Sorption density of OP on the surface of minerals generally decreases with increasing pH of the system, crystallinity of minerals, and relative molecular mass of OP. OPs may generally form inner-sphere complexes (hydrogen bonding interactions also plays a role in some cases) on the surfaces of minerals, and surface complexes can even transform to
