Figure Lengend Snippet: SP-ICP-MS analysis of AgNPs formed in whey dispersions (6.3 g/L) spiked with Ag + ions. The top panels ( A , B ) show particle number concentrations and mass concentrations, respectively. The bottom panels ( C , D ) display the background equivalent diameters (BEDs) and mean particle diameters. Each data point represents the average of three independent samples, with error bars indicating standard deviations. The legend in panel ( A ) also applies to panel ( C ). In panels ( B ) and ( D ), the black line represents the water control containing 100 µg/L Ag⁺ ions while red, blue, and green lines correspond to whey dispersions spiked with 100, 500, and 1000 µg/L Ag⁺ ions, respectively.
Article Snippet: For all inductively coupled plasma optical emission spectrometry (ICP-OES) and mass spectrometry (ICP-MS) analyses, OptimaTM grade nitric acid and hydrochloric acid (Fisher Scientific) were used.
