Adsorptio n Isotherm Study o f Ketotife n on Multi -Walle d Carbon Nanotube

Carbon nanotubes (CNT) discovery by Iijima 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 single (MWC NTs).Due to the variety of extraord inary properties exhibited by CNTs , a large n umber of possible appli cations have been proposed. [۲] Ketotifen is a second-gener ation H۱-antihistamine and mast cell stabilizer. It is most commonly s old in as a salt of fumaric acid, ket otifen fumarate, and is available in two forms. In its opht halmic form, it is used to treat allerg ic conjunctivitis, or the itchy red ey es caused by allergies. In its oral form, it is used to prevent asthma attacks. Side effects inclu de drowsiness, weight gain, dry m outh, irritability, and in creased nose bleeds. [۳]
