A Method for the Quantitative Determination of Phenols*
In studying the anthelmintic properties of certain alkylphenols it became necessary to determine the degree of absorption and excretion of these substances. Although satisfactory quantitative tests for many types of phenols are known and have been reviewed by Gibbs (l), an exhaustive search of the literature failed to reveal any method that was applicable to those p-substituted phenols which ar...

متن کاملA Quantitative Method of Determining Urinary Phenols.
‘IT0STUDY PROTEIN METABOLISM with special reference to tyrosine as well as to study the deranged metabolism of aromatic compounds in phenylketonuria and similar disorders, quantitative determination of urinary phenols is desirable. Volterra (1) measured three phenolic fractions in the urine by distillation. Phenols have been measured quantitatively after ethyl acetate extraction by Bray and Tho...

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 ...
15 صفحه اولAn Ether Extraction Method for the Determination of Urine Phenols
Experiments previously reported from this laboratory (1) have shown that less than 1 per cent of the “total diazo” value of the blood is actually made up of phenols, the reactive substances being almost exclusively etherinsoluble and presumably nitrogenous in nature1 (2). In the present work, an attempt was made to develop more specific methods for the determination of the various groups of uri...
