- Аннотация: The adsorption of iron(11) tris(1,10-phenanthroline) on the glass surface of laboratory ware from solutions has been studied by thermal lens spectrometry at a level of nanogram amounts. The effect of glass pretreatment on the fraction of the adsorbed substance has been studied, and the most appropriate variant of the pretreatment has been selected. The kinetics of iron(11) tris(1,10-phenanthroline) adsorption on the surface of laboratory glass has been studied, and an adsorption isotherm has been constructed for nanograin chelate contents of the solution. The process is most closely approximated by the Freundlich equation. Based on the obtained data, a procedure has been proposed for the preparation of solutions for constructing calibration relationships that can be used in thermal lens measurements of trace amounts of analytes. This procedure takes into account the loss of substances at the surface of laboratory glassware.
