Add Trichloroisocyanuric Acid (TCCA) to the aqueous solution

In one embodiment, the method for in situ formation of aqueous iodine may include reaction of sodium or potassium iodide with molecular chlorine produced by addition of Trichloroisocyanuric Acid (TCCA) to the aqueous solution. 
The resulting chemical reaction is shown in equations as follow. 
For example, by treating the resin to two, three or more processes of in situ iodine formation (i.e., KI plus Trichloroisocyanuric Acid (TCCA)), the halide production is minimized. Alternatively, the resin may be treated to in situ formed iodine in a continuous flow process. By treating the resin with in situ formed iodine and then removing the supernatant, any residual chloride or bromide is removed with the supernatant. This may allow for the reduction of the use of a Cl? or Br? scavenger compound, such as silver or lead ions with a concomitant cost savings.
Analysis the parameters of Trichloroisocyanuric Acid (TCCA) synthesis process, we successfully developed a  new technology of continuous process for the production of TCCA, compared with the traditional process, this new method has advantage of production safety, efficient and energy-saving features.
