    Voltammetric determination of rhodium by means of furan-oxime derivatives in industrial samples with considerable content of palladium
    (Publishing House of Lviv Polytechnic National University, 2011) Rydchuk, Petro; Gritchenko, Olena; Semenyshyn, Dariya; Tymoshuk, Oleksandr
    The selectivity of rhodium(III) voltammetric determination by means of furan-oxime derivatives has been investigated. The proposed methods have been approved on model solutions and during the determination of rhodium(III) in the presence of palladium(II) in complex industrial samples. Досліджено селективність вольтамперометричного визначення родію (ІІІ) за допомогою фуран-оксимових похідних. Проведено апробацію запропонованих методик на модельних розчинах та при визначенні родію (ІІІ) в присутності паладію (ІІ) у складних промислових об 'єктах.

    Voltammetric determination of iridium in alloys using xylenol orange
    (Publishing House of Lviv Polytechnic National University, 2011) Kharchuk, Roman; Tymoshuk, Oleksandr
    The possibility of iridium(IV) voltammetric determination using threephenylmethane dye (xylenol orange) has been investigated. The proposed technique has been tested using model solutions and in the process of iridium alloys analysis. Досліджено можливість вольтамперометричного визначення іридію (IV) за допомогою трифенілметанового барвника - ксиленолового оранжевого. Проведено апробацію запропонованої методики на модельних розчинах та при аналізі іридієвих сплавів.
