 5公斤氟钠钠。 In the leaching step, each cubic meter of ammonia - ammonium sulfate solution was added 0. 3~0. 5kg sodium fluorosilicate. The purpose is to make the ammonia leaching reaction easier and more thorough. Adding an appropriate amount of sodium fluorosilicate can break the package of zinc-containing particles by a kind of ultrafine particles such as calcium hydroxide formed during the dissolution and conversion process of calcium sulfate in the ammonia solution. , the ultra-fine particles are layered and peeled off to achieve leaching.

Titanium dioxide (TiO2) is commonly applied to enhance the white colour and brightness of food products. TiO2 is also used as white pigment in other products such as toothpaste. A small fraction of the pigment is known to be present as nanoparticles (NPs). Recent studies with TiO2 NPs indicate that these particles can have toxic effects. In this paper, we aimed to estimate the oral intake of TiO2 and its NPs from food, food supplements and toothpaste in the Dutch population aged 2 to over 70 years by combining data on food consumption and supplement intake with concentrations of Ti and TiO2 NPs in food products and supplements. For children aged 2-6 years, additional intake via ingestion of toothpaste was estimated. The mean long-term intake to TiO2 ranges from 0.06 mg/kg bw/day in elderly (70+), 0.17 mg/kg bw/day for 7-69-year-old people, to 0.67 mg/kg bw/day in children (2-6 year old). The estimated mean intake of TiO2 NPs ranges from 0.19 μg/kg bw/day in elderly, 0.55 μg/kg bw/day for 7-69-year-old people, to 2.16 μg/kg bw/day in young children. Ninety-fifth percentile (P95) values are 0.74, 1.61 and 4.16 μg/kg bw/day, respectively. The products contributing most to the TiO2 intake are toothpaste (in young children only), candy, coffee creamer, fine bakery wares and sauces. In a separate publication, the results are used to evaluate whether the presence of TiO2 NPs in these products can pose a human health risk.

One of the key factors to consider when choosing a TiO2 supplier is the quality of the product they offer. High-quality TiO2 should have excellent brightness, opacity, and dispersion properties, as these characteristics directly impact the final appearance and functionality of the end product. An excellent white TiO2 supplier will have a reputation for consistently producing top-quality products that meet or exceed industry standards.
