“…The maximum adsorption capacity (q max ) of CR, CB, and MG was 500, 235, and 625 mg g −1 , respectively. The q max values of CR, CB, and MG removal by FHAP-SH were compared to those of the other previously reported adsorbents [31][32][33][34][35][36][37][38][39][40][41] . As shown in Table 2, the q max values in this work were significantly higher than those previously reported for other adsorbents.…”

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.

“…MOF materials exhibit unique advantages in the high adsorption capacity, effective selectivity and rapid adsorption rate of organic pollutants owing to high specific surface area, adjustable pore structure (size, shape and modified functional groups) and designable skeleton structure [12–17] . Based on previous research theories, ionic MOF materials can adsorb dyes with opposite charges to the pores/channels but dyes that possess same charges will be rejected through ion‐exchange and electrostatic interactions [18–36] . Liu et al [26] reported an anionic framework material with functional imide groups can efficiently adsorb Basic Red 9 and Basic Violet 14 by electrostatic interaction and ion‐exchange.…”

We reported a PtS-type anionic metal organic framework (MOF) with uncoordinated carboxyl-groups and suitable pore size, (InOF). InOF displays highdensity electronegative functional sites about 12 negative sites in one unit cell, which exhibits its potential application for selective removal cationic dye from effluents. In fact, the InOF crystals can rapidly and selectively capture methylene blue dyes from effluents based on the charge-effect and size-effect at room temperature.

“…It has been demonstrated that ultrasound irradiation can promote chemical transformations, improve yields and purity of the products, and shorten the reaction time at mild condition [20]. In this work, seed addition was fixed to 0.5 wt.% and different ultrasonic times on the structure of SSZ-13 were investigated.…”

Because of its unique eight-membered ring pore structure and the arrangement of cations in its structure, the SSZ-13 molecular sieve has a higher affinity for CO2 than other gases, meaning it has attracted more attention than other porous materials for CO2 adsorption. However, the expensive template and long preparation time limits the industrial production of SSZ-13. In this work, a hollow structure was successfully introduced into the nanosized SSZ-13 molecular sieve with ultrasonic treatment. The effects of the amount of seed added and the ultrasonic time on the structure were investigated. When the amount of seed added was 0.5 wt.% and the ultrasonic time was 60 min, the sample showed a hollow cubic crystal with a diameter of about 50 nm. The specific surface area reached 791.50 m2/g, and the mesoporous ratio was 66.3%. The samples were tested for CO2 adsorption performance at 298 K. It was found that the hollow sample prepared in this work has higher CO2 adsorption capacity compared with the SSZ-13 zeolite prepared with conventional methods. When the adsorption pressure was 0.27 bar, the adsorption amount reached 2.53 mmol/g. The hollow SSZ-13 molecular sieve reached a CO2 adsorption capacity of 4.24 mmol/g at 1 bar.
