Phosphonates are organophosphor compounds that contain C-PO(OH)2 and C-PO(OR)2 R alkyl and aril groups. They are water solubles but they are not dissolved in organic solvents.
Phosphonates are very good ion immobilizers and they have chelating properties. Therefore, they are used in many industrial fields.
Phosphonates, which are disintigrated by bacteria, are a good phosphor source for them. Therefore, many phosphonates cause extreme eutrophication in water.
