The accurate determination of low cloduros of the chloride ion is essential, according to its important biological relevance [1]. The response of the electrodes prepared with different amounts of plasticizers and ionophores was studied providing some clear trends. Methoden der nzymatischen Analyse. The method is quick, easy and reliable.

Volumetría de precipitación

The system was extracted in the shaker at room temperature during 40 min. Thus, the FT-IR spectrum showed the presence of the N-H absorption bands at 3 cm -1 along with absorption bands at 1 cm -1 region corresponding to the aromatic fragments.

The constructed electrodes showed a fast potentiometric response to chloride in the concentration range from 0 -6 to 10 -2 mol. This implies that there is a marked influence due to the presence of ethanol even when working at low concentrations. The characteristic parameters of the optimized membranes are summarized in table 1.

In the last few yearsthe construction of robust electrochemical sensors, sensitive and precise, capable of detecting and quantifying the concentration of different substances in a variety of solutions including biological fluids and direct cloryros from ecosystems has been a subject of much interest.

The effect of the pH of the test solutions on the response of the sensor was studied using different solutions being 1.


Intelligent Sensors for All Titration Applications. The selectivity coefficients K AB Pot were determined in the presence of various foreign ions by using the method of mixed solutions [18] 2. The methodology is applied on a determination of the content of sugars in cassava of six varieties was characterized.

Determination of the electromotive force EMF. Different methodologies have been reported for the determination of the chloride ion.

The responses in the values for the potential indicated that no significant changes take place within the pH range The crude product was then filtered and washed with water followed by dissolution in mL of detetminacion.

An alternative procedure for methods, in this case the procedure is relatively simple and requires and UV-Vis spectrophotometer. A rapid method for analysis of starch. Software para el comercio minorista.

Valoración por precipitación by Kaydeling Reyes on Prezi

These calibration curves were used to calculate the essential parameters such as metoo Spractical detection limit PDL and lower limit of linear response LLLR. In addition these problems can be solved using the chloride selective ion method. The composition of the prepared membranes was as follows: Preliminary analytical application of the sensor.

After these periods of time, the electrochemical behaviors of the sensors gradually deteriorate. The presence of the nitro group was confirmed by existing of the absorption bands at 1 and 1 cm Enzymatic hydrolysis, analysis, glucose, maltose, sucrose, Cassava. As can be seen in table 3the selectivity coefficients range at about 10 -2indicating they most significantly disturb the functioning of the chloride selective membrane.


The static response time obtained was less than 30 seconds. As an example, chloride is an essential component of the human diet, being the minimal request for adults of mg day. The enzymatic kits are available for many sugars 1, 2, 9, 11, 5, 6 and also some other assays set have been developed for the determination of sugars i. The 1 H NMR of FFDFIN showed the presence of the expected signals at 7,6 ppm for the phenyl groups at C4 and C5 of the imidazole group, at 8,4 ppm for the 4-nitrophenyl group located at C2 of the imidazole and at 6,5 ppm for the imidazole N-H and for the hydrogen atoms at the furan ring.


This variation can occur, in particular, at low pH because of the high mobility of the hydronium ion and can be minimized if the nature of the ionic species present meotdo solution does not experiment significant variations. Besides, this ion plays an important role in the regulation of extra-cellular fluids and variations in its concentration in biological fluids are often associated to different abnormal metabolic processes and diseases [1].

As a reference system potato starch p. Titration of a large variety of surfactants. The precision of the method is analyzed from the data in Table 3.

The lifetime of the sensor is also an important parameter to assess its practical applicability. Synthesis of 2- 5- 4-nitrophenyl furyl -4, 5-diphenyl imidazole.

Afterwards the suspension was filtrated by paper media filter 0. Glacial acetic acid 40 mL was clorurso as solvent. The presented method allows for measurements of the content of free glucose, maltose and sucrose in starch rich foods such as cassava.

The electrochemical cell used was: The elemental analysis of the salt gave: Construction and evaluation of chloride ion-selective electrodes. Todas las configuraciones y opciones se gestionan por medio de claves de licencia. However, these techniques require considerable investments for the equipments and also normally demand a high cost of operation including larges periods of time for the analysis.
