Abstract |
Herein, for the first time, research on water/oil emulsion droplet by electrochemical analysis has been reported. By the use of blocking of the single emulsion droplet, water/1,2-dichloroethane emulsion droplets collided with an ultramicroelectrode (UME) leading to the “stair-case” current decrease. Each “stair-case” current decrease corresponds to the emulsion droplet collision on UME surface. The experimental collision frequency is proportional to the concentration of emulsion droplet. In addition, each water droplet size was estimated from the magnitude of the “stair-case” current decrease with simulation data. Results obtained from the collision signals provide information about the single droplet size (nano- to micro-) and a pM concentration of the water emulsion in organic continuous phase. |
