Surface modification of calcium carbonate with phosphonic acids

Wassim El Malti, Danielle Laurencin, Gilles Guerrero, Mark E. Smithb and P. Hubert Mutin Abstract The surface of precipitated calcite particles was modified by reaction with phosphonic acids(phenylphosphonic acid and dodecylphosphonic acid) in organic solvents, tetrahydrofuran (THF) andethanol. The reaction kinetics and adsorption isotherms were determined. Under appropriateconditions, dense phosphonate monolayers were deposited at the […]
