What are the benefits of TMT 15®?
TMT 15® has very favourable toxicological and ecological properties compared to all other precipitating agents. Besides the very low acute toxicity (LD50 7878 mg TMT 15®/kg) TMT 15® is practically not toxic for fish (LC0 13720 mg TMT 15®/l) and water fleas (Daphnia magna, EC50 4224 mg TMT 15®/l). TMT 15® is not mutagen and shows no acute toxicity against bacterial population. The toxicity to green algae is low (IC50 273 mg* TMT 15®/l). TMT 15® has a good storage stability and is not considered as a dangerous substance according to the transport regulations. TMT 15® is a safe product. Should TMT 15® accidentally come into contact with acids only minor amounts of hydrogen sulphide and no carbon disulphide are released and the acidic form of TMT 15® (TMT-H3) would precipitate, which is practically insoluble in water. This reaction is reversible and the TMT sodium salt can be achieved again by the addition of caustic soda.
