the voltammetric characteristics of mo (vi) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-bap) and piperidinium perchlorate (pp) + piperidine (p) as  two different types supporting electrolytes, have been studied in chloroform. with the both supporting electrolytes a two electron irreversible process for the reduction  of mo (vi) oxinate was observed. p...

The d. c. and a. c. polarography and cyclic voltammetry were applied to the study of uranyl-salicylate and uranyl-phthalate complexes. The study was limited to the pH range <5, because insoluble uranyl-hydroxydes are formed above this pH value. Uranyl-salicylate and -phthalate are irreversibly reduced. The electrode process is preceded by the chemical reaction of the complex with protons. By th...

It was reported in the previous paper that thiamine and O-benzoylthiamine (OBT) reacted with iodine-oxidized egg albumin resulting in formation of protein thiamine mixed disulfide (1). The formation of protein-bound thiamine is de pendent on the pH of the reaction mixture and the amount of bound thiamine was much greater at pH 9.0 than at pH 7.3 possibly due to the difference of the amount of t...

The bilirubin-albumin solution containing 16 ing/100 ml of bilirubin and 2.5 g/100 ml of albumin was made according to Shinowara (i). The blank solution without bilirubin contained the same amount of albumin as the test solution. The Brdicka ilonfiltrate reaction was carried out as follows (2): 0.1 nil of test/blailk solution was added to 1.4 ml of 0.9% (w/v) NaC1 solution, and 1.5 ml of 0.25 N...
