PREPARATION AND CHARACTERIZATION OF BONDED-PHASES OF CALIXARENE-SULFONYL-CARBOXAMIDES IN PARTIAL-CONE CONFORMATION FOR DETERMINATION OF SALBUTAMOL IN LIVESTOCK BY NANO-MEDIATED BONDED-PHASES: NANO-BASKETS OF CALIXARENE IN PARTIAL-CONE CONFORMATION. J. Chil. Chem. Soc. [online]. 2012, vol.57, n.2, pp. 1150-1154. ISSN 0717-9707. http://dx.doi.org/10.4067/S0717-97072012000200020.
A new sensitive method for determination of salbutamol, as a nutrient repartitioning agent, in livestock is presented to protect the consumers. Eight nano-baskets of p-tert-calixarene bearing di-[N-(X)sulfonyl carboxamide] and di-(1-propoxy) in partial-cone conformation were synthesized and were used to prepare bended phases of HPLC-UV. The new synthesized bonded-phases were characterized and optimized, the bonding interactions of solute and stationary phases were examined and the main interactions were reported. The results revealed that for the best bonded-phase, the LOD and LOQ were 0.02 and 0.06 μg/mL, respectively.
