Trimercapto S -triazine trisodium salt is a chemical compound from the group of triazines .

Extraction and presentation

The trimercapto- s- triazine trisodium salt can be obtained by reacting cyanuric chloride with sodium sulfide at temperatures from 20 to 70 ° C. in the basic range.

use

Trimercapto s -triazine-trisodium salt is used for the precipitation of complex-forming, mono- and divalent heavy metals, such as. B. silver, cadmium, copper, mercury, nickel and lead from wastewater are used. The use of the compound has increased in particular for the precipitation of mercury in coal-fired power plants.
