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.


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.

Four different textile preparation effluents were simulated to examine the applicability of the hydrogen peroxide/ultraviolet-C (H2O2/UV-C) advanced oxidation process for the treatment of real textile preparation (desizing, scouring and bleaching) wastewater bearing the non-ionic surfactant nonyl phenol decaethoxylate (NP-10). In...

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...

Catalytic oxidation of various chelating agents in aqueous solutions, namely: diethylenetriaminepentakis(methylphosphonic acid) (DTPMP); diethylenediaminepentaacetic acid (DTPA); ethylenediamine tetraacetic acid (EDTA); nitrilotriacetic acid (NTA); and beta-alaninediacetic acid (beta-ADA) was studied. Hydrogen peroxide was used as oxidising agent in combination with five...

The distribution and elimination of 99Tcm-complexes with methylene-diphosphonate (MDP) and with the calcium salt of diethylene-triamine-penta(methylene phosphonate) (DTPMP) were compared in rats. Both compounds exhibited high bone uptake and long-term retention of radioactivity in the skeleton. No significant accumulation of...
