Abstract: Apparatus and method are provided for remediating trichloroethylene-polluting soils by integrated rotated migration and PRB. The apparatus includes a device of electrokinetic remediation, a PRB and a device of injection of surface active agents. The main components of the device of electrokinetic remediation and PRB include cathode, anode, electrode chamber and PRB. A liquid injection pipe is installed between various electrodes and PRBs. The operation of each device is controlled by each control system. The disclosure integrated rotated migration and PRB for remediating contaminants. Surface active agents is helpful for dispersing TCE from soil. The arrangement of the electrode and the PRB greatly shortens distances and time of pollutant migration, which accelerate the speed of remediation and reduce post-processing procedures. In the process of treatment, the three technical methods promote each other, and have the advantages of good repair effect, short time, no secondary pollution and easy operation.

Abstract: Apparatus and method are provided for the treatment of uranium-contaminated soil by using comprehensive joint technology. The apparatus include the pumping system, the electrokinetic remediation system, elution system, remediation-separation system and recharge system. The remediation technologies (i.e. chemical, photolysis and electrokinetic) are used to remedy the uranium-contaminated soil. First, extract uranium from the contaminated areas and make the ionized uranium extract from the soil phase to the solution phase. Then, use the electrokinetic remediation technology to drive uranium enrichment electromigrate to near the anode. Finally, return the repaired-soil and groundwater back to anode area and recharge well, respectively. This comprehensive joint apparatus can reduce the uranium volume in the contaminated soil or water, and recycle the obtained uranium, which are cleaning processes and have no secondary pollution.

Abstract: Methods of forming a cobaltocenium-containing polymer are provided through polymerizing a plurality of cobaltocenium-containing monomers via controlled radical polymerization or controlled ring-opening polymerization. Each cobaltocenium-containing monomer comprises a cobaltocenium moiety covalently connected to a polymerizable group. Cobaltocenium-containing monomers are also provided that include a cobaltocenium moiety covalently connected to a polymerizable group. Cobaltocenium-containing polymers are also generally provided, such as the polymers formed according to any of the methods or from any of the monomers discussed herein. Methods are also generally provided for exchanging an anion associated with a cobaltocenium side group of a cobaltocenium-containing polymer with a new anion.
