Infrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO2NPs spectra, such as a wide peak in 450–1028 cm−1 related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm−1 and 3400 cm−1, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO2NPs showed signs of binding between compounds. The OH bending peak (1634 cm−1) corresponding to bare nanoparticles disappeared, and the NH2 bending band characteristic of vitamin B2 appeared (1650 cm−1). The IR spectrum of vitaminC@P25TiO2NPs also showed signs of successful functionalization. Bands at 1075 cm−1; 1120 cm−1; 1141 cm−1 were observed, which are originated by C
O-C vibrations present in the vitamin C. The intense band at 1672 cm−1 is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm−1 is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm−1 are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO2NPs and the vitamins [35].
The overseas demand for Chinese TiO2 rose up by about 17% in 2016, which enabled an export increase of the manufacturers in China. As a fact, Chinese TiO2 is highly demanded in overseas markets, due to the comparable small price of the suppliers. The export of TiO2 is responsible for about one-third of the total output in China.
- The journey of titanium dioxide begins with the mining of ilmenite, rutile, or anatase, which are the three main titanium ore minerals. These minerals are then transported to a titanium dioxide factory where they undergo a series of processing steps.

The European Commission banned titanium dioxide as a food additive in the EU in 2022 after the European Food Safety Authority (EFSA) conducted an updated safety assessment of E171 and concluded the panel could not eliminate concerns about its genotoxicity.
Jinan Yuxing Chemical Co., Ltd. Affiliated to China National Chemical New Materials Co., Ltd., it is a tertiary company under China National Chemical Corporation, the largest comprehensive chemical manufacturer in China. It is also one of the most modern manufacturers of sulfuric acid titanium dioxide manufacturers in the Asia-Pacific region. This TiO2 factory has more than 50 years of experience in the development and manufacture of titanium dioxide, and the “Shengsheng” brand titanium dioxide is well-known at home and abroad.

There seems to be a lot of misunderstanding about titanium dioxide, which can be used as a colorant in foods. While headlines may suggest titanium dioxide is a health concern, scientific research has actually shown titanium dioxide to be safe. So what is it used for and why is it used? Read on to learn more!

One of the key factors that affect the precipitation of titanium dioxide is the precipitation percentage, which is the percentage of titanium sulfate that is converted to titanium hydroxide during the reaction
. The precipitation percentage is influenced by a variety of factors, including the concentration of titanium sulfate, the pH of the reaction mixture, the temperature, and the reaction time.precipitation of titanium dioxide equation factory
