A dsorptio n Isotherm Study of Loratadine on M ulti -Walle d Carbon Nanotube

Carbon nanotubes (CNT)discovery by Iij ima in ۱۹۹۱[۱]. Carbon nanotubes ( CNTs) are hollow cylinders of graph ite carbon a toms .Thes e tubes are on the nano scale (۱۰-۹ m). Carbon nano-tubes are a new fo rm of carbo n with unique electrical and mechanical properties .They can be consid ered as the result of fol ding graphite layers into carbon cylinders .The se cylinder s may be co mposed of s ingle shell single wall Carbon nan o-tubes (S WCNTs), or of several shells multi-wall Carbon nanotube s (MWCNTs). Due to the variety of extraordinary properties exhibited by CNTs , a large n umber of possible applic ations have been proposed. [۲] Loratadine is a white to off- white powder not soluble in water. It has a molecular weight of ۳۸۲.۸۹ , and empirical formula of C۲۲H۲ ۳CIN۲O۲. Loratadine is a second-generati on H۱ hist amine antago nist drug used to treat allergies. Structur ally, it is closely related to tri cyclic antidepressants, s uch as imipramine . [۳]
