✦ Synopsis

Ahstraet-The absorption of NO m aqueous mixed solutions of NaClO* and NaOH was carned out usmg a sernl-batch stured vessel with a plam gas-liquid interface at 25'C The rate of absorption was discussed on the basis of chemical absorption theory under the fast-reaction regnne The overall reaction involved was presented by 4N0 + 3NaCI0, + 4NaOH = 4NaN0, + 3NaCI + 2H,O and was found to be second-order with respect to NO and first-order with respect to NaCIOz m the range of NaClq concentration greater than 0 8 molar The reaction rate constants evaluated were exponentmlly decreased with the NaOH concentration and correlated by k = k,, exp ( -3 73C,,)
