The total amount of Cu2+ released to solution after cation-exchange reaction measured by ICP-MS.
C DNA = 0 | C DNA = 1.0 × 10−9 M | C DNA = 1.0 × 10−8 M | |
---|---|---|---|
Cu2+ concentration applied cycle I route (M) | <0.000 | 7.19 × 10−6 | 2.78 × 10−5 |
Cu2+ concentration applied cycle I + cycle II route (M) | <0.000 | 3.31 × 10−5 | 1.22 × 10−4 |
