This paper describes voltammetric method for determination of TDZ via its reduction at a 1,4-benzoquinone modified carbon paste electrode (1,4-BQMCPE).
Among those peroxidases, myeloperoxidase is found with particularly high concentrations, which activates hydroquinone to 1,4-benzoquinone (1,4-BQ), a more reactive species of benzene [6].

1) corresponds to arthropods that cluster in part because they utilize quinones--most notably 1,4-benzoquinone, 2-methyl-1,4-benzoquinone, and 2-methoxy-3-methyl-l,4-benzoquinone (Fig.
A small amount, 300 ppm, of 1,4-benzoquinone (Fluka) was used as an inhibitor to control the cure kinetics.
1,4-Benzoquinone decreased the quantum yield of HPD photobleaching at all concentrations studied (from 0.001 up to 0.25 mM) (Table 7).
The oxidizing agent Ce(IV)[SiO.sub.2] is prepared by coating silica gel with ceric ammonium nitrate and is used to oxidize hydroquinones to their corresponding 1,4-benzoquinone. Analytical results from [H-NMR.sub.1] spectroscopy, including detection limits, will be presented to demonstrate that heterogeneous oxidation only occurs when Ce(IV) is supported on the surface of silica gel, and is not promoted by the individual components of this solid-supported reagent either se parately or when physically mixed.
