Simple microdetermination of uric acid.
In 1947 Kalckar introduced a comprehensive differential spectrophotometric system for the analysis of purines, including uric acid (1). Praetorius and his associate Poulsen employed this procedure and have published detailed directions for a practical uric acid method (2, 3). During the past 4 years, over 2000 routine uric acid determinations on blood and urine have been performed in this labor...
متن کاملThe Recovery of Uraniumfrom Phosphoric Acid
Commercialization of three processes (OPPA, DBPA-TOPO and OPAP) has shown that the DEPA-TOPO process offers the best technology available today for the recovery of uranium from wet-process phosphoric acid. Uranium recovery plants using this process have been successfully operated in the United States, Belgium, Canada and Taiwan. Operating experience from these plants has led to a significant re...
متن کاملContinuous Melt Suspension Crystallization of Phosphoric Acid
A continuous melt suspension crystallization process has been presented for the purification of the phosphoric acid in this study, which is performed in the cascade of a mixed suspension mixed product removal (MSMPR) crystallizer and a gravity wash column for the subsequent solid-liquid separation. Dynamic behavior in the crystallizer and role of reflux ratio on the purification efficiency of c...
متن کاملPhytin and Phosphoric Acid Esters of Inosite
In continuation of the physiological investigation concerning the metabolism of the organic-phosphorus compound known as phytin, which has been and is being carried out at this institution by Dr. Jordan, a closer study of the chemical properties of this substance, phytin, became necessary. Much work has already been done and reported on this subject by various investigators. Definite informatio...
متن کامل[A modified method for the microdetermination of citric acid].
An investigation of the different steps in the method of Weil-Malherbe & Bone (1949), as modified by Taylor (1953), has led to an altered procedure for citric acid determination, with increased sensitivity and accuracy. The main modifications involved are the use of (i) a higher concentration of sulphuric acid during the formation of pentabromoacetone, and (ii) a thiourea-borax-sodium sulphide ...
