In rural India, nitrite-contaminated water is common. Economical and safe water treatment is needed to eliminate nitrite. Nitrite levels in drinking water are restricted because excess might induce methemoglobinemia (blue-baby syndrome). The world has 3% clean water. Nitrite-containing pollutants from human and industrial activities pollute water resources and jeopardize human and ecological health. Chemical precipitation and membrane filtration are expensive when treating large volumes of water, ineffective at low metal concentrations, and produce large amounts of toxic sludge and other byproducts that must be disposed of properly. Bio-sorption is a greener wastewater treatment technology. These cheaper, more accessible, and reusable methods have benefits over conventional ones. This study tests biosorbents such neem leaf, custard apple leaf, guava leaf, mango tree leaf, orange peel, and banana peel for nitrite removal from contaminated water and 100% removal was achieved. The effects of contact length, agitation speed, adsorbent dose, pH, and temperature are also examined. Before usage, biomass can be physically and chemically changed. Regenerating and reprocessing biosorbent after heavy metal removal makes the procedure cost-effective.
