Abstract AR
يكون العقار الرانتدين (N-[2-[[[5-[(dimethylamino) methyl] furan-2-yl] -N-methyl-2-nitroethene–1, 1– diamine hydrochlorid) (260nm) methyl]thio]ethyl] عند رقم هيدروجيني يتراوح بين 2-3 معقد آيوني ترابطي مع [AuBr4]-1 قابل للاستخلاص بمذيب 1-2 ثنائي كلورو إيثان تحت الظروف التجريبية الملائمة, حيث أمكن إقامة منحني معايرة يتصف بأرقام الاستحقاق التحليلية الآتية : مرحلة الخطبة الحركية LDR (1-80 مايكروغرام / مل)، RSD % (1.9)، حساسية ساندل (0.0360 مايكروغرام / سم2)، حدود الكشف (0.1 جزء في المليون), معامل الارتباط (r) يساوي 0.9988، الاسترداد في مئة 98.3 %, الخطأ النسبي بالمئة 1.68 %, نسبة الطور المائي إلى العضوي (5 : 4) الصيغة التركيبية (المولية) [AuBr4]-1 : RAN كنسبة 1 : 1.
Abstract EN
The drug ranitidine (N-[2-[[[5-[(dimethylamino) methyl] furan-2-yl] methyl] thio] ethyl] -N-methyl-2-nitroethene-1, 1-diamine hydrochlorid) forms (Xmax = 260nm) ion-pair association complex with [AuBr4]-1 at pH range 2-3 extractable with 1, 2-dichloroethane under the appropriate experimental conditions.
A calibration plot was set up from which some analytical parameters are derived.
These parameters include : linear dynamic range LDR (1-80 ^ g.
ml-1), RSD (1.
9 %), sandell sensitivity (0.0360), detection limit (0.
11ppm), Corr.
Coef (r) (0.
9988), recovery (98.
32 %), Erei (-1.
68 %) aqueous - to- organic phase ratio (5 : 4) and the mole-ratio method approved the [AuBr4]-1 : RAN as being 1 : 1 .
