Our data, concerning extraction of nanoparticles of metals (Mn, Cu, Zn, Ag) by free-floating hydrophytes, is well consistent with these of other scientists declared for the ability to remove Mn, Cu, Zn, and Ag in ionic form, especially by Pistia [18 21] and Salvinia [22, 23].
The almost complete extraction of nanoparticles observed at moderate heating with a standard magnet contrasts to the incomplete withdrawal demonstrated earlier by nanoparticles with a physisorbed block copolymer PNIPAM shell architecture or by polydisperse PNIPAM-grafted nanoparticles.
Thus, the electrosynthesis of CdSe in electrolytes based on a nitric acid–hydrochloric acid mixture with simultaneous extraction of ultrafine nanoparticles into xylene may be a promising way of preparing concentrated colloidal solutions of such nanoparticles since the amount of extracted small nanoparticles increases by factor of ten compared to using electrolyte based on the sulfuric acid.
In the layer of this emulsion, the synthesis and simultaneous extraction of CdSe nanoparticles take place.
Cell viability in response to the liquid extraction of LSMO nanoparticles ranged from 91.3% to 98.2% (Fig. 8).
However, the extraction conditions (time, temperature, chemical concentration) are fundamental to the efficient extraction of cellulose nanoparticles with the required characteristics [ 46].
Recently, the use of nanoparticles in extraction columns has gained increasing attention due to their potential to enhance mass transfer processes.
In addition, the magnetic nanoparticles show no toxicity to the tested cells, NIH 3T3, as determined from the result of cell viability in response to the liquid extraction of the magnetic nanoparticles.
The differences in extraction of individual metal nanoparticles from aqueous solutions by different types of hydrophytes as well as plant species specificity regarding the studied metal nanoparticles were revealed.
Significant extraction of zinc nanoparticles from mixture of investigated colloidal solutions of nanoparticles was observed in five variants.
