Therefore, simple short wave UV exposure may be an effective means to degrade DEHP within and on PVC plastic and the addition of H 2O 2is only beneficial if additional degradation of PVC is needed. VC2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40649.

Evaluating UV/H2O2 exposure as a DEHP degradation treatment

However, FTIR results reveal that the introduction of H2O2 reduces bulk DEHP degradation and leads to competing radical chain scission reactions with PVC. Therefore, simple short wave UV exposure may be an effective means to degrade DEHP within and on PVC plastic and the addition of H2O2 is only beneficial if additional degradation of PVC is

Evaluating UV/H2O2 exposure as a DEHP degradation treatment

Abstract Millions of tons of plasticized poly(vinyl chloride) (PVC) materials are disposed every year. A biologically sustainable and green method for removal of

The Oxidation of Di-(2-Ethylhexyl) Phthalate (DEHP) in

The present study aims to evaluate the oxidation ofDEHP by UV/H2O2 and the degradation kineticsremoving PAEs. The degradation rate of DEHP wascompared between UV/H2O2and direct UV photol-ysis. Moreover, the photochemical degradation mech-anism was evaluated to analyze the intermediates andtotal organic carbon (TOC).

Evaluating UV/H2O2 exposure as a DEHP degradation treatment

Here we compare the surface and bulk structural changes of DEHP‐plasticized PVC after two treatments intended to degrade bis‐2‐ethylhexyl phthalate (DEHP) in PVC plastic: short wave (254 nm) UV with and without the addition of 35 wt % H 2 O 2. Sum frequency generation vibrational spectroscopy (SFG) reveals the addition of aqueous H 2 O 2

Study on the biodegradation of di-ethyl hexyl phthalate (DEHP

inorganic salt medium (DEHP concentration 450 mg/L) for 60 h. The samples were taken every 6 h from the 0 h. Three parallel samples were taken each time to determine the residual amount of DEHP. The degradation curve of DEHP by JZ1 under the best degradation conditions was drawn with time as abscissa and DEHP concentration as ordinate.
