“…NACs are broadly classi ed into two major categories i.e., phenolic and non-phenolic compounds. Among diverse phenolic and non-phenolic NACs, 2,4,6-trinitrophenol (TNP) shows an exceptionally high toxicity [4]. It is utilized in different industries such as dyes, drugs, polymers, rocket fuel, matchbox, electric battery and recrackers etc.…”

An amine-decorated zirconium-based metal–organic framework (MOF, coded as UiO-66-NH2) with rod shaped morphology has been solvothermally synthesized using low-cost and easily available 2-aminoterephthalic acid as an organic linker. The crystallinity of the synthesized MOF material has been confirmed by sharp PXRD diffraction pattern. Photoluminescent studies showed that the UiO-66-NH2 features a strong fluorescent behaviour when dispersed in water, which could be used as a highly selective and sensitive sensor for detection of trace amount of 2,4,6-trinitrophenol (TNP), even in coexistence with other potentially competitive nitroaromatic analytes. High value of Stern-Volmer quenching constant Ksv (1.106 x 105 M-1), photoluminescent quenching efficiency (97.8%) and lower detection limit (0.95 μM/217ng mL-1) ascertained extraordinary sensitivity of developed UiO-66-NH2 for TNP. Density functional theory (DFT) calculations and electrostatic interactions (i.e. ionic interaction, H-bonding and π-π interaction) indicated that electron and energy transfer processes play a key role in the turn-off quenching response of UiO-66-NH2 sensor towards TNP.

“…The CPE can be improved by changing the micellization of the surfactant, and increasing the solubility of micelles, temperature and additive content [ 13 ]. According to Gao et al [ 9 ] and Bhatt et al [ 14 ], few studies have reported the use of ionic liquids (ILs) as an additive with non-ionic surfactants in CPE [ 9 , 14 ]. In this study, 1-butyl-3-methylimidazolium bromide (BMIMBr), an IL, and tetrasodium of N , N -bis(carboxymethyl) glutamic acid (GLDA), a chelating agent, are used as additives.…”

Cloud point extraction (CPE) is a separation and preconcentration of non-ionic surfactant from one liquid phase to another. In this study, Sylgard 309 and three different types of additives for CPE, namely CPE-Sylgard, CPE-Sylgard-BMIMBr and CPE-Sylgard-GLDA, are investigated to extract methylphenol from water samples. The methylphenols are well separated by reversed-phase high-performance liquid chromatography (HPLC) with isocratic elution of acetonitrile : water; 60 : 40 (v/v) and detection at 260 nm. The optimized parameters for the effect of salt, surfactant, temperature, time of extraction, pH, interference study and the performance of different additives on methylphenol extraction are investigated. CPE-Sylgard-GLDA is chosen because it gives us a high peak and good peak area compared with CPE-Sylgard and CPE-Sylgard-BMIMBr. The recovery extractions of CPE-Sylgard-GLDA are obtained in the range of 80–99% as the percentage of relative standard deviation (RSD) is less than 10. The LOD and LOQ are 0.05 ppm and 0.18 ppm, respectively. The method developed for CPE-Sylgard-GLDA coupled with HPLC is feasible for the determination of methylphenol because it is simple, effective, cheap, and produces a high percentage of recovery.

The removal of hazardous picric acid is of great importance to making healthy and drinkable water. In this research, a nanocomposite (MWCNT-EDTA-CMC) based on carboxylated multiwall carbon nanotubes (MWCNT-COOH) modified by carboxymethylcellulose (CMC) and ethylenediamintetraacetic acid (EDTA) was prepared for adsorption and removal of picric acid from aqueous solutions. MWCNT-EDTA-CMC was characterized by Fourier transform infrared (FT-IR), field-emission scanning electron microscopy (FESEM), thermal gravimetric analysis (TGA). Central composite design (CCD) was used to study the influence of pH, adsorbent dosage, and initial picric acid concentrations on the removal percentage of picric acid. At optimum conditions (pH 3.0, MWCNT-EDTA-CMC dosage 0.050 g, picric acid concentration 30 mg L À1 ), high removal efficiency (97.67%) was obtained for picric acid which was reasonably well predicted by the model. The adsorption process was demonstrated by the pseudo-second-order kinetic and Freundlich isotherm models for both adsorbents. In addition, the consumed MWCNT-EDTA-CMC could be reused up to 3th cycle of regeneration.adsorption, carbon nanotube, central composite design, desorption, picric acid 1 | INTRODUCTION 2,4,6-trinitrophenol or picric acid is one of the most acidic phenols which is an explosive material like other strongly nitrated organic compounds. [1] It has also been used in the production of explosives, medicine, dyes, fungicides, and the oxidation of metal surfaces. [2][3][4] Hence, in during these processes, it could release into the environment such as the atmosphere, water, and soil and thus, cause serious health problems for example lung, liver, and kidney damages or an allergic skin reaction since picric acid is toxic if swallowed, inhaled, or absorbed through the skin. [5][6][7] Industrially, picric acid is especially hazardous because it is volatile and slowly sublimes even at room temperature. So, the removal of picric acid from aqueous solutions has been a major focus of research and is vital.Up to now, various methods for instance, degradation, [8] oxidative destruction, [9] solvent extraction, [10] biodegradation, [11] electrochemical, [12] and adsorption [13] were applied to remove picric acid.
