Abstract

Adsorpiion ofNOj m packed colvmııs 'was investigaîed by îising beıge sepioliîe

and regenerated belge sepioliSe as adsorbents. For ihis purpose, NO: was produced by reacting

copper with nitı'ic acid The prochiced gas was mixed \viîh air and îhe mixture . was sent to a

packed colvmn.. Remainmg NO: wthın fhe gas mıxfure leavmg îhe column uiîadsorbed on

packfng, \vc{s furthef absorbed by passmg it fhroiigh a series ofgas washmg boffles fılîeü \vifh the

soiufson ofNaOH. The amount of N0^ in fhe absorpUon solution \vas determined by photometrıc

method. The resulîs \vere phtted.
