A new solid contact copper selective electrode with a poly (vinyl chloride) (PVC) membrane consisting of o-xylylenebis(N,N-diisobutyldithiocarbamate) as ionophore has been prepared. The main novelties constructed ion concept are the enhanced robustness, cheapness, and fastness due to use contacts. exhibits rapid (< 10 seconds) near-Nernstian response Cu2+ activity from 10−1 10−6 mol/L at pH range 4.0–6.0. No serious interference common ions was found. characterizes by high potential...

The characterized on the basis elemental analysis, FT IR UV–VIS spectroscopy, electrochemistry (cyclic voltammetry) X–ray crystallography. consists molecular composition [Fe(nicotinamide)2(H2O)4]· [Fe(H2O)6]·(SO4)2·2H2O. crystallizes monoclinic space group P 21/c [a = 12.862(3), b 7.110(3), c 16.382(3) Å; β 95.79(2)°]. It has been proven that is coordinated to through...
A novel decavanadate salt, [V0.50(H2O)5]2[H2(V10O28)]·4(H2O), was obtained by the reaction of NH4VO3 with chinhydrone in an acidic medium. The title compound characterized solid and solution phases FT-IR, single crystal X-ray diffraction, voltammetry, UV-Vis., EPR NMR measurements. data are: H30O42V11, triclinic, Pī, a = 8.4906 (4) Å, b 10.4236 (5) c 11.2861 (6) α 68.490 (4)°, β 87.251 γ 67.145 V 851.11 (8) Å3, Z 1.

In this study, the voltammetric behaviour of interaction oxacillin sodium (OXA) and OXA-cysteine (RSH) was studied by square-wave voltammetry, cyclic voltammetry in Britton-Robinson (B-R) buffer (pH 7.0). OXA gave two peaks at -0.248 -1.224 V. For interaction, peak mercurous cysteine thiolate (Hg2(SR)2) selected. It found that currents corresponding to Hg2(SR)2 significantly decreased, while potential shifted more positive potentials upon addition OXA. The observed phenomena are due with RSH...
In the title compound, C15H11F3N2O4, N=C bond of central imine group adopts an E conformation. The dihedral angle between two benzene rings is 6.2 (2)°. There intra-molecular bifurcated O-H⋯(N,O) hydrogen with S(6) and S(9) ring motifs. crystal, mol-ecules are linked by C-H⋯O bonds into a helical chain along 31 screw axis parallel to c. -CF3 shows rotational disorder over sites, occupancies 0.39 (2) 0.61 (2).
The voltammetric behavior of niflumic acid (HNIF) in the presence and absence vanadium (V) was investigated using square-wave (SW) voltammetry at physiological pH. SW voltammogram HNIF exhibited only one cathodic peak -0.998 V. Due to complex formation between metavanadate (VO3-, abbreviated as MV) HNIF, a signal observed -1.228 According electrochemical results, stoichiometry V(V) found be 1:1. spectroscopic characterization synthesized solid powder V(V)-NIF also carried out.
In the title compound, C19H12Cl2N2O4, imine bond length of 1.257 (6) Å is typical a double bond. The dihedral angle between para-nitro benzene ring and central 12.06 (3)° that para-chloro 73.81 (2)°. An intra-molecular O-H⋯N hydrogen generates an S(6) motif. crystal, mol-ecules are linked together by two pairs C-H⋯O interactions (to same O atom acceptor), forming inversion dimers. A short Cl⋯Cl contact [3.232 (4) Å] observed.
The electrochemical characterization of sulfadiazine-cysteine (SD-CYS) adduct formation was performed in phosphate buffer (pH 7) on the basis voltammetric current and peak potential measurements. Due to association cysteine with sulfadiazine, reduction currents mercuric mercurous thiolates decreased their potentials simultaneously shifted less negative potentials. By using changes thiolate, it determined that sulfadiazine are associated a 1:1 stoichiometry conditional constant 1.99 ×104 M-1...
