Magnesium hydroxide is a major component of the alkaline scale formed in thermal desalination processes. This work shows that this scaling can be inhibited using low molar mass poly(acrylic acid) with hydrophobic end-groups, with a higher degree of hydrophobicity giving optimum inhibition than was previously observed for calcium carbonate and calcium oxalate scales, giving insight towards the design of improved scale-inhibitors for thermal desalination plants.
