摘要：

The selective detection of dopamine in the presence of ascorbate is demonstrated based on the voltammetry of dopamine transfer across the interface between two immiscible electrolyte solutions (ITIES) facilitated by an organic-phase ionophore; ascorbate transfer does not occur, leading to highly selective detection of dopamine in the presence of excess ascorbate.
