Single-walled carbon nanotubes (SWNT) are proposed as chiral selectors for separation of carvedilol stereoisomers beginning since its racemic mixture. The novel developed FIA-methodology employs a microcolumn (mC) packed with a few milligrams of SWNT

Two simple and sensitive surfactant-mediated spectrofluorimetric methods for the determination of sildenafil are proposed in this paper. These methods are based on the interaction of sildenafil with normal micelles of HTAB (hexadecyltrimethylammonium

A new, simple and precise indirect method for the determination of terazosin through x-ray fluorescence (XRF) is proposed. The method is based on the precipitation of an ion-associate complex formed between terazosin and [Zn(SCN)4]2- and the formatio
