Materials and methods
- Study type:
- other: both direct and sensitised photolysis were studied
- Principles of method if other than guideline:
- Study of photodegradation (5-hr duration) with UV light and catalyst Mn and H2O2 (at 1%). The degradation products phosphate (PO4), ammonium (NH4) and total organic carbon (TOC) were analyzed in order to indirectly verify the cleavage efficiency of the C-P bond and C-N bond.
Also, the influence of the concentration of the catalyst Mn was tested for HDTMP. - GLP compliance:
- no

Study design
- Analytical method:
- other: spectrophotometry
- Details on sampling:
- The samples were collected after initial 10 minutes, then after 30 minutes and subsequently in an interval of 30 minutes until the end of the study (full duration 5 hours).
- Light source:
- other: lamp
- Light spectrum: wavelength in nm:
- 200
- Relative light intensity:
- 600
- Details on light source:
- 450 W lamp with wavelength from 200 to 600 nm (Heraeus Noblelight, Germany)
- Details on test conditions:
- The liquid volume of 350 ml containing phosphonates were exposed to UV light in a reactor with quartz cooling jacket and a 450 W lamp with wavelength from 200 to 600 nm. Concentrations: 100 mg/L, 0.20 mmol of HDTMP were used.
The degradation products phosphate (PO4), ammonium (NH4) and total organic carbon (TOC) were analyzed in order to indirectly verify the cleavage efficiency of the C-P bond and C-N bond.
Also, the influence of the concentration of the catalyst Mn was tested for HDTMP. 40 ml of phosphonate (100 mg/L) were treated with Mn at concentrations, 0.5%, 1%, 2%, 3%, 4%. The solutions were left continuously stirred for 24 hours and NH4 was measured after 1 h, 2 h, 4 h, 8 h and 24 h.
