A simple, rapid and sensitive spectrophotometric method for determination of Lisinopril (LS) in both pure form pharmaceutical preparations has been reported. The adapted technique based on utilization 4-aminonaphthalene-1-sulfonic acid as a Chromogenic reagent through an oxidative coupling reaction with Potassium Peroxydisulfate (oxidation agent) acidic medium to green dye soluble product absor...

ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals...

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...

The photo-oxidative decolorization of Direct Red 23 (DR23), a textile dye which is suspected to be carcinogenic was investigated using peroxydisulfate activated by UV irradiation and heat in a batch photo-reactor at experimental conditions. A very simple analytical method, direct UV–vis spectrophotometric detection, was utilized for the progress of photo-oxidative decolorization of dye in aqueo...

A bifunctional probe (PTC-Tb) which acts as not only a well-defined and stable electrochemical redox molecule but also as a highly efficient co-reactant of an electrochemiluminescent oxygen-peroxydisulfate system was firstly synthesized and applied to the construction of dual-response aptasensors for thrombin detection.

This paper reviews the recent literature on the title reactions and updates a 1988 review.

Monodisperse silver nanoparticles were synthesized by a new developed method via reaction of AgNO3 and oleic acid with the addition of a trace amount of Fe3+ ions. Emulsion polymerization at room temperature was employed to prepare a core-shell silver nanoparticle with controllable particle size. N,N'-methylenebisacrylamide (MBA) and potassium peroxydisulfate (KPS) were used as a crosslinker, a...

To describe and predict the leaching of Ag, Cu Sn from waste photovoltaic modules with an electrochemical-assisted process kinetic investigations were performed. In this process, peroxydisulfate is generated sulfuric acid to oxidize metals. It was found that under reaction conditions peroxymonosulfate formed as well has a major contribution process. For autocatalytic decomposition reagents dete...

The present research involves effectual parameters on Cefixime trihydrate removal from aqueous solutions. Antibiotics are the main contributions in pharmaceutical waste; their presence causes major concern. The extensive utilization of antibiotics in aquaculture and prescriptions has led to the cultivation of various antibiotic-resistant bacteria and genes in wastewater. The UV-LED/S2O82- pr...

Drought is one of the most important stress factors limiting the seed industry and crop production. Present study was undertaken to create novel drought-resistant pelleted seeds using the combined materials with superabsorbent polymer, poly(2-acrylamide-2-methyl propane sulfonic acid) (PAMPS) hydrogel, and drought resistance agent, salicylic acid (SA). The optimized PAMPS hydrogel was obtained ...
