Heterogeneous Uptake of HNO3 on CaCO3: Determination of the Gas-Particle Reaction Probability as Function of Relative Humidity

Lead Institution

University of Iowa

Principal Investigator

Vicki Grassian

Project type

Large-Scale EMSL Research

The proposed work will provide an accurate measurement of the heterogeneous reaction probability for HNO3 on CaCO3 and its dependence on relative humidity. The value of &#947;HNO3 (uptake…
