavy metal existed in two valiancy state such as As (V) and As (III). The toxicity of metal can be reduced in alkaline condition. So the sea water containing medium were used for the present study. The parameters of productivity, photosynthesis rate, respiration, pigmentation, end product of photosynthesis bioactive phenol and proline were studied in different concentration of As (III) and As (V). The maximum removal of the metal from the aquous medium was observed at the exponential growth phase and also increase in the amount of proline and phenol in the test species under stress condition. So algae are used for biosorption of Arsenic from the aquatic biota.
