Summary According to the measurements performed the redox potential of thionoline changes at the temperature of 40° C in the pH-range of 0,66 to 8,11 from 0,542 V to 0,087 V (SCE). Thionoline can be used for the selective detection of BrO3
– in the presence of ClO3
–, IO3
– and the free halogens (sensitivity pD=5,4), as well as for the selective detection of Sn2+ in the presence of Cr2+, Ti3+, V2+ and Fe2+ (pD=4,6). Sn2+, Ti3+ and Cr2+ can be titrated potentiometrically with thionoline solution in the presence of Co2+, Ni2+, Mn2+, Al3+ and Zn2+. V2+ and Fe2+ interfere with this reaction. Sb3+ interferes with the determination of Sn2+ and Cr2+.Chlorine and bromine water in ethanolic solution convert the thionoline easily and quantitatively in tetrahalogenated products. The halogenation can be watched potentiometrically. 相似文献
