TL;DR: In this paper, the characteristics of organoclays as sorbents for neutral organic contaminants (NOCs) in aqueous systems containing multiple solutes were evaluated by measuring the sorption of trichloroethylene on hexadecyltrimethylammonium (HDTMA) exchanged illite and smectite in the absence and presence of carbon tetrachloride, nitrobenzene and ethyl ether.

TL;DR: In this paper, a peroxi-coagulation method for wastewater treatment is presented, where the aniline and its intermediates are oxidized mainly by reaction with OH, which is produced from Fenton's reaction between electrogenerated H 2 O 2 and Fe 2+.
Abstract: A novel electrochemical method for wastewater treatment, called peroxi-coagulation, is presented in this paper. Degradation of aniline in acidic solution of pH- 3 has been studied using this method. Electrolyses were performe in an undivided cell with an Fe anode and a carbon-polytetrafluoroethylene 02-fed cathode which continuously electrogen-erates H 2 O 2 . The anode dissolves yielding Fe 2+ and Fe 3+ . This last ion gives a precipitate of hydrated Fe(III) oxide. Aniline and its intermediates are oxidized mainly by reaction with OH, which is produced from Fenton's reaction between electrogenerated H 2 O 2 and Fe 2+ . Competitive coagulation of oxidation products with the hydrated Fe(III) oxide precipitate also occurs. These processes allow a fast and almost complete total organic carbon removal for aniline solutions in short-time electrolyses. The method has higher decontamination power than other electrochemical treatments tested, such as electrocoagulation with a graphite cathode, and electro-Fenton and photoelectro-Fenton with a Pt anode. Benzoquinone, nitrobenzene, NH 4 + , and NO 3 - were detected in electrolyzed solutions. Precipitates contain coagulated organics with a major proportion of nitrogen-containing compounds. A pathway for aniline peroxi-coagulation involving these species is proposed.

TL;DR: In this article, the degradation of nitrobenzene (NB) by modified Fenton reaction at near neutral pH conditions using Fe II -glutamate complex as a source of Fe 2+.
Abstract: We examined the degradation of nitrobenzene (NB) by modified Fenton reaction at near neutral pH conditions using Fe II –glutamate complex as a source of Fe 2+ . The reaction was conducted using 0.04 mM (5 mg L −1 ) of NB in presence of 65 mM H 2 O 2 at room temperature. Complex concentrations of 5, 10, 15 and 20 mM (Fe 2+ = 0.81, 1.62, 2.43 and 3.23 mM) were assayed and showed effective rates of NB degradation with t 1/2 values of 17, 6.2, 4.8 and 1.85 min, respectively. In the pH range 5–7 the complex activity is pH-dependent, and the optimal pH was 6.3. The degradation was monitored by solid-phase microextraction in combination with GC analysis. The rate of degradation recorded at near neutral pH in presence of 20 mM of Fe-complex was equal to that obtained in presence of Fe 2+ (2.5 mM) at pH 2.7. Glutamate complexes formed with Cu 2+ or Co 2+ did not show the improved degradation observed in case of Fe–glutamate. Furthermore, the introduction of the chelating agent as a free ion into the reaction medium containing Fe 2+ did not improve the degradation of NB at neutral pH conditions.
