Several SPE sorbents were investigated for the extraction of a group of chemically diverse isothiocyanates (ITCs). They included bonded silica, carbon‐based, and polymer‐based sorbents with various functional groups. Results showed large differences in the ability of these sorbents to simultaneously extract ITCs from standard solutions.

Simultaneous spectrofluorimetric determination of the rare earths with calcein
Talanta, 1999The reactivity of the fluorescent reagent calcein with the trivalent cations of the rare earths has been spectrofluorimetrically studied in aqueous solution. Optimum excitation and emission wavelengths were 492-497 and 519-522 nm, respectively. Optimum pH was in the range 6.0-9.2. The stoichiometry of the complexes was 1:1.

Simultaneous determination of arsenic and phosphorus
Microchimica Acta, 1965A simple, rapid, accurate and reliable method for the simultaneous determination of arsenic and phosphorus in the presence of each other is reported. The method involves the selective solvent extraction of phosphomolybdic acid by isobutyl acetate, the direct reduction of the phosphomolybdic acid in the solvent phase by 1-amino-2-naphthol-4-sulphonic ...
