تشکیل کمپلکس های tarبا یون های لانتانیم, ایتریم و توریم در دمای 25 درجه، قدرت یونی ثابت 0.1 مولار و در ph ثابت در مخلوط حلال های اتانول – آب و استونیتریل – آب با استفاده از روش های اسپکتروفوتومتری مورد بحث و بررسی قرار گرفت. داده های اسپکتروفوتومتری با استفاده از نرم افزار squad پردازش شدند تا ثابت های تشکیل کمپلکس اندیکاتور – فلز را محاسبه کند. نتایج نشان می دهد که درصد حلال آلی در مخلوط حلال ...
15 صفحه اولNitrite Determination by the Differential Pulse Polarographic Method
In this work; the optimum conditions of the differential pulse polarographic method conditions of the polarographic reduction of diphenylnitrosoamine which was occured by nitrite ion and diphenylamine in perchloric acidic medium and thiocyanate ion as catalyst, were determined. At these polarogram conditions, nitrite ion gave a maximum diffusion current at -0.56 V. The differential pulse polaro...
متن کاملRapid determination of phenolic compounds in water samples by alternating-current oscillopolarographic titration.
A rapid, simple and sensitive method was demonstrated for the determination of phenolic compounds in water samples by alternating-current oscillopolarographic titration. With the presence of sulfuric acid, phenol could be transferred into a nitroso-compound by reacting with NaNO2. The titration end-point was obtained by the formation of a sharp cut in the oscillopolarographic with infinitesimal...
متن کاملDetermination of glyphosate in water samples by alternating-current oscillopolarographic titration.
This paper describes a novel, simple and sensitive method for the determination of glyphosate in water samples by alternating-current oscillopolarographic titration. Under an acidic condition, glyphosate can be transferred into a nitrosocompound by reacting with NaNO2. The titration end-point was obtained by the formation of a sharp cut in the oscillopolarographic with infinitesimal NaNO2 on do...
متن کاملA Direct Current Polarographic Method for the Determination of Chlorpheniramine Maleate in Pharmaceutical Preparations
A direct polarographic method for the determination of chlorpheniramine maleate in pharmaceutical preparations had been developed. The method was based on the reduction of chlorpheniramine maleate in an acidic medium (pH 1.2-4.0). The effect of pH on the polarographic wave was investigated by recording d.c. polarograms in various supporting electrolytes. The calibration graphs were rectilinear ...
