摘要
由电化学理论可知,在电化学体系中,电极与溶液的交界处存在双电层.双电层具有电容的特性,即可以充电或放电,其在电极一侧的充电电荷由电极上的电子或正电荷提供。
Based on the capacity characteristics of electrical double layer, a new separation method--charge concentration is proposed, and a preliminary experimental study is made. The separation unit is a column packed with powdered activated carbon. Two disc electrodes with some well - distributed apertures are placed separately on the top and under the bottom of the activated carbon. Hard water is fed continuously from the top of the column and the conductivity of the effluent from the bottom is measured with a conductometer. The measured results indicate that ions in water can be removed by applying direct current to the electrodes and then a concentrated solution can be obtained by turning off the current.
