<i>Myristica fragrans</i> Shells as Potential Low Cost Bio-Adsorbent for the Efficient Removal of Rose Bengal from Aqueous Solution: Characteristic and Kinetic Study

In the present study, the Myristica fragrans shells (MFS) was used as low-cost bio adsorbent for the removal of Rose Bengal (RB) dye from aqueous solutions. The characteristics of MFS powder were studied before and after adsorption using different techniques such as Fourier transform Infrared spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA), BET and BJH surface area analysis, Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). Batch adsorption was adopted to evaluate the effect of various parameters on the removal of RB such as; time of contact (5–75 min), initial dye concentration (10–50 mg L–1), adsorbent dose (0.1–1.7 g L–1) and pH (3–12). The results revealed that the coverage of MFS surface by RB molecules involved the formation of ester bond (esterification), and the pore diameter decreased from 190.55 to 2.43 nm when adsorption of RB onto MFS surface occurred. Experimental adsorption data were modelled using isotherm models including Langmuir, Freundlich, and Temkin. Temkin isotherm demonstrated to be the best isothermal model, and the results indicate that the adsorption of Rose Bengal on MFS surface follows pseudo second-order kinetics model. The adsorption of dye at different pH media showed that the esterification process was more preferred in acidic solution.

“…In textile manufacturing, the dyeing step is the most substantial process in terms of time, added value, and technical complexity (Huynh and Chien, 2018). This step includes the dyeing itself and the washing to remove the non-fiber dye, releasing 10 to 15% into wastewater (Jayanthy et al, 2014). Kharat (2015), reported cases where the indiscriminate discharge of textile effluents has affected soil and groundwater quality.…”

“…In this way, some synthetic dyes are soil pollutants that concern researchers due to the toxic nature and adverse effect on life forms (Smaranda et al, 2017). Regarding this, azo dyes are carcinogenic in nature (Jayanthy et al, 2014;Stagnaro et al, 2015). This dye typology is characterized by having one or more double nitrogen bonds (-N = N-) (Jayanthy et al, 2014), and approximately half of the world's industrial production belongs to this class (Stagnaro et al, 2015).…”

Wastewater from textile industries is loaded with synthetic dyes. These effluents are often not adequately treated, affecting the soil and groundwater quality and leading to environmental contamination. The Agreste mesoregion of the state of Pernambuco is home to one of the largest textile centers in Brazil. This work therefore aims to study the behavior of Remazol Black B (RB5) dye in subsurface mediums in this region. The kinetics and isotherm sorption experiments allowed an evaluation of RB5 retention capacity in two layers of alluvial soil of the dry riverbed of the Capibaribe Basin. The maximum sorption rate was 81.81 mg kg-1 and 21.7 mg kg-1 for the loamy sand and sand layers, respectively. The Pseudo-second order kinetic model described more appropriately the sorption kinetics for both soils. The isotherms behavior was nonlinear, and Freundlich model was the most suitable to describe this process for both soils, presenting KF values of 8.6407 L kg-1 for loamy sand and 0.1868 L kg-1 for sand. The isotherm parameters confirm a more significant interaction of RB5 with the loamy sand layer than with the sand layer, indicating lower leaching in the first layer, which is less mobile for RB5 contamination. Furthermore, the different sorption rates for both soils indicate the importance of studying the soil as a heterogeneous profile.

“…Various industries such as cosmetics manufacturing industries, dyeing industries, paper and paperboard manufacturing industries, and textile industries produce colored effluents ( Jayanthy et al, 2014 ). Dyes have complex molecular structures and are often toxic, carcinogenic (production of amine groups in anaerobic decomposition), non-biodegradable and sustainable ( Asgher et al, 2013 , Helmes et al, 1984 ).…”

The effect of granular coral limestone and Leca as adsorbents for removing Acid Cyanine 5R (AC5R) from aqueous solution was studied. The optimum pH and adsorbent particles size in both adsorbents were determined to be 3 and 297 μm, respectively. The optimum dosages of coral limestone and granular Leca were 0.150 and 0.145 g/mg of dye, respectively. Also, results have shown that the adsorption efficiency by both coral limestone and Leca increased with the decreasing adsorbent particles size. Moreover, under similar conditions, the maximum removal efficiency by granular coral limestone and Leca was 94% and 88%, respectively. The results revealed that the performance of granular coral limestone was better in AC5R removal than that of Leca granulated under such condition. In total, granular coral limestone and Leca act as suitable adsorbents for removing dye pollutants from an aqueous solution.
