Abstract

A facile and simple method has been developed for the condensation of 1,2-diaminobenzenes with alpha-bromoketones to form quinoxalines with good yields using cetyltrimethyl ammonium bromide (CTAB) in aqueous media. The efficiency of this reaction was demonstrated by the compatibility with nitro, methyl, methoxy, fluoro chloro bromo and furanyl groups. The important features of the methodology are broad substrate scope, simple workup, and no requirement for metal catalysts.

Enhanced Cr(VI) adsorption using chemically modified dormant Aspergillus niger spores: Process and mechanisms

Binqiao Ren, Yu Jin, Luyang Zhao, Chongwei Cui, Xiaoxiao Song

Summary: Adsorption materials based on Aspergillus niger spores were chemically modified with CTAB to enhance the biosorption capacity of chromic acid ions. The secondary amine (-NH-) played a crucial role in the reduction adsorption process, reducing hexavalent chromium by transferring electrons to unoccupied orbit of Cr(VI). The fungal biological adsorbent showed promising potential for repeated adsorption and desorption of hexavalent chromium without significant decrease.

Preconcentration and Determination of Palladium by Solvent-Free Microextraction and Flame Atomic Absorption Spectrometry (FAAS) in Environmental Samples

Zekeriyya Bahadir, Gokhan Kultur, Murat Yazar, Demet Cakir, Celal Duran

Summary: An alternative methodology based on the combination of microextraction with flame atomic absorption spectrometry (FAAS) is reported for the determination of Pd2+ in environmental samples. The method involves the use of CTAB as a surfactant and precipitating agent to form a complex with Pd2+ in the presence of iodide. The results show that this solvent-free microextraction is simple and sensitive for the preconcentration and determination of micrograms per liter of Pd2+ in various environmental samples.

Influence of particle size and surfactants on uniformity and quantity of silicon carbide particles in electrodeposited nickel-silicon carbide coatings

Kan Hong-min, Meng Yuan-yuan, Ramana G. Reddy

Summary: The size of silicon carbide particles affects the uniformity and quantity of silicon carbide particles in nickel-silicon carbide composite coatings, with 40 nm particles being more effective than 500 nm particles. In terms of surfactants, anionic surfactant SDS produced better dispersion of 40 nm silicon carbide particles compared to cationic surfactant CTAB.

Determination of thermodynamic parameters for cloud point extraction of Arsenazo-III and Magdala Red dyes using mixed micelles: An essential requirement for high performance

Sk Ameer Khan, D. Radha Krishna, P. Shyamala

Summary: A simple and low-cost method for the extraction and preconcentration of ARS-III and MR dyes was developed using efficient cloud point extraction with mixed micelles of TX-114 and CTAB. The method showed good recoveries, with thermodynamic quantifies indicating spontaneity and endothermicity. Temperature, surfactant concentration, and dye concentration all affected the thermodynamic quantifies, with recoveries ranging from 90.02-101.03% for ARS-III and 86.07-99.46% for MR dyes.

Patricia Viana Rodrigues, Fernanda Arruda Nogueira Gomes Silva, Fernanda Veronesi Marinho Pontes, Carla Napoli Barbato, Viviane Gomes Teixeira, Tainara Cristina de Assis, Vitor Schwenck Brandao, Luiz Carlos Bertolino

Summary: This research evaluated the application of palygorskite to reduce glyphosate contamination in synthetic effluent. The study showed that organo-palygorskite, treated with wet granulometric classification and wet magnetic separation, had an increased cation exchange capacity and surface area. The 1.0% organo-palygorskite adsorbed about 86% of glyphosate. Thus, organo-palygorskite can be a potential adsorbent for remediating effluents containing the toxic herbicide glyphosate.

DSC studies of the influence of gamma irradiation on the structural properties of the complexes formed with cetyl-trimethyl-ammonium bromide

Krystyna Ciesla, Hubert Rahier

Summary: The effect of irradiation on further transformations of potato starch in the starch-CTAB-water system was studied using DSC, revealing structural changes and decreased symmetry in complexes formed using irradiated starch compared to non-irradiated starch. Thermal treatment induced deterioration of the complex structure in irradiated samples, while non-irradiated starch showed no significant modifications. Changes in complex structure were detected in granular starch samples when doses in the range of 2-30 kGy were applied, with 5 kGy causing easily noticeable modifications.
