Abstract
The method comprises introducing a predetermined amount of PM in a base as a sorbent under conditions allowing its quantitative sorption from standard solution. The basis dispersed silica gel is used, with uniform fractional composition, chemically modified with sulfur-containing groups. Sorbate after separation from the solution is calcined at 550-800 ° C to form on the surface of the sorbent metal nanoparticles and PM content is determined in obtained material with the necessary accuracy.
