The main purpose of this paper is to introduce a concept of semi separation axioms in L-fuzzifying bitopological spaces (here L is a complete residuated lattice some times used double negation law) and discuss some of their basic properties and the s

The polarographic behavior of metal ions in perchlorate media containing gallic acid is described. Tungsten(VI) forms a complex with gallic acid which yields a single wave in these media, useful in the polarographic determination of tungsten. Evidenc

The stability constants of the complexes between the trivalent lanthanide series of cations and series of azo-B-diketone ligands are reported. The measurements were conducted at 30°C and zero ionic strength (free KN03), in 100% methanol. The relatio

Uranyl ion reduction was studied in acetate buffer-resorcinol medium. Two waves were obtained for all pH. Resorcinol can be used as a maximum suppressor. Complexation of uranium with resorcinol was accompanied by a decrease in diffusion current and s

The results of pH-metric titration have been used to determine the acid dissociation constants of 2-carboxy-pheylhydrazo-ethylacetoacetate abbrivated (2-CPHEA) and the overall stability constant (log β=KML, KML2) of twelve rare earth element complex
