  Benign Graphite-Chitosan Blended Bio-Composite for Sorption of Toxic Nitrate from Water
  Author(s): Rajendra S Dongre Rajendra S Dongre
  
  Assorted nitrogen/phosphorous fertilizer, pesticide and nutrient usage is intensified for crop developments in agricultures in past few decades. Unused nitrate get percolated from sandy/textured soil during rains. Nitrate poisoning imparts methemo-globinemia/blue-baby syndrome besides eutrophication as detrimental to human and ecosystem both. Nitrate contamination is mitigated by water de-nitrification being achieved via various treatments viz; ion exchange resins, Reverse Osmosis (RO) and distillation. Ion exchange operates at household level, softener filters calcium/magnesium laden water passed through resins which exchanges chloride for nitrate. Regeneration of resin is costly issue, so ion exchange is not preferred. RO is helpful, but owns some disadvantages viz; expensive, high energy inputs, inefficient, squander more water and operates at low pressure. Distillation being slow and.. View More»
