Beschreibungen/Notizen

• A rapid spectrophotometric method has been developed for microdetermination of Te(IV) after co-precipitation of its morpholine-4-carbodithioate complex on microcrystalline naphthalene and subsequent dissolution in chloroform. The molar absorptivity at 415 nm is 9.18 × 10 3 l.mole −1.cm −1. Beer's law is obeyed over the range 5–75 μg of Te(IV); 25.0 μg of Te(IV) in 10.0 ml of final solution gives a mean absorbance of 0.180 with a relative standard deviation of 0.55%. The method has been tested for determination of tellurium in some alloys and synthetic mixtures.
