Simultaneous kinetic determination of beryllium and aluminium by spectrophotometric H-point standard addition method.
The H-point standard addition method (HPSAM), based on spectrophotometric measurements for simultaneous determination of beryllium and aluminium, is described. This method is based on the difference between their rates of reactions with Chrome Azurol S (CAS) in cetyltrimethylammonium bromide (CTAB) micellar media. The results showed that beryllium and aluminium could be determined simultaneousl...
متن کاملSimultaneous kinetic spectrophotometric determination of citric and ascorbic acid by H-point standard addition method
The H-point standard addition method was applied to kinetic data for simultaneous determination of citric and ascorbic acid or selective determination of ascorbic acid in presence of citric acid. The method is based on the difference in the rate of reaction of citric and ascorbic acid with copper(II)-ammonia complex. The linear dynamic ranges for the two analytes of citric and ascorbic acid are...
متن کاملSimultaneous Spectrophotometric Determination of Vanadium(V) and Iron(III) in Micellar Medium by H-Point Standard Addition Method
H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...
متن کاملApplication of H-Point Standard Addition Method for Simultaneous Spectrophotometric Determination of Hydrochlorothiazide and Propranolol
A aplicação do método de adição padrão no ponto H para solucionar os espectros sobrepostos de hidroclorotiazida e propranolol foi avaliado. Os resultados mostram que o método HPSAM pode ser aplicado para a determinação simultânea dos compostos, em meio aquoso. Os resultados da aplicação do HPSAM mostraram que as duas drogas podem ser determinadas simultaneamente, numa razão de concentração hidr...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
