Biosorption for Removal of Nitratesand Phosphates: A Review

Abstract: Although notable progress is being made by researchers in the development of tenable and advanced water treatment technologies, stillhuge population and increasing water demand present challenges for water field researchers.Among multitude of pollutants, removal of nitrates and phosphates,is one of the most threatening issues of global water contamination. For this, biosorption has been used and analysed extensively. In this review, all different sorbent materials, particularly for nitrates and phosphates, are hereby listed and discussed. A brief proposal has also been made about the development of combination of sorbent materials, for both nitrates and phosphates, so that after usage, these materials can be recycled and reused as a source of nitrates and phosphates for various useful purposes. Keywords- Biosorption, Biosorbent, Nitrates, Phosphates.
