In the title compound, C(12)H(12)N(2)O(2)S, the aromatic rings are oriented at a dihedral angle of 79.48 (4)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered rings with envelope conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π Contacts between the benzene rings, [centroid-centroid distance = 4.211 (3) Å] ma...

Introduction: The presence of antibiotics due to toxicity and sustainability as well as organic compounds as a combination of hard biodegradable wastewater is an undesirable issue in many industries. The aim of this study was to evaluate the efficiency of dissolved air flotation process for aniline and penicillin G removal from aqueous solutions. Methods: This was an empirical-lab study to w...

This study is focused on removing toxic aniline from aqueous solutions using advanced oxidation process by UV/ peroxy disulfate. In this study, the effect of various parameters including pH (3-9), the level of radiation (ultraviolet 30 watt lamp, number 2-5), peroxy disulfate dose (0.02 – 0.08 mol/l) and the initial concentration (20 – 100 mg/l) at different contact times (10 – 60 min) on the e...

In this study, powder activated carbon (PAC) and magnetic nanoparticles of iron (III) oxide were used for synthesis of Fe3O4-activated carbon magnetic nanoparticles (AC-Fe3O4 MNPs) as an adsorbent for the removal of aniline. The characteristics of adsorbent were evaluated by SEM, TEM, XRD and BET. Also, the impact of different parameters such as pH, contact time, adsorbent dosage, aniline initi...

OBJECTIVE To report two cases of methemoglobinemia induced by inhaled nitrobenzene and dermally absorbed aniline. METHODS We have evaluated a 37-year-old male worker exposed to nitrobenzene by inhalation while conducting maintenance job of mononitrobenzene pump and a 25-year-old male worker exposed dermally to aniline while unloading. RESULTS The first case is a 37-year-old male exposed to ...

Polyaniline is a conductive polymer with distinctive optical and electrical properties. Its enzymatic synthesis is an environmentally friendly alternative to the use of harsh oxidants and extremely acidic conditions. 7D5L, a high-redox potential laccase developed in our lab, is the biocatalyst of choice for the synthesis of green polyaniline (emeraldine salt) due to its superior ability to oxid...

In the context of removal biochemical oxygen demand (BOD5) from food and beverages production wastewaters, this paper reports capabilities SBA-15 modified with (3-aminopropyl)-triethoxysilane (S-APTES) N-[3-(trimethoxysilyl)propyl]aniline (S-Aniline) in glucose, fructose sucrose at very high concentrations (350,000 mg/L for 350,000 170,000 sucrose), i.e. sugars most widely used as sweeteners be...

In the title compound, C(13)H(10)N(2)O(2), a Schiff base derivative, the dihedral angle between the two aromatic rings is 31.58 (3)°. The C=N double bond is essentially coplanar with the nitro-phenyl ring. The torsion angle of the imine double bond is 175.97 (13)°, indicating that the C=N double bond is in a trans configuration. The crystal structure is stabilized by C-H⋯O contacts and π-π inte...
