In a preferred technical solution, 3⁄40 2 is added to the Lide powder emulsion of the metathesis reaction step, and the mass fraction of 3⁄40 2 added is 10 to 33%, and the lithopone emulsion is desulfurized (mainly hydrosulfate ion or Elemental sulfur), slowly added 3⁄40 2 until the lithopone emulsion is colorless and transparent. The obtained sulfate ion can be recycled and reused in the production process. The chemical reaction equation is: 43⁄40 2 + HS— + OH— → SO/— + 5H 2 0

Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).
