In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.
determination of barium as tio2 factory. This method involves bombarding the sample with X-rays and measuring the resulting fluorescence spectrum. XRF offers fast analysis times and requires minimal sample preparation, making it suitable for on-site testing. However, its accuracy may be affected by matrix effects and interference from other elements.In the application of lithopone in ink industry, lithopone has fine particles, loose structure, good fineness and good paint adhesion, so it can be well combined with other colors in the composition of ink.
