The synthesis of hydrophobically-modified polymeric flocculants is also challenging due to issues associated with the insolubility of hydrophobic monomers in water. 50 This drawback could therefore complicate the synthesis process. In addition, hydrophobically-modified polymers are less soluble in water compared to the conventional polymeric
