General description

Diethylenetriaminepentakis(methylphosphonic acid) (DTPMP) is a multidentate chelating agent. Hydrogen peroxide oxidation of DTPMP is reported. DTPMP, a phosphonate, is commonly used as crystallization inhibitors.

Application

Diethylenetriaminepentakis(methylphosphonic acid) solution is suitable for use in a study to investigate the dynamics and kinetics of sodium sulfate crystallization in the presence of various organophosphonic acids. It may be employed as ligand for the characterization of Ce3+ complexes by luminescence spectroscopy.

Acute toxicity of four relatively new chelating agents and their equimolar manganese and cadmium complexes was studied. The chelating agents studied were gluconic acid (GA), beta-alaninediacetic acid (ADA), diethylenetriaminepentakismethylenephosphonic acid (DTPMP), and nitrilotriacetic acid (NTA). Three common bioassays, namely Daphnia

The hemolytic toxicity of tributyllead (TBL) and triphenyllead (TPhL) chlorides and its prevention by dithiotreitol (DTT), diethylenetriaminepentamethylenephosphonic acid pentasodium (PMP) and sodium disulfide (Na2S) was studied. It was found that both TBL and TPhL efficiently hemolyzed pig erythrocytes when used
