in the present study, a new chemically modified carbon paste electrode (cpe) is constructed for rapid, accurate, simple, highly sensitive, and selective determination of mo (vi) using differential pulse voltammetry. the electrode was prepared using magnetic nickel zinc ferrite nanocomposite (ni0.5zn0.5fe2o4), as the modifier in cpe (ni0.5zn0.5fe2o4/cpe). mo (vi) was determined after preconcentr...

A simple, rapid and efficient method has been developed for the extraction, preconcentration and determination of cobalt (II) and nickel (II) ions in water samples by air-assisted liquid-liquid microextraction (AALLME) coupled with graphite furnace atomic absorption spectrometry (GFAAS). In the proposed method, much less volume of an organic solvent was used as the extraction solvent in the abs...
