Table 1 Scale inhibition performances and biodegradabilities of common coordination groups[9,10,11]
Functional groupScale inhibition performanceBiodegradable
—COOHHydrophilic groups, improve the anti-scale of CaCO3 and CaSO4, can convert amorphously deposited Zn(OH)2 into Zn2+, and improve the zinc stabilization ability[9]Easy to biodegrade
—SO3HStrong polar hydrophilic group, improve the anti-scale of Ca3(PO4)2 and CaCO3, improve the dispersion performance of Fe2O3, have threshold effect, can reduce the amount of scale inhibitorHard to biodegrade
—OHHydrophobic group, improve the anti-scale of Ca3(PO4)2 and CaCO3, can convert amorphously deposited Zn(OH)2 into Zn2+Easy to biodegrade

—NH2,

—CONH2

Polar hydrophilic groups, improve the anti-scale of CaCO3, and increase the dispersion ability of Fe2O3[10], and turning calcite into thermodynamically unstable vaterite

Easy to biodegrade,

do not promote microbial growth in water

—PO3H2Hydrophilic groups, improve the anti-scale of CaCO3[11]Hard to biodegrade
—CHOCarbonyl group could participate the Mannich reaction due to its active chemical property, and the carbonyl group containing the lone pair of electrons can be chelated with metal ionsEasy to biodegrade
