| Abstract: | The present invention discloses a process to reduce the content of iodide and bromide in harvested solar salt (I- 100 ppb & Br- 200 ppm) during solar salt production in solar salt pans, which cannot be achieved through other means of purification such as washings. The process comprises of chemical treatment of brine either with trichloroisocyanuric acid (TCCA) alone or combination with hydrochloric acid. The process is suitable for both sea & sub-soil brines used for common salt productions and can be implemented in the existing salt works without any additional alternation of salt works. The method is particularly useful for production of high purity salt desired for chlor-alkali industries. |
