摘要

The analytical techniques are needed to detect the nanosilver in textiles in direct contact with skin. In this paper, in order to discuss the extraction of nanosilver on the surface of textiles by human skin, we demonstrate the capability of constant temperature oscillation extraction method followed by Inductively Coupled Plasma Spectroscopy (ICP). The sweat and deionized water were selected as extraction solvent simulating the contact process of human skin with textiles. The SEM and TEM analysis shows the existence of nanosilver in the fabric and aqueous extract. ICP analysis shows accurately when analysing silver amounts in the range of 0.05-1.2 mg/L with r~2 values of 0.9997. The percent recoveries of all fabrics were all lower than 44 %.The results shows that the developed method of simulating of human sweat extraction was not very effective. So the nanosilver might not be transferred to human body effectively from the fabric.
