In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect(More)
The resolution of clenbuterol hydrochloride enantiomers was achieved by thin-layer chromatography on silica gel GF254 plates impregnated w ith beta-cyclodextrin. The effect of stereoselective auxiliary (acetonitrile and alcohol) was investigated. Resolution of clenbuterol hydrochloride enantiomers could be attained by using alcohols of butanol, 2-butanol or(More)

A capillary GC method for the simultaneous determination of cannabidiol (CBD), tetrahydrocannabinol (THC), and cannabinol (CBN) in cannabis is described. The major components in cannabis were extracted with chloroform. After being concentrated by evaporation, the residue was dissolved in methanol. The resulting solution was used for analysis. The conditions(More)
