Spectroscopic Studies of Triton X-114 and Quercetin/Rutin Solutions
Flavonoids belong to a large group of natural polyphenol compounds and have a broad spectrum of pharmacological activities. Many natural flavonoids are characterized by extremely low solubility in aqueous media and body fluids. To improve the solubility of drugs, various methods were developed and are used in pharmaceutics: solubilization, preparation of solid disperse systems with soluble and ...
متن کاملRemoval of endotoxin from protein solutions by phase separation using Triton X-114.
Endotoxin contamination of protein solutions was reduced by a phase separation technique using the detergent, Triton X-114. Protein solutions containing endotoxin were treated with Triton X-114 on ice. The solution was then warmed to 37 degrees C, whereupon two phases formed. The Triton X-114 phase, containing the endotoxin, was precipitated by centrifugation. The first cycle of phase separatio...
متن کاملSpectrophotometric Determination of Acidity Constants of Thiamine in Water, Water-Triton X-100 Micellar Media Solutions
In this work the acidity constants of Thiamine in water and water-Triton X-100 micelle media solutions, at 25 °C, have been determined spectrophotometrically. To evaluate the pH- absorbance data, a resolution based on the combination of soft-and hard-modeling is applied. The acidity constants of all related equilibria are estimated using the whole spectral fitting of the collected data to a...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Spectrophotometric determination of uranium in water samples after cloud point extraction using nonionic surfactant Triton X-114
A cloud point extraction process using the nonionic surfactant Triton X-114 to extracturanium from aqueous solutions was investigated. The method is based on the complexationreaction of uranium with Arsenazo III and micelle-mediated extraction of the complex. Theoptimal extraction and reaction conditions (e.g., pH, reagent concentration, effect of time) werestudied, and the analytical character...
