It is important for mankind to diminish carbon dioxide in the atmosphere. We attempt to utilize ultrasound for reducing C02. As the result, the amount of C02 decreased to about half for one hour sonication. Carbon monooxide and hydrogen were evolved during sonication. The behavior of CO was related to that of C02. On the other hand, H2 behaved independently. Temperature dependence of the decreasing rate for C02 was observed. The decreasing rate was down with increasing temperature in the range of 5-45℃. Thus, the efficiency of sonication was down in the high temperature region. The effect of dissolved (or satulated) gas in the solution on sonolysis was also observed. The decreasing rate for C02 followed the order Ar>He>H2>N2.
