Description
В насто щее врем дл определени зольности промышленных растворов стрептомицина примен етс вес-овой метод.At present, the weight method is used to determine the ash content of industrial solutions of streptomycin.
Предлагаетс способ, в котором определение зольности промышленных растворов стрептомицина осуществл етс с помощью измерений, основанных на физико-химических свойствах анализируемых компонентов .A method is proposed in which the ash content of industrial solutions of streptomycin is determined using measurements based on the physicochemical properties of the analyzed components.
Применение описываемого способа обеспечивает более быстрое проведение анализа.The application of the described method provides a faster analysis.
Отличительна особенность способа состоит в том, что зольность определ ют путем измерени активности (концентрации), электропроводности и концентрации водородных ионов растЕ)Оров стрептомицина. При осу1цествлении способа используютс составленные экспериментальным путем графики:A distinctive feature of the method is that the ash content is determined by measuring the activity (concentration), electrical conductivity, and concentration of hydrogen ions above) Aurov streptomycin. In the implementation of the method, the experimentally constructed graphs are used:
а)график зависимости удельной электропроводности раствора от величины активности а А () при условии, если среда нейтральна и отсутствует зола (см. рис. 1);a) a plot of the specific electrical conductivity of the solution versus the activity of aA (), provided that the medium is neutral and there is no ash (see Fig. 1);
б)график зависимости удельной электропроводности раствора от величины золы f2 / (3) при различных рН при условии, если активность раствора равна нулю (см. рис. 2).b) a graph of the specific electrical conductivity of the solution on the value of the ash f2 / (3) at different pH, provided that the activity of the solution is zero (see Fig. 2).
Практика определени зольности растворов стрептомицина заключаетс в следующем:The practice of determining the ash content of streptomycin solutions is as follows:
а)измер етс активность А раствора на пол риметре, затем измер етс удельна электропроводность раствора кондуктометрическим методом, после чего с помощью ионометра замер етс рН раствора;a) the activity A of the solution is measured on a polarimeter, then the specific conductivity of the solution is measured by the conductometric method, after which the pH of the solution is measured using an ionometer;
б)определ етс удельна электропроводность fi. обусловленна только биологической концентрацией раствора, по известной активности Л, по графику ),b) the electrical conductivity fi is determined. due only to the biological concentration of the solution, according to the known activity of L, according to the schedule),
в) рассчитываетс разность Т2 (т - Ti ), обусловленна величиной золы при данном рН;c) the difference T2 (t - Ti) is calculated due to the amount of ash at a given pH;
г) определ етс по графику 2 /f5J зола в мг/мл, согласно рассчитанной Т2 и известного рН раствора.d) is determined according to schedule 2 / f5J ash in mg / ml, according to the calculated T2 and the known pH of the solution.
