In order to improve the long-term and efficient operation ability of the cathodes in the electrochemical water softening process,Ni-P-PTFE electrode with low surface energy is prepared via chemical deposition method,and used for electrochemical water softening.Results show that Ni-P-PTFE electrodes prepared have good water softening performance,among which Ni-P-PTFE 15 electrode shows the best watrt softening performance,with a softening rate of up to 21.95 g/m2·h in 4 h.In addition,Ni-P-PTFE 15 electrode exhibits the best regeneration performance in a long-term operation,representing a good self-cleaning performance.Under the flushing of simulated rotating water,Ni-P-PTFE electrode can effectively restore its activity and keeps high water softening rate.This electrode with highly activity and long lifespan provides a new idea for the surface design of electrochemical water softening cathode materials.
