| titleOfInvention | A kind of measure the electrochemical method of free residual chlorine in water |
| abstract | A kind of measuring the electrochemical method of free residual chlorine in water, compound concentration is C 1 , C 2 , C 3 …C n NaClO standard solution, it is not less than 10.0 with NaOH solution regulation pH, inject the solution room to be measured of measuring cell, after OCP between platinum electrode and silver electrode is stable, the electrode potential maintaining platinum electrode is 0.300V ± 0.05mV, with electric current density i (t) between platinum electrode and silver electrode 6 as y-axis Mapping for x-axis, straight slope is K, with C 1 , C 2 , C 3 …C n With corresponding K 1 , K 2 , K 3 …K n Make standard curve.Same step measures the K value of water sample to be measured, and substitution standard curve is tried to achieve C value and is water sample free residual chlorine content.Using this method to measure free residual chlorine in water, have measurement accurately, rapidly, be susceptible to interference, simple to operate, device is easy, with low cost, the plurality of advantages such as maintenance cost is low. |
