Extraction of dopamine by DC potentially-reinforced bulk-liquid membrane transport (PR-BLMT) combined with UV- Vis spectrophotometric method

The transfer method was investigated using direct potential-reinforced bulk-liquid membrane transport (PE-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. Using this method linearity ranged from 0.2 to 4 μg mL-1 with the coefficient of correlation of 0.99. The relative standard deviation (RSD) for the seven replications was 4.8% and the transfer efficiency was 90%. The RE-BLMT method was used to transfer and determine the concentration of dopamine in drug samples.
