文摘
- •
The Zn2 + inhibition mechanisms on CaCO3 precipitation was investigated in this work.
- •
The Zn2 + efficiency at very low concentration is a well established experimental fact.
- •
Novel mechanism: Zn2 + - OH− reactivity in the 7–9 pH range inhibits CaCO3 ↓.
- •
Highlight of the Zn2 + synergetic double inhibiting effect in pre and post-precipitation
- •
Confirmation by the comparison of chemical-electrochemical experimental methods
