titania tio2

In conclusion, China's titanium dioxide industry, while contributing significantly to the economy, is also confronted with the challenge of sustainable water management. The combination of strict regulations, technological innovation, and green chemistry initiatives is shaping the future of this sector, ensuring responsible production and the preservation of water resources. As the industry continues to evolve, it is crucial to maintain a balance between economic growth and environmental protection, harnessing the potential of TiO2 for both industrial use and environmental remediation.

For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.

In addition, with the increasing demand for zinc compounds and lithopone, the continuous exploitation of zinc resources in China, the increasingly poor, fine and complex mineral resources, the comprehensive utilization and environmental protection requirements continue to improve, people have begun to study the recovery of low-zinc raw materials. Use technology. The so-called low-zinc raw materials are mainly low-grade zinc oxide ore, but in addition to low-grade oxidation In addition to zinc in zinc ore, zinc is also present in the acid leaching residue.
