TL;DR
This paper introduces carboxyl carbon quantum dots as an environmentally friendly and highly effective scale inhibitor, demonstrating complete inhibition of calcium sulfate and barium sulfate at low dosages below 80°C.
Contribution
It is the first to demonstrate the high scale inhibition efficiency of CCQDs, highlighting their potential as eco-friendly scale inhibitors for calcium and barium sulfate.
Findings
Achieved 100% anti-scaling efficiency at low CCQD concentrations
Effective for calcium sulfate and barium sulfate
Operates below 80°C with static tests
Abstract
In this work, we demonstrate high inhibition efficiency of carboxyl carbon quantum dots (CCQDs) for the first time. The as-prepared CCQDs have excellent scale inhibition performance for calcium sulfate and barium sulfate. With static test of scale inhibition within temperature below 80 degrees, the anti-scaling efficiency can reach 100 % with low additions of CCQDs.
