Assessment of aqueous extract of Gypsophila aretioides for inhibitory effects on calcium carbonate formation

open access: yesGreen Processing and Synthesis, 2019
The aqueous extract of Gypsophila aretioides roots as a “green” or eco-friendly inhibitor of carbonate calcium formation was investigated. The presence of chelating factors such as polyphenol compounds and foaming agents in the plant extract was assessed.
