WebThe dry deposition of sulphur dioxide to la'nd and water surfaces 247 explained if the deposition rate for sulphur dioxide was similar to that measured for iodine. Although dry deposition appeared to be the major removal mechanism, at least over Britain, it received little further attention before the present decade. WebThe rate-limiting step is considered to be an electrochemical surface reaction, a conclusion which is substantiated by electrode half cell potential measurements. Using the Butler-Volmer equation, a theoretical analysis of the electrochemical reaction resulted in the following rate equation: dn MnO 2 dt=κ ∗K 0.5 aA c[ SO 2] 0.5 total [ H +] [[ H +]+K a 0.5 …
