چکیده مقاله
The transfer method was investigated using direct- potential-reinforced bulk-liquid membrane transport (RE-BLMT) for extraction of dopamine. The purpose of this study was to evaluate the ability of the mentioned method to isolate and transfer dopamine. The RE-BLMT method is a simple method based on a combination of two known EME extraction approaches and a BLMT transmission [1]. Variables such as pH, phase and receiver, ion strength, BLM type and volume, extraction time, applied voltage and electrode type were studied. The linear calibration curve of the method was obtained at a range of 0.2-4 μg-mL-1 with a coefficient of correlation of 0.99. The relative standard deviation (RSD) for the seven replications was 4.8 μg / mL and the transfer efficiency was 90%. The RE-BLMT method was used to transfer and determine the concentration of dopamine in drug samples.
