The behavior of the gas-liquid contact was studied in a bubble column packed with spiral wires to increase the contact effects. Carbon dioxide-air mixture was passed into potassium carbonate-bicarbonate buffer solution. Under the optimum condition （D=6 ㎜, P/D=2） of the spiral wire packing, the interfacial area for the packed column became approximately two times of that for the column without spiral wires and the liquid-side mass transfer coefficient for the packed column was approximately four times of that for the unpacked column. The axial mixing coefficient of the packed system decreased to one half of the unpacked system.
