5-AMINOTHIAZOLINETHIOCARBOXYLIC ACID-2-AMIDE USED AS ANALYTICAL REAGENT Ⅰ.DETECTION AND DETERMINATION OF PALLADIUM

T'IEN PING-SHIH and WANG K'UEI (Department of Chemistry, Peking Medical College)  
5-Aminothiazolinethiocarboxylic acid-2-amide may be used as a reagent forpalladium (II). The identification limit was found to be 0.003γ(1 : 1,000,000),when the detection was carried out on paper with neutral or weakly acidicsolutions. Among 34 cations studied, only Cu(II), Pt(IV), Fe(III), Ag(I),Au(III) and Hg(II) interfered in neutral or weakly acidie solution. If spotchromatographic method or paper chromatographic method were used, Pd(II)may be detected in the presence of considerable amount of those interferingcations. The acidity influenced the colour intensity and precipitation. At pH1, abrownish red precipitate was formed, which was redissolved as pH reached3--4 forming an orange red solution. It changed to orange yellow and becameturbid at pH 5. At pH 6--8, a turmeric yellow precipitate was formed. By means of continuous variation method, the ratio of reagent to palladiumwas found to be 3 : 2 at pH 4. The colour intensities obeyed Beer-Lambert's law in the concentrationinterval 0.3--0.8 mg Pd/10 ml solution. Palladium may be precipitated in ammoniacal solution with this reagent.The precipitate decomposed on drying at higher temperature, but it may beignited to metallic palladium and weighed as such. The results agreed wellwith those obtained by means of dimethylglyoxime.
