In tbe present paper, the adsorption heats of CO on copper (powder) have been determined by impulsive method with Rigaku TG-DTA-DSC thermal analyzer, Ar as the carrier gas. The sample Cu is prepared by precipitation of copper nitrate. The weight of adsorbed CO is designated by TG curves and heat by peak area of DSC. The instrument constant is determined by means of standard substances, such as In Sn and Pb.
Relationship between instrument constant K and temperature T can be represented as following equation:
K=9.464-23.33×10~(-3) T+25.74×10~(-6) T~2
It is found that the temperature has influence on the adsorption heat of CO. The...
