"Continuous-flow Analysis. Determination Of Osmium Using A Catalytic Reaction Of P-phenylenediamine With Hydrogen Peroxide"
Vestn. Mosk. Univ. Khim. 1992 Volume 33, Issue 5 Pages 472-475
Rodionova, T.V.;Beklemishev, M.K.;Chigvintseva, E.V.;Zolotov, Y.A.

Abstract: An automatic continuous-flow system with flow segment is used for the determination of Os, based on its catalytic effect on the reaction of p-phenylenediamine and hydrogen peroxide. The reaction is performed in pH 7.0 solution The concentrations. of p-phenylenediamine and hydrogen peroxide should be higher than 5.0 x 10^-3 and 1M, respectively. The detection limit is 1 x 10^-5 µg/mL. The relative standard deviation is 0.06 at the low determination concentration. range. The productivity is 48 samples per h.

"Continuous-flow Analysis. 1. Determination Of Chromium(VI) By Using Diphenylcarbazide"
Vestn. Mosk. Univ. Khim. 1990 Volume 31, Issue 6 Pages 559-561
Beklemishev, M. K.; Rodionova, T. V. (SFS)

Abstract: The parameters of continuous-flow and flow-injection anal. were compared. The performance of the continuous-flow technique is quite competitive (sr = 0.003-0.05 for 0.005-2.0 mg/mL; throughput up to 150 samples/h). (SFS)
