An air-assisted liquid-liquid extraction using a dual-valve sequential injection manifold (DV-SIA): Determination of copper

Abstrakt

This work introduces an approach to liquid-liquid extraction for the sequential injection technique by improving on a previously reported DV-SIA manifold. The method was applied to an assay of copper in pharmaceutical materials.
