Separation of some biogenic amines via RP-HPLC using mixed micellar mobile phase was investigated. The compounds were derivatized before hand by dansyl chloride as a chromophoric reagent. Appropriate conditions for separation, were determined by studying factors such as temperature, type and percentage of organic modifier, concentration of surfactants (SDS and Brij-35) and the pH of the mob...

This paper describes a method for solving the permutation problem in blind source separation (BSS) by frequencydomain independent component analysis (FD-ICA). FDICA is a well-known method for BSS of convolutive mixtures. However, FD-ICA has a source permutation problem, where estimated source components can become swapped at different frequencies. Many researchers have suggested methods to solv...

the aim of this work was to develop a selective cloud point extraction method for the separation and preconcentration of copper(ii) prior to spectrophotometric determination. for this purpose dithizone was used as a complexing agent and the experimental solution was acidified with sulfuric acid. triton x-114 was used as a surfactant and after phase separation, based on the cloud point of the mi...
