Multivariate optimization of supported liquid membrane extraction of biogenic amines from wine samples prior to liquid chromatography determination as dabsyl derivatives

“…The extraction efficiency in SLM is defined as the ratio between the number of moles collected in the acceptor and the number of moles of analyte input into the system during the extraction time [18]. SLM extraction has been applied to a variety of analytes [17], such as drugs [19], metal ions [20], triazines [21], and amines [22,23], present in environmental and biological samples. In relation to the extraction of amines, there are several approaches for direct extraction of aliphatic amines, using solvents as di-n-hexyl ether and n-undecane [22 -24].…”
