Screening of some transition metal ions and quantitative determination of copper, cadmium and zinc by solid phase derivative spectrophotometry
(2004)
A simple solid phase spectrophotometric method for both screening of eight transition metal ions plus lead and quantitative determination of copper, cadmium and zinc is described. The method is based on the preparation of ...

Determination of tetramethylthiuram disulfide (thiram) for residual analysis in food using spectrophotometry coupled with a solid-phase reactor (SPR) in a flow system
(Taylor & Francis Ltd, 2014-01-01)
An analytical method was developed for quantification of the fungicide thiram (tetramethylthiuram disulfide), based on its capacity to complex Cu2+ ions. A solid-phase reactor (SPR) was coupled in a flow system containing ...
Rotating disk sorptive extraction of cu-bisdiethyldithiocarbamate complex from water and its application to solid phase spectrophotometric quantification
(Japan Society for Analytical Chemistry, 2014)
This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible ...
