چکیده
den sind, um andere, offenbar auch leichter wieder abtrennbare Proteine zu binden. C H A R G A F F und sein Arbeitskreis2 '12 haben bei der Fraktionierung von DN-Histonen mit NaCl-Lösung ansteigender Konzentration DNS-Fraktionen von unterschiedlicher Zusammensetzung und unterschiedlichem Bindungsvermögen erhalten. Die von uns gewonnenen Beobachtungen führen zu dem gleichen Ergebnis. Herrn Direktor G . A. K A U S C H E danke ich für sein förderndes Interesse an dieser Arbeit, Frl. S.

Kinetic spectrophotometric determination of trace amounts of nitrite ion using potassium bromate-murexide mixture in acidic media
A new, simple, rapid, and cheap method for determination of trace amounts of nitrite ion is reported.Determination is based on reduction of bromate ion by nitrite ion, in the presence of murexide inacidic media. During reaction of bromate ion with nitrite ion, the reaction mixture is decolorized.The absorbance changes is then monitored spectrophotometricaly at 520 nm, at 25 °C. Dynamicrange of ...
متن کاملTHE KINETICS OF HYDROLYSIS OF TRANS-DIFLUOROTETRAMMINECHROMIUM (111) ION IN VARIOUS CONCENTRATED ACID SOLUTIONS
The rate of hydrolysis of trans -[Cr(NH ) F ] was obtained as a function of acid concentsation in perchloric, sulfuric and nitric acid at 3Q°C. The results have been analyzed by the treatment of Bunnett and Olsen. Values of the parameter ?in Olsen equation are consistent with the participation of water as a proton-wansfer agent in the rate-determining step. The Arrhenius plot for perchlori...
متن کاملKinetic and thermodynamic studies of the removal of murexide from aqueous solutions on to activated carbon
The objective of this study was to assess the adsorption potential of activated carbon (AC) asan adsorbent for the removal of Murexide (Mu) from aqueous solutions. The influence of variablesparameters including pH, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon Mu removal was studied. Following optimization of variables, the relation between concentrations ofdye re...
متن کاملStudies on Transition Metal Murexide Complexes
Murexide, a reddish purple compound has the structure shown in Fig. 1. It has received much interest because of its application in chemical analysis and spectrophotometric fields [1, 2]. It is considered as the ammonium salt of purpuric acid and named as ammonium 2,6-dioxo-5-(2,4,6-trioxo-tetrahydro-pyrimidine-5-ylidene amino)-1,2,3,6-tetrahydro-pyrimidine-4-olate. It serves as a metal ion indi...
متن کاملKinetics and mechanism of the reaction of lysine with permanganate ion at different ionic strengths and temperatures
The kinetics of Mn(VII) oxidation of lysine in moderately sulfuric acid solutions was studiedspectrophotometrically in the presence and absence of Mn(II) as catalyst. The reaction was arrangedto be under pseudo first-order condition with respect to Mn(VII). The results showed that the pseudofirst-order rate constant increases with increasing [H2SO4], [(Mn)II], and [lysine]. The dependence ofthe...
