The concentration of peroxides in atmosphere in Beijing and Guangzho u was measured by using the HPLC post-column derivatization system.

The effect of sodium dodecyl sulfate (SDS) on the activity and conformation of soybean peroxidase (SBP) was studied by the measurement of activity, far-UV circular dichroism spectra, electronic absorption spectra, and fluorescence spectra at different pH values and 30 ℃ .

soybean peroxidase(SBP) belongs to class III of plant peroxidase superfamily that includes the classical peroxidase, namely horseradish peroxidase (HRP).

Effect of chemical degradation of peroxide on polypropylene's crystallinity;

Study on high density polyethylene crosslinked with peroxide;

Effect of peroxide content in acrylonitrile on yellowness of polyacrylonitrile fiber;

Using polypropylene as material,peroxidate as prodegradant and adopting single factor alternate method the polypropylene coated resin for braided bag coating with melt flow rate 2～3 g/min was sythensized.

In this paper, the composites of glass fiber coated with peroxidate solution and polypropylene(PP) were obstained.

Determination of concentration of peroxides in atmosphere by spectrophotometry;

Study on the Yield of Peroxides from Atmospheric Reaction of CH_3C(O)CH═CH_2 with O_3 by Long Path FTIR;

In both MAC and MVK ozonolysis reactions in water, formaldehyde, methylglyoxal, hydrogen peroxides (H_2O_2) and hydroxymethyl hydroperoxides (HMHP) were found; and their yields (%) were determined: 49.
