Titanium is a metal element found naturally in the environment. When it's exposed to oxygen in the air, it forms titanium oxides that are contained in many minerals, sands, soils, and dusts.
Both calcium carbonate and titanium dioxide play crucial roles in various industries, but they are used for different purposes. Calcium carbonate is primarily used as a filler and pigment, while titanium dioxide is used as a whitening agent and pigment. Additionally, titanium dioxide is more expensive to produce than calcium carbonate due to its synthetic nature and complex manufacturing process.
Thermogravimetric analysis (TGA) was conducted in a sample of vitaminB2@P25TiO2NPs using a TA-THA Q5000 equipment. Temperature ramp rate: 10 °C/min, maximum temperature: 1000 °C, under air. Part of the same sample was mounted on conductive copper tape grids and observed through a Carl Zeiss Sigma scanning electron microscope (SEM) with an EDS probe, at the “Laboratorio de Microscopía y Análisis por Rayos X” (LAMARX) of National University of Córdoba (Argentina).
A 2012 study published in the journal Environmental Science & Technology noted that children are especially exposed to titanium dioxide because of the food that contains the food additive and is particularly marketed to children, including candy and cakes.
