An automatic microgravimetric screening system based on piezoelectric detection and the use of acidic stannous chloride as reductant was developed for the fast detection and determination of total mercury in water. Reduced mercury is detected as an amalgam by using a gold-coated piezoelectric crystal, the sensor subsequently being regenerated by passing it through a peroxydisulfate solution. Th...
atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...
Present work investigates the capability of oxidative treatment process in the presence of nano silver doped on silicate particles for decolorization of a widely used azo dye, C.I. Direct Blue 129 (DB129) in water samples. Solutions with initial concentration of 20 mgL-1 of dye, within the range of generic concentration in textile wastewaters, were treated under ambient conditions of initial pH...
Abstract Nonradical oxidation based on peroxydisulfate (PDS) activation has attracted increasing attention for selective degradation of organic pollutants. Herein, topological defects were introduced into biochar (BC) via removing N atoms in N-doped BC (NBC) an attempt to improve the nonradical catalytic performance. Compared pristine and NBC, introduction could achieve up 36.6- 8.7-times activ...
Chemical oxidative polymerization of aniline in dilute aqueous acids using an ammonium peroxydisulfate oxidant proceeds via the intermediacy of large, colorless aggregates that act as ‘seeds’ in orchestrating the overall morphology of the product polyaniline. Observed for the first time by continuously monitoring the polymerization by static and dynamic light-scattering (LS) measurements, these...
Magnetic CuFe2O4 powder obtained by sol−gel method and coupled photocatalysis was used to activate peroxydisulfate for tetracycline (TC) removal. A scanning electron microscope, X−ray diffraction Raman spectroscopy FT−TR were characterize the catalysts. The degradation efficiency stability of TC highest under neutral conditions. rate reached 91.1% within 90 min. removal total organic carbon rea...
