Sodium Hydrosulfite has the formula Na2S2O4 and is also called Sodium Dithionite, as it is the sodium salt of dithionous acid. It is a white crystalline powder, whose bulk density is about 0.85 - 0.95 kg/ l. Sodium Hydrosulfite has a strong reducing and bleaching power and is therefore used in the paper and textile industry.
8.4g Sodium Bicarbonate 17.4 g Sodium Dithionite 5.9g Trisodium salt of Citric Acid (sodium citrate) Once mixed, the minerals are immersed in the solution. The cleaning action can be accelerated by placing in an ultrasonic cleaner. This solution is not appropriate for indoor use because, once mixed, there is a strong odor of rotten eggs.
A method for the preparation of a composition for use in paper making or pigment coating compositions containing also an optical brightening agent (OBA) includes the steps of (a) preparing an aqueous suspension of a clay mineral comprising a kaolin particulate material; and (b) treating the clay mineral by addition of a treatment agent which reduces the harmful effect of metal ions present in ...
