  • According to the EFSA's Expert Panel on Food Additives and Flavorings 2021 opinion regarding titanium dioxide, it could not rule out a concern for genotoxicity from ingestion of the material based on a perceived gap in data on this risk, which serves as the basis for current ban, said a March report on the decision.

  • That's where the r 298 titanium dioxide factory shines. By adopting innovative technologies such as pyrolysis and hydrochlorination, the factory has been able to reduce energy consumption by up to 50% while also significantly decreasing the amount of waste produced By adopting innovative technologies such as pyrolysis and hydrochlorination, the factory has been able to reduce energy consumption by up to 50% while also significantly decreasing the amount of waste produced By adopting innovative technologies such as pyrolysis and hydrochlorination, the factory has been able to reduce energy consumption by up to 50% while also significantly decreasing the amount of waste produced By adopting innovative technologies such as pyrolysis and hydrochlorination, the factory has been able to reduce energy consumption by up to 50% while also significantly decreasing the amount of waste producedr 298 titanium dioxide factory. These advances have not only made the production process more environmentally friendly but have also resulted in cost savings for the company.
  • The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.
