Abstract

The invention relates to a device for continuously removing metal ions from a feed solution and a use method. According to the device, a free-flow electrophoresis technology and ion-exchange chromatography are combined, so that the efficient and continuous removal of the metal ions is achieved. The device comprises parts such as a separation chamber, an adsorption chamber and an electrode system. The device and the use method have the advantages that the device is low in manufacturing cost, simple in structure, easy to assemble and convenient to operate; the separation chamber is large in size, so that the feed solution treatment capacity is high; the metal ions in the feed solution can be continuously removed; the feed solution does not directly flow through a resin cavity, so that secondary pollution cannot be caused.

Description

technical field [0001] The invention relates to the technical field of free-flow electrophoresis separation, in particular to a device and a method for continuously removing metal ions in feed liquid. Background technique [0002] With the continuous development of our country's social economy, a large amount of metal wastewater is discharged into the environment, causing water and soil pollution, and seriously threatening human life and health. At present, the traditional methods for removing metal ions in water mainly include ion exchange, electrolysis, and precipitation. Although these methods can achieve a certain separation effect, they are often unsatisfactory due to the cumbersome process and easy to cause secondary pollution. [0003] Free-flow electrophoresis is a semi-preparative separation technology, which has the advantages of continuous separation, multiple separation modes, no solid support medium and mild separation conditions. Free-flow electrophoresis is a...
