In conclusion, the determination of barium as TiO2 in industrial factories requires a combination of analytical techniques depending on the specific requirements of the application. Each method has its own advantages and limitations, and the choice of technique should be based on factors such as accuracy, precision, cost, and turnaround time. With the proper selection and implementation of these techniques, manufacturers can ensure the quality and safety of their products while complying with environmental regulations.
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.
The zinc content in the electrolytic zinc acid leaching residue in the leaching step is 5% to 35%. In the purification step, after the primary immersion liquid is added with ammonium persulfate for one oxidation, a polyacrylamide coagulant is added before the filtration separation. It is used for flocculation to produce arsenic and iron coprecipitation to remove harmful elements.
