A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

Macroporous polyacrylamide-grafted-chitosan scaffolds for neural tissue engineering were fabricated with varied synthetic and viscosity profiles. A novel approach and mechanism was utilized for polyacrylamide grafting onto chitosan using potassium persulfate (KPS) mediated degradation of both polymers under a thermally controlled environment. Commercially available high molecular mass polyacryl...

In this Communication, we report on the first preparation of conjugation polymer poly(2,3-diaminonaphthalene) (PDAN) microspheres via chemical oxidation polymerization of 2,3-diaminonaphthalene (DAN) monomers by ammonium persulfate (APS) at room temperature. We further demonstrate the use of PDAN microspheres as a novel quencher for fluorescence-enhanced nucleic acid detection.

Model solutions of bisphenol A (BPA) in 0.050 M Na2SO4 at pH 3.0 have been treated by the electro/Fe2+/persulfate process. The activation 5.0 mM persulfate with 0.20 Fe2+ yielded a mixture sulfate radical anion (SO4?) and OH, although quenching tests revealed prevalence former species as main oxidizing agent. In trials run an IrO2/carbon-felt cell, 98.4% degradation was achieved alongside 61.8%...

results the results showed that the pcp degradation increased with an increase in zvi dosage from 0.056 to 1.4 g/l, an increase in persulfate concentration from 2.5 to 15.0 mm/l, and an increase in zvi to ps molar ratio from 0.1 to 2.5. the optimal initial ph for pcp removal was 5.0 and the maximum removal efficiency of 70% was achieved within 120 minutes. moreover, the zvi catalyst was reused ...

Ammonium persulfate-dimethyl sulfoxide (APS-DMSO) has been developed as an efficient and new dehydrating reagent for a convenient one-pot process for the synthesis of miscellaneous cyclic imides in high yields starting from readily available primary amines and cyclic anhydrides. A plausible radical mechanism involving DMSO has been proposed. The application of this facile one-pot imide forming ...
