Adsorption-Kinetic Non-Linear Wash-Out Model of Sulphur and Nitrogen Compounds from the Atmosphere
Abstract
Recently obtained measurement data indicates that sulphur and nitrogen wash-out is of essentially non-linear character relative to their air concentrations. A hypothesis of surface saturation of precipitation elements by pollutant in the course of their deposition is proposed and validated in the article. Moreover, observed non-linearities of wash-out process relative to both air concentrations and precipitation intensity are clearly qualitatively and quantitatively interpreted. At the same time the totality of occurred wash-out phenomena as well as the dependences of removal parameters on concentrations and precipitation intensities are explained. It is shown that theoretically obtained precipitation parameter values correspond to those measured. A physical-chemical explanation of surface saturation of precipitation elements is proposed. A non-linear mathematical wash-out model is being developed. The results correspond to observations.
