The application of the matrix solid-phase dispersion (MSPD) process as sample treatment in connection with the electrochemical detection is studied for the first time. For this purpose, a novel methodology is introduced for the extraction of propham and maleic hydrazide herbicides from potatoes ...
This study aims the removal of a carbamate herbicide, propham, from aqueous solution by direct electrochemical advanced oxidation process using a boron-doped diamond (BDD) anode. This electrode produces large quantities of hydroxyl radicals from oxidation of water, which leads to the oxidative d...
Publisher SummaryThis chapter provides the basic synthesis paths routes for the manufacture of propham, with a listing of the main raw materials and intermediates used in the synthesis of propham. Propham is commercially known as Birgin and it belongs to the carbamate group.
Electro-Fenton process has been widely used in the treatment of organic pollutants lately. Its oxidation efficiency mainly depends on the electrode materials. In this study, boron doped diamond (BDD), carbon sponge (CS) and platinum (Pt) electrodes were used at four different configurations as a...
The removal of a carbamate herbicide, propham, from aqueous solution has been carried out by the electro-Fenton process. Hydroxyl radical, a strong oxidizing agent, was generated catalytically and used for the oxidation of propham aqueous solutions. The degradation kinetics of propham evidenced ...
This paper reports on ours study on the electrochemical oxidation of the herbicide propham (Pro) on glassy carbon electrode modified with multi-walled carbon nanotubes (GCE/MWCNTs). This is a first report on this topic. We studied the effect of the supporting electrolyte, pH, frequency, amplitud...
In this study, a double-step modified carbon paste electrode (CPE) was prepared for the voltammetric determination of propham (PRO). In the first step, modification of CPE was performed by incorporating 12.5% fumed silica (FS) into paste structure to obtain CPE-12.5FS. In the second step, CPE-12...
In this study, an electrochemical sensor was developed for the determination of propham (PRO) in potato, human urine and river water samples based on the over-oxidized poly(thiophene) modified pencil graphite [PG/p(Thp)-Ox] electrode. Adsorptive stripping differential pulse voltammetry was used ...
Recently reported diphenylamine (DPA) in conjugation with biphenyl based D-π acceptor-D type mixed valence compounds (MV) have paved the way to design and development of new set of mixed valence compounds. In the present work, heteroaromatic π-acceptors (bi-furan, bi-thiophene and bi-pyrrole) ...
We fabricated a novel core–shell-type microsphere-based electrorheological (ER) composite material using poly(diphenylamine) (PDPA) as an electro-responsive coating layer onto polystyrene (PS) particles of controlled size and morphology. The coating of the core particle with a semiconducting sh...
Available online A series of diphenylamine (DPA)-containing triarylamine-based D-D-π-A organic fluorescence dyes were designed under the guidance of theoretical calculations and then synthesized (cyanoacrylic acid, methylene malononitrile or isophorone served as the electron acceptor while ethy...
Three star-shaped compounds based on a truxene core (FS11, FS12 and FS13) were prepared. The truxene core is incorporating with asymmetric diphenylamines, including one phenyl of diphenylamine substituted by methoxy group and the other phenyl substituted by tolyl, fluorophenyl and phenylethynyl ...
A novel diphenylamine/spiro[fluorene-9,9′-xanthene] (SFX) hybrid (SFX27DPA) was constructed successfully by incorporating diphenylamine into SFX via Pd-catalyzed CN cross-coupling to ingeniously develop state-of-the-art models of solution-processible small molecule host for uncovering the struc...
Four donor-acceptor-donor (D-A-D’) unsymmetrical squaraines (USQs) with different molecular skeletons (XZ-type and YZ-type), containing diphenylamine group with/without methoxy substituent were synthesized as donor materials in bulk-heterojunction (BHJ) organic photovoltaics (OPVs). The introdu...
Synchronously switchable electrochromic/electrofluorochromic polymers have captured intense attention in the field of displays and sensors. However, most of the emerged materials could not exhibit satisfactory switching performances, especially the slow response speed. In this work, a novel fluo...
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used drugs in the world but some NSAIDs such as diclofenac and tolfenamic acid display levels of cytotoxicity, an effect which has been attributed to the presence of diphenylamine contained in their structures. A novel series of d...
The novel antimony(III) halide complexes with the bi-dentate substituted dithiooxamide ligand, N,N-dicyclohexyldithiooxamide (HDTOA) of formulae {[SbBr3(HDTOA)1.5]}n (1) and {[SbI3(HDTOA)1.5].C6H6}n (2), were prepared by reacting antimony(III) bromide or antimony(III) iodide with HDTOA in 1:1 mo...
The reaction of antimony(III) chloride with the bidentate substituted dithiooxamide ligand, N,N-dicyclohexyldithiooxamide (HDTOA), in 1:1 molar ratio, leads to the formation of the polymeric complex {[SbCl3(HDTOA)1.5]}n (1). The complex was characterized by FT-IR spectroscopy, 1H,13C NMR spectro...
In the search for novel efficient chiral resolving agents, we have studied the diastereoselective acylation of 3,4-dihydro-3-methyl-2H-[1,4]benzoxazine and 7,8-difluoro-3,4-dihydro-3-methyl-2H-[1,4]benzoxazine with acyl chlorides of 2-phenoxy carboxylic acids (2-phenoxypropionic, 2-phenoxyisoval...
