A column coated with a polymer inclusion film (PIF) containing Aliquat 336 as carrier cast on
glass beads packed in a glass tube is described for the separation, preconcentration, and …

This paper reports the first use of a polymer inclusion membrane (PIM) for on-line separation
in flow injection analysis (FIA) involving simultaneous extraction and back-extraction. The …

A flow-injection method has been developed for the spectrophotometric determination of
cobalt in zinc electrolyte using 2-(5-bromo-2-pyridylazo)-5-(N-propyl-N-sulphopropylamino) …

Cyclic methods of analysis can lead to many advantages, such as low consumption of
reagents, minimization of waste, high sample throughput, simple equipment, extended …

Flow-injection solid-phase spectrophotometry is applied for sequential determination of
nickel and zinc, exploiting their different sorption rates on 1-(2-thiazolylazo)-2-naphthol …

It is currently recognized that the content of trace elements greatly affects the properties of
steel products. To characterize the quality of the products, therefore, concentrations of the …

A flow injection spectrophotometric method for the simultaneous determination of copper (II)
and zinc (II) in mixtures was developed, utilizing metal–zincon complex formation and kinetic …

An automated flow injection method for the determination of zinc, based on the zincon
method with differential demasking of the cyanide metal complexes with cyclohexanone, is …

A novel strategy for utilization of solid reagents in flow analysis is proposed. Establishment
of diffuse and reproducible geometry enables the solid particles to be maintained in constant …

The use of ICP/AES for the determination of zinc, in low concentration levels, in matrices
containing high levels of copper is difficult because copper interferes in the zinc main …
