“…It makes sense that as the amount of time increases, more dye molecules have a chance to adsorb on the surface of the HMNP. This result is in agreement with other studies 40 . Initial dye concentration is the primary factor affecting the effectiveness of dye adsorption and significantly impacting the absorption rate.…”

Discharging untreated dye-containing wastewater gives rise to environmental pollution. The present study investigated the removal efficiency and adsorption mechanism of Acid Red 18 (AR18) utilizing hexadecyl-trimethyl ammonium chloride (HDTMA.Cl) modified Nano-pumice (HMNP), which is a novel adsorbent for AR18 removal. The HDTMA.Cl is characterized by XRD, XRF, FESEM, TEM, BET and FTIR analysis. pH, contact time, initial concentration of dye and adsorbent dose were the four different parameters for investigating their effects on the adsorption process. Response surface methodology-central composite design was used to model and improve the study to reduce expenses and the number of experiments. According to the findings, at the ideal conditions (pH = 4.5, sorbent dosage = 2.375 g/l, AR18 concentration = 25 mg/l, and contact time = 70 min), the maximum removal effectiveness was 99%. The Langmuir (R2 = 0.996) and pseudo-second-order (R2 = 0.999) models were obeyed by the adsorption isotherm and kinetic, respectively. The nature of HMNP was discovered to be spontaneous, and thermodynamic investigations revealed that the AR18 adsorption process is endothermic. By tracking the adsorption capacity of the adsorbent for five cycles under ideal conditions, the reusability of HMNP was examined, which showed a reduction in HMNP's adsorption effectiveness from 99 to 85% after five consecutive recycles.

This work aims to prepare a novel phosphate-embedded silica nanoparticles (P@SiO2) nanocomposite as an effective adsorbent through a hydrothermal route. Firstly, a mixed solution of sodium silicate and sodium phosphate was passed through a strong acidic resin to convert it into hydrogen form. After that, the resultant solution was hydrothermally treated to yield P@SiO2 nanocomposite. Using kinetic studies, methylene blue (MB) dye was selected to study the removal behavior of the P@SiO2 nanocomposite. The obtained composite was characterized using several advanced techniques. The experimental results showed rapid kinetic adsorption where the equilibrium was reached within 100 s, and the pseudo-second-order fitted well with experimental data. Moreover, according to Langmuir, one gram of P@SiO2 nanocomposite can remove 76.92 mg of the methylene blue dye. The thermodynamic studies showed that the adsorption process was spontaneous, exothermic, and ordered at the solid/solution interface. Finally, the results indicated that the presence of NaCl did not impact the adsorption behavior of MB dye. Due to the significant efficiency and promising properties of the prepared P@SiO2 nanocomposite, it could be used as an effective adsorbent material to remove various cationic forms of pollutants from aqueous solutions in future works.

Neste trabalho, dois xerogéis de sílica foram preparados pelo processo sol-gel usando uma solução aquosa ácida e uma solução aquosa básica como catalisadores para cada material, nomeados como SiO2-A e SiO2-B, respectivamente. Corantes, como o azul de metileno (AM), são contaminantes comuns presentes em águas residuais de indústrias têxteis e a busca ou aperfeiçoamento de processos capazes de reduzir esses danos via retenção destes poluentes, é de extrema importância. Esses xerogéis foram usados como adsorventes para a remoção de AM de soluções aquosas. Espectroscopia de absorção nas regiões do Ultra-Violeta e do visível foi usada para monitorar o processo de adsorção. A porosidade e a morfologia destes xerogéis foram estudadas usando isotermas de adsorção e de dessorção de N2 e Microscopia Eletrônica de Varredura (MEV), respectivamente. Os dados experimentais mostraram que a adsorção de AM é maior em pH 9,0, para ambos os xerogéis, com uma alta performance para o xerogel SiO2-B. Estes resultados foram melhor ajustados ao modelo da isoterma de Langmuir, atingindo valores de massa máxima de adsorção de 50,6 mg g-1 e 8,24 mg g-1 de AM para SiO2-B e SiO2-A, respectivamente. As imagens de MEV mostraram que o xerogel SiO2-A possui uma superfície lisa, enquanto que SiO2-B tem uma morfologia rugosa e com aglomerados. Os dados de porosidade mostraram que esses xerogéis são mesoporosos. Nossos experimentos demonstraram que os xerogéis SiO2-A e SiO2-B poderiam ser usados em aplicações ambientais para a remoção de poluentes da água tais como corantes.
