beyond substituted p-phenylenediamine antioxidants: prevalence of,substituted para-phenylenediamine (ppd) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. however, there is a paucity of research on the environmental occurrences of their transformation products. in this study, we revealed the co-occurrence of six ppd-derived quinones (ppd-qs) along with eight.

screening p-phenylenediamine antioxidants, their transformation,recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.
- What does DMPD stand for?
- N,N -Dimethyl- p -phenylenediamine dihydrochloride (DMPD) 1 is a compound that is normally used to measure the antioxidant potentials of fruit juices and other natural products. In the presence of ferric iron, it gets converted to DMPD + radicals, which are scavenged by antioxidant molecules present in test samples .
- What are analytical protocols involving DPPH radicals?
- Analytical protocols involving DPPH radical are varied. Drawing up an analytical protocol seems to be a simple procedure. The radical is freely soluble in methanol or ethanol, solvents that also dissolve most of the antioxidants which are of technological or functional interest.
- What is modified DMPD method?
- The modified DMPD method proposed by us measures with great accuracy the oxidant potential of plasma, using the oxidizing effect of plasma to oxidize DMPD into producing a stable pink color that obeys the Beer–Lambert law at 505 nm. The method is fast and reproducible.
- What is DPPH scavenging mechanism by an antioxidant?
- DPPH scavenging mechanisms by an antioxidant (AH). The DPPH test is a simple technique and requires only a Vis spectrophotometer or an electronic paramagnetic resonance (EPR) spectrometer. However, DPPH • is not a natural radical but the mechanism of reaction with antioxidants is similar to that with peroxyl radicals ROO • .
