carbonate ions and complex up to 36 mol% of the total calcium (Fig. Id). The substitution of carbonate ions is likely to occur in the outer layer of the ACC nanoparticles, and would correspond to a shell of nm. This eITect is observable owing to the nanoscale dimensions of the ACC nanoparticles, where the fraction of charged
Calcium carbonate is the active ingredient in agricultural lime and is created when . Calcium Carbonate Nanoparticles / Nanopowder(CaCO3, 98+%, 15 . Industrial Coatings—Calcium carbonate nanoparticles and powders are frequently found in industrial appliions that require protective coating.
The global nano calcium carbonate market size was USD 4, million in 2015 and is expected to witness growth owing to rising demand from enduse industries including rubber, plastic, and paper.
The synthesis of precipitated calcium carbonate nanoparticles with the use of double water in oil emulsion has been developed. Restricting the mass of calcium ions present in the system makes it possible to predict particle size precipitated. A model was developed to calculate the concentration required to synthesize a desired particle size.

Process for the production of precipitated calcium carbonate particles, structured at the nanoscale, by carbonation of milk of lime in the presence of a crystallization controller selected from the following list: polyaspartic acid, dioctyl sodium sulphosuccinate, polyacrylic acid, the molecular weight of which is between 500 and 15 000, and citric acid.
industrial effluents has become an important area of research. Precipitated Calcium Carbonate (PCC) nanoparticles are one of the cheapest nanomaterials, which can be used to remove various pollutants present in aquatic environments. We have, therefore, used PCC nanoparticles to remove methylene blue in aqueous effluents.
