Figure 7. (A) Concentrations of ionic silver in water and a detergent solution measured by ISE and filtration/ICP−MS as a function of the simulated home laundering cycle. (B) Silver fraction in water and a detergent solution determined by ICP−MS as a function of the laundering cycle. The comparisons of the proportions of ionic silver measured by (C) ISE and (D) filtration/ICP−MS relative to the total silver in water and a detergent solution with literature values.
