“…Effect of ultrasonic power. The adsorption process induced by the sonic wave is well known to accelerate the physical dispersion process 29 due to the phenomenon of acoustic cavitation by a liquid, which leads to the mass transfer improvement in the system and thus increases the dye sorption strength. The study of the ultrasonic power revealed that q e increases with an increase in the ultrasonic power from 0.1 to 0.4 kW (Fig.…”

We report a novel method for the synthesis of 3-mercaptopropyl trimethoxysilane-modified hydroxyapatite (FHAP-SH) derived from fish-scale residues by using ultrasound irradiation. Scanning electron microscopy, transmission electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy were used for the FHAP-SH characterization. Then, the organic dye adsorption on the FHAP-SH was monitored through an ultrasound process. After the dye removal optimization, significant improvements were observed in the maximum adsorption capacities for Congo Red (CR, 500 mg g−1), Coomassie Brilliant Blue G 250 (CB, 235 mg g−1), and Malachite Green (MG, 625 mg g−1). The adsorption behaviors of these dyes were fitted by using the Langmuir isotherm model with a high coefficient of determination values ranging from 0.9985 to 0.9969. The adsorption of the three dyes onto FHAP-SH was an endothermic process based on the adsorption thermodynamics model, while the adsorption kinetics analysis of the dyes presented a good alignment with the pseudo-second-order kinetics. The FHAP-SH exhibits a remarkably high adsorption capacity, is inexpensive, and fulfills the ecofriendly requirements of dye wastewater treatment, especially in the textile industry.

“…Each sample was spiked with three concentrations (5.0, 50.0, and 100.0 μM) of the standard solution of CN – and with three concentrations (5.0, 50.0, and 250.0 μM) of the standard solution of [Fe(CN) 6 ] 3– . The relative percentage recoveries were calculated as follows where C found , C real , and C added are the concentration of an analyte after addition of a known amount of a standard in the real sample, the concentration of an analyte in the real sample, and the concentration of a known amount of a standard that was spiked in the real sample, respectively. The recoveries were expressed as the mean values of three independent determinations.…”

This study aims to use graphene quantum dots (GQDs) as a fluorescence switching sensor (turn on–off) for the simultaneous detection of cyanide (CN–) and ferricyanide [Fe(CN)6]3– in wastewater samples. The GQDs were synthesized by pyrolyzing solid citric acid. The intrinsic blue color of the solution was observed under ultraviolet irradiation. The fluorescence spectrum was maximized at both excitation and emission wavelengths of 370 and 460 nm, respectively. The fluorescence intensity of GQDs decorated with Hg2+ (turn-off mode as the starting baseline) could be selectively turned on in the presence of CN– and once back to turn-off mode by [Fe(CN)6]3–. The fluorescence switching properties were used to develop a fluorescence turn-on–off sensor that could be used to detect trace amounts of CN– and [Fe(CN)6]3– in water samples. For highly sensitive detection under optimum conditions (Britton–Robinson buffer solution in the pH range of 8.0–9.0, linearity ranges of 5.0–15.0 μM (R 2 = 0.9976) and 10.0–50.0 μM (R 2 = 0.9994), respectively, and detection limits of 3.10 and 9.48 μM, respectively), good recoveries in the ranges of 85.89–112.66% and 84.88–113.92% for CN– and [Fe(CN)6]3–, respectively, were recorded. The developed methods were successfully used for the simultaneous and selective detection of CN– and [Fe(CN)6]3– in wastewater samples obtained from local municipal water reservoirs.

“…Subsequently, with the optimized Au/Ag ratio of 1:2, the Au amount was controlled for the optimal LDI-MS. The npAu-TNW was fabricated with Au (Ag) layers of 1 (2), 2 (4), 5 (10), and 10 (20) nm and the npAu-TNW with Au (Ag) amount of 5 (10) nm showed the highest LDI-MS performance (Figure S6B, Supporting Information). When the thickness of the Au (Ag) layer decreased to 1 (2) and 2 (4) nm, the resulting npAu-TNW had insufficient surface area for the efficient LDI-MS.…”

The physicochemical properties of nanostructured substrates significantly impact laser desorption/ionization mass spectrometry (LDI-MS) performance. Fundamental understanding of the substrate properties can provide insights into the design and development of an efficient LDI matrix. Herein, a hybrid matrix of nanoporous Au-modified TiO 2 nanowires (npAu-TNW) is developed to achieve enhanced LDI-MS performance. Its origin is investigated based on hybrid matrix properties including photo-thermal conversion and electronic band structure. Notably, further improvement is obtained in the npAu-TNW than in the pristine TNW and non-porous Au nanoisland-modified TNW (Au-TNW) hybrid, which is attributed to the laser-induced surface restructuring/ melting phenomenon. Noticeable surface restructuring/melting occurs in the npAu by laser exposure through efficient photo-thermal conversion of the highly porous npAu. At this instant of npAu structural changes, internal energy transfer from the npAu to the adsorbed analyte is promoted, which facilitates desorption. Moreover, strain is developed in situ in the TNW adjacent to the restructuring npAu, which distorts the TNW lattice. The strain development reduces recombination rates of charge carriers by introducing shallow trap levels in the bandgap, which enhances the ionization process. Ultimately, the high LDI-MS performance based on the npAu-TNW hybrid matrix is demonstrated by analyzing neurotransmitter.
