Rhodamine B is a synthetic dye used for coloring textiles, paper and ceramics. In addition, also often ingredients in food such as crackers, syrups, candy, cakes, lipsticks. The accumulation of the body can cause liver, kidney lymph damage. this study, modified carbon paste (EPK) electrode with molecularly imprinted polymers (glutamic acid) was developed determination rhodamine using potentiome...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

this study aimed to determine the relationship between suturing and electro-cautery methods of post-tonsillectomy homeostasis in imam khomeini hospital- kermanshah. an analytical study was performed on admitted patient's profiles from 2002-2004. data collection sheet was applied to extract all variables. descriptive and inferential statistics were used for data analysis. during that period 915 ...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

OBJECTIVE Analysing the fundamental methodological aspects which should be considered when drawing up calibration procedure for electro-medical equipment, thereby permitting international standard-based accreditation of electro-medical metrology laboratories in Colombia. METHODS NTC-ISO-IEC 17025:2005 and GTC-51-based procedures for calibrating electro-medical equipment were implemented and t...

The main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. The reaction time and the rheological properties of samples during the polymerization were studied. The samples were characterized by Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimeter (DSC) and FT-IR spectrometer. The melt flow behavior and ...

The basic electro-kinetic process is defined by forced/induced movement of target pollutants in soil/sand medium under applied electric field low strength between electrodes of opposite polarities. There are several specific mechanisms that contribute to this movement of pollutants. However, one study suggested that the most important ones are electro-osmosis, electro migration, and electrophor...
