摘要：The urbanization rate in India is very fast. It has increased from 10.84 to 28.5% upto 2001. Unregulated growth of urban area causes many problems. Due to increase in population, urbanization and industrialization, many air pollutants are entering into atmosphere and causing diseases. One of the most toxic air pollutant is NO₂. The present study deals with the adsorption of aqueous solution of NO₂ by mango bark dust. The adsorption experiments were conducted with respect to contact time, mango bark dust dosages, concentration and temperature. It was found that percentage removal increased with increase in contact time and with increase in adsorbent dosage. It follows first order kinetics. The amount of NO₂ gas adsorbed is more at lower concentration than at higher concentrations
