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.

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 ...

The technique of using biochar-based catalysts in persulfate activation is a promising alternative to remov emerging and refractory pollutants (e.g., tetracycline-) wastewater. However, the situation biochars derived from waste pulp/paper mill sludge still unclear. (SBC300, SBC500, SBC700) were obtained characterized at pyrolysis temperatures 300, 500, 700 °C. Tetracycline degradation peroxydis...

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 ...

Effects of respirable aerosols of sulfuric acid, ammonium sulfate, sodium sulfite, and ammonium persulfate on lungs of rats are reviewed. The literature regarding interactions between ozone or nitrogen dioxide and acidic aerosols (ammonium sulfate, sulfuric acid) is discussed. An unexpected interaction between nitrogen dioxide and sodium chloride aerosol is also discussed. An attempt is made to...

Pyrolysis of lemon stalks at 850 °C under a limited oxygen atmosphere yields highly active and selective biochar for the activation persulfate ion oxidation sulfamethoxazole (SMX). The mainly consists C O atoms, with Ca K being most abundant minerals. It has moderate specific surface area 154 m2 g−1 carbonate species, probably in form calcium carbonate. Complete degradation 0.5 mg L−1 SMX can b...
