To determine silver in technological solutions by the atomic absorption method along the 328.1 nm line, average samples of 1 L in volume were taken every 3 hours and evaporated to 10 ml. Construct a graph of changes in the silver content in solutions during the day according to the readings of the device for samples:
Time of day, h 0-3 3-6 6-9 9-12 12-15 15-18 18-21 21-24
Instrument readings (T,%) 85 89 78 51 70 85 89 90
using instrument calibration with standard solutions:
Silver content, μg/ml 0 0.4 1.0 2.0 4.0
Instrument readings (T,%) 100 93 83 69 47.5
