Preserving the Mary Rose | Feature | Chemistry World

This would involve spraying the hull with strontium carbonate nanoparticles, which react with the sulfur in the hull to form stable strontium sulfates that don’t react with oxygen to produce sulfuric acid. Initial studies have shown that these nanoparticles can impregnate wood and will react with the sulfur to form unreactive species.

Tri Sodium Phosphate – horsanchemi

Washing powder (also hydropurifying industry) eliminates the hardness of the water, and is also a good option for preserving substances. Sodium phosphate is a white powder known as sodium phosphate, pentadium triphosphate, trisodium phosphate and STPP, and is used to obtain water hardness, especially in washing powder and also in the preparation of foodstuffs.
