- •
Sodium hexametaphosphate (NaHMP) can adsorb on kaolinite Al
OH terminated (001) surface easily.- •
The oxygen atoms of hexametaphosphate form strong hydrogen bonds with the hydrogen atoms of kaolinite Al
OH surface.- •
The electrostatic force is the main interaction between NaHMP and Al
OH surface.- •
The linear hexaphosphate −[PO3]m− chains adsorb stably than −[HPO3]m− chains.
