Flow Injection Analysis with Tensammetric Detection for the Determination of Detergents
A straightforward flow injection method for the tensammetric determination of surfactants is described. The flow-through cell is equipped with a mercury-coated gold electrode as the working electrode. Ionic as well as nonionic surfactants can be determined in the concentration range 10~5-104 M. The calibration graph is not linear but with an approximation by a polynomial or a cubic spline funct...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Spectrophotometric determination of catecholamines with metaperiodate by flow-injection analysis
A flow-injection spectrophotometric method for the determination of adrenaline and isoprenaline, based on the reaction with metaperiodate, is described. The calibration graphs are linear up to 2X 10e4 M. Flow injection allows the measurement of 120 samples per hour. The method was successfully applied to the determination of both catecholamines in pharmaceuticals.
متن کاملDetermination of sulphite in wine by flow injection analysis with indirect electrochemical detection
A flow-injection method has been developed for the determination of total sulphite in wine samples. After hydrolysis of bound sulphite, sulphur dioxide is separated from the matrix by means of an in-line gas diffusion module. For detection indirect amperometry is used, with iodine as oxidizing reagent. The iodine can be generated in-line by merging and mixing iodate and iodide solutions, or alt...
متن کاملDetermination of phenylephrine hydrochloride by flow injection analysis with chemiluminescence detection.
A new method is proposed for the determination of phenylephrine hydrochloride by flow injection analysis with direct chemiluminescence detection. The method is based on the oxidation of the drug by potassium permanganate in sulfuric acid medium at 80 degrees C. The calibration graph is linear over the range 0.03-8 ppm phenylephrine hydrochloride, with a relative standard deviation (n = 51, 0.5 ...
