Cloud Point Extraction and Spectrophotometric Determination of Uranium (VI) in Water Samples after Mixed Micelle-Mediated Extraction Using Chromotrope 2R as Complexing Agent
A rapid, selective and sensitive method for the preconcentration and determination of uranium (VI) by cloud point extraction (CPE) was developed. The method was based on the color reaction of 5.00 ng mL uranium (VI) with 1.5×10 mol L of chromotrope 2R in the presence of 0.015 mol L potassium iodide at pH 8 in HEPES buffer and mixed micelle-mediated extraction of complex. The mixture of a nonion...
متن کاملInsights into cyclostome phylogenomics: pre-2R or post-2R.
Interest in understanding the transition from prevertebrates to vertebrates at the molecular level has resulted in accumulating genomic and transcriptomic sequence data for the earliest groups of extant vertebrates, namely, hagfishes (Myxiniformes) and lampreys (Petromyzontiformes). Molecular phylogenetic studies on species phylogeny have revealed the monophyly of cyclostomes and the deep diver...
متن کاملCryptanalysis of 2R- Schemes
In this paper, we study the security of 2R− schemes [17, 18], which are the “minus variant” of two-round schemes. This variant consists in removing some of the n polynomials of the public key, and permits to thwart an attack described at Crypto’99 [25] against two-round schemes. Usually, the “minus variant” leads to a real strengthening of the considered schemes. We show here that this is actua...
متن کاملSpectrophotometric methods for the determination of anti-emetic drugs in bulk and in pharmaceutical preparations.
Four rapid, simple, reproducible and sensitive methods (A-D) for assaying domperidone (I) and metoclopramide (II) in a bulk sample and in dosage forms were investigated. The first and second methods, A and B, are based on the oxidation of I and/or II by Fe3+ in the presence of o-phenanthroline (o-phen) or bipyridyl (bipy). The formation of tris-complex upon reactions with Fe3+-o-phen and/or Fe3...
متن کاملCryptanalysis of \2R" Schemes
The function decomposition problem can be stated as: Given the algebraic expression of the composition of two mappings, how can we identify the two factors? This problem is believed to be in general intractable [1]. Based on this belief, J. Patarin and L. Goubin designed a new family of candidates for public key cryptography, the so called \2R schemes" [10, 11]. The public key of a \2R"-scheme ...
