15 صفحه اولdevelopment 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...
SPECTROPHOTOMETRIC AND GAS CHROMATOGRAPHIC METHODS FOR DETECTION AND ASSAY OF MUSTARD GAS
A colorimetric method for detection and assay of mustard gas in urine after addition of thymolphthalein is reported. The detection limit was 80 ng/ml of llrine. Mustard gas could also be detected in urine after extraction with gas chromatography using FID detector. The detection limit was 10 ng/ml. In addition, thiodiglycol, a metabolite of mustard gas, could be converted to mustard with ...
متن کاملGas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...
