development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Application of Factorial Design for Optimization of Spectrophotometric Determination of Cefdinir Using MBTH
The target of the present study is to use experimental design in screening and optimizing experimental variables to develop a spectrophotometric method for determination of Cefdinir (CFN) antibiotic. The proposed method is based on the oxidative coupling reaction of CFN with 3methylbenzothiazolinone-2hydrazone (MBTH) in presence of FeCl3 in acidic medium forming a green colored chromogen measur...
متن کاملSpectrophotometric determination of Cilastazol using p-dimethylaminobenzaldehyde
A simple accurate and reproducible spectrophotometric method was established for the estimation of Cilastazol based on the formation of condensation product. The method is based on the formation of yellow colored chromogen, when the drug reacts with p-Dimethylaminobenzaldehyde (PDAB). The colored species has an absorption maximum at 425 nm and obeys Beer's law in the concentration range of 6-10...
متن کاملSpectrophotometric Determination of Hydralazine Using p-Dimethylaminobenzaldehyde
A new spectrophotometric method for the assay of hydralazine hydrochloride in bulk and dosage forms has been developed. The procedure is based on a condensation reaction between alcoholic solution of hydralazine and acidic solution of pdimethylaminobenzaldehyde to generate an instant greenish-yellow coloured product. The hydrazone formed absorbed visible light strongly and optimal detector resp...
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
