Monosegemented Flow Potentiometric Titration for the Determination of Chloride in Milk and Wine
Este trabalho descreve um procedimento automático em fluxo monossegmentado para titulação potenciométrica aplicado à determinação de cloreto em leite e vinho. O sistema de fluxo foi desenvolvido com base em uma válvula solenóide de 6 vias, controlada por um microcomputador através de um programa escrito em VisualBasic 3.0. Um eletrodo indicador tubular de Ag 2 S seletivo a Cl e um eletrodo de r...
متن کاملA Convenient Method for Potentiometric Titration of Chloride Ions
A convenient reference cell and method of potentiometric determination of chloride ions with silver nitrate is described. The method is accurate to about +/- 0.02 ml. 10(-4)M silver nitrate.
متن کاملSequential Potentiometric Determination of Nitrate and Chloride in Vegetables
A rapid and simple sequential potentiometric method is described for the determination of nitrate and chloride ions in vegetables, by using home-made ion selective electrodes. The extraction of both ions from the vegetable samples was effected by magnetic stirring of the samples during 30 min in water at room temperature. Direct Potentiometry was used as analytical technique for measurement. Th...
متن کاملSequential injection titration with spectrophotometric detection for the assay of acidity in fruit juices.
A simple sequential injection analysis (SIA) with spectrophotometric detection for an assay of acidity in fruit juice was investigated. An alkaline reagent (sodium hydroxide), a sample and an indicator (phenolphthalein) were first aspirated and stacked as adjacent zones in a holding coil. With flow reversal through a reaction coil to the detector, zone penetration occurred, leading to a neutral...
متن کاملPotentiometric titration and conformational change in pepsinogen.
Potentiometric titrations of pepsinogen as functions of ionic strength and temperature were studied. It was found that the ionic strength has a minor effect on the titration behavior of the protein. The maximum values of the buffering capacity in the pH range of 6.0 to 9.0 were found at pH values corresponding to those at which a conformational change of the protein occurs as determined by opti...
