Spectrophotometric determination of Dalacin phosphate from formulations using reduce atomic absorption of calcium ion by phosphate
A simple, sensitive and accurate method for spectrophotometric determination of Dalacinphosphatehas been established. The method is based on the reduction of atomic absorptioncalcium ion by phosphate. Because, there is a phosphate mole in every Dalacin mole structureand with measurement of phosphate, Dalacin is beyond measurement too. Therefore, the reactionbetween acidic hydrolysis products of...
متن کاملHPLC analysis of aliphatic sulfonate surfactants using ion-pair detection.
A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, N-methyl-2,2'-dipyridinium iodide and N,N'-dimethyl-2,2'-dipyridinium diiodide, were used as the visualization reagents, forming ion-pair complexes with the sulfonate surfactants. This a...
متن کاملMethods Development Using Ion-Pair Chromatography with Suppressed Conductivity Detection
INTRODUCTION Mobile-phase ion chromatography (MPIC) is a technique that combines ion-pair chromatography with suppressed conductivity detection. Ion-pair chromatography is commonly used in combination with UV detection, in which case it is referred to as reversedphase ion-pair chromatography (RPIPC). MPIC has the advantage of using conductivity detection, which serves as a universal detection m...
متن کاملize-fractionation of silver nanoparticles using ion-pair extraction in a ounter-current chromatograph
Size separation of silver nanoparticles was investigated in counter-current chromatography (CCC) based on a unique step-gradient extraction process. Carboxylate anions were modified on silver nanoparticles to produce water-dispersible nanoparticles. The aqueous nanoparticles were readily transferred to the organic phase (toluene/hexane = 1:1, v/v) together with the phase transfer catalyst, tetr...
متن کاملSolvent Effect upon Ion-pair Extraction of Different Sodium Dyes Using Some Crown Ethers
Liquid-liquid extractive-spectrophotometric studies of sodium ion complexes of 18crown-6(18C6), dibenzo-18-crown-6(DB18C6), 15-crown-5(15C5), and 12-crown-4(12C4) and anionic dyes [4-(2-pyridylazo)-resorcinol monosodium salt monohydrate (PAR), Eriochrom Black T (EBT), and methyl orange (MOR)] and sodium picrate (PICRAT) as the counter ion are described. The overall extraction equilibrium consta...
