Life seawater electrolysis decontamination is generated by electrolysis of seawater strong oxidizing sodium hypochlorite, sodium hypochlorite by strong oxidation, bacteria enter the body to destroy the proteases, thereby killing microbes in seawater, spores. Titanium anode electrolysis of seawater is the core component of the preparation of sodium hypochlorite, have long life (≥5 years), high current efficiency (> 80%), low chlorine evolution potential ≤1.12V, strengthen life ≥120hr, polarization ≤40mV. Conditions: Water: salinity ≥30PSU temperature: 0-35 ℃ current density: 1400-1500A / m2 electrolyte flow rate: 1m / s Ambient temperature: -10 ℃ to 50 ℃
