A study on the adsorption characteristics of filtering materials

A convenient procedure of preparing chemical impregnants of TEDA (Triethylenediamine) and its alkyl derivatives has been searched, and dimethyl iodides of TEDA and TEDA derivatives were prepared in a good yield. These iodides were converted to their diethoxides and thermal decomposition of these ethoxides are being investigated to obtain the corresponding TEDA and TEDA derivatives. Parameters on the impregnation of a base carbon with TEDA + Dimethyl iodide of TEDA or TEDA derivatives were searched, and basic data were obtained. Active carbon samples prepared in this project were examined for their physical properties and performances by means of ASTM D-Series Standards and chemical compositions and deterioration patterns were also checked on basis of analytical methods developed by this laboratory. Experimental results obtained in this research were reviewed and possible measures to implement these research data in this country were also studied. (Author)
