(E)-3,4-Dihydroxybenzaldehyde 4-ethylthiosemicarbazone

4-17.2 Tronto (34-51)

Are social movements responsible for their unfi nished agendas? Feminist successes in opening the professions to women paved the way for the emergence of the upper middle-class two-career household. These households sometimes hire domestic servants to accomplish their child care work. If, as I shall argue, this practice is unjust and furthers social inequality, then it poses a moral problem for...

Simultaneolls spectrophotometric determination of molybdenum ( VI ) and titanium ( IV ) using 2 , 4 - dihydroxybenzaldehyde isonicotinoyl hydrazone

Determination of molybdenum(VI) by direct spectrophotometry and simultaneous determination of molybdenum(VI) and titanium(IV) are reported. Molybdenum(VI) gives a golden yellow colour with 2,4dihydroxybenzaldehyde isonicotinoyl hydrazone with a 1:2 metal-reagent stoichiometry at pH 1.5. The complex shows an absorption maximum at 445 nm with molar absorptivity and Sandell's sensitivity of 1.02x1...

Flow Injection Analysis of Mercury Using 4-(Dimethylamino) Benzaldehyde-4-Ethylthiosemicarbazone as the Ionophore of a Coated Wire Electrode

A flow injection analysis (FIA) incorporating a thiosemicarbazone-based coated wire electrode (CWE) was developed method for the determination of mercury(II). A 0.1 M KNO(3) carrier stream with pH between 1 and 5 and flow rate of 1 mL·min(-1) were used as optimum parameters. A linear plot within the concentration range of 5 × 10(-6)–0.1 M Hg(II), slope of 27.8 ± 1 mV per decade and correlation ...
