“…This is attributed to the reduced level of randomness at the interface between the sorbent and sorbate during the dye biosorption onto the biosorbent active sites [35]. Similar negative values of ΔS° were obtained for biosorption of MB onto leaf residues of Thymus numidicus [16] and safranin O dye onto Cymopolia barbata biomass [78].…”

“…This is because the aforementioned materials are inexpensive, widely available, and have extremely high dye biosorption and reusability potentials [15]. For example, several biosorbents including Thymus numidicus leaves [16], raw cassava stems [17], walnut shell powder [18], Brazilian berry seeds [19], and corn cob [20] have reportedly been studied for the potential removal of methylene blue from aqueous solution.…”

The batch adsorptive sequestration of methylene blue from an aqueous solution using unripe Roystonea regia fruit pericarp biomass was investigated in this study. The characteristic nature of the biosorbent was studied using various analytical instruments including Fourier Transform Infra-red spectrophotometer, Scanning Electron Microscope, Energy Dispersive X-ray, X-ray diffractometer, and the Brunauer-Emmett Teller. The adsorption study was perfomed at different experimental conditions including pH, contact time, initial dye concentration, temperature, agitation speed, and biosobent dose. From the results of this study, the optimum biosorption of MB was achieved at 120 min contact time, pH 10, room temperature (298 K), 150 rpm agitation speed and dosage of 100 mg/150 mL dye solution. With 132.30 mgg-1 maximum sorption capacity, the Langmuir isotherm best describes the biosorption equilibrium data. At all initial concentrations, the biosorption kinetics of methylene blue onto the biosorbent fitted best to the pseudo-second order kinetics model, with R2 values ≥ 0.999 and qcal being similar to the qexp. The kinetics study also showed the involvement of intra-particle diffusion in the rate-determining step; although not as the sole limiting step of the sorption process. The results of the thermodynamics study showed the high feasibility, spontaneity, and exothermic nature of the biosorption of methylene blue onto the biosorbent. This study concludes that Roystnea regia fruit pericarp would make an economically viable and renewable biosorbent for practical eco-friendly sequestration of MB dye from wastewaters.

“…In this research direction, there are a number of recently reported batch experimental laboratory results in the successful removal of aqueous phase MB dye by various cost-effective and efficient biomass or other solid waste-based adsorbents. These include but are not limited to pine leaves [3], pine needle biomass [12], white pine sawdust [13], leaf residues of Thymus numidicus, Origanum glandulosum, and Spindus mukorossi [14], pine cones and pine leaves [15], pea waste [16], banana peel and avocado seed [17], sugarcane-saw dust composite [18], sugarcane bagasse, peanut hull, and orange peel [19], cashew nut shell [4], raw and modified plumeria alba (White frangiparm) [1], raw kaolin [20], kaolin [21], natural clay [22], and kaolinite [23]. Readers are encouraged to go through the review articles by Adegoke and Bello [2], Boakye et al, 2022 [6], and Afroza and Sen [24], where a large number of agricultural solid waste-based adsorbents, clay minerals, and industrial solid waste-based adsorbents are tabulated for the removal of aqueous phase dyes and other pollutants.…”

In this laboratory batch adsorption study, the raw pine tree leaf biomass solid waste adsorbent material was used for the removal of methylene blue (MB) dye from water at different physicochemical process conditions. The characteristics of adsorbents were determined for particle size, surface area, the existence of functional group identification, and the morphology of the adsorbent surface. The adsorption was performed at different process conditions, which include solution pH, dye concentrations, adsorbent doses, and temperature, respectively. In this study, it was found that MB dye adsorption increased with increases in solution pH and adsorbate MB dye concentration but decreased with adsorbent doses and temperature at fixed process conditions. The Langmuir isotherm model was best fitted with the experimental equilibrium data, with a higher linear regression coefficient (R2) value of 99.9% among the two widely used Langmuir and Freundlich adsorption isotherm model equations. The maximum Langmuir monolayer adsorption capacity of raw pine leaf was found to be 36.88 mg/g, which was comparable with other reported adsorbent capacities towards methylene blue (MB) dye adsorption. The value of the separation factor, RL, from the Langmuir isotherm model equation gives an indication of favorable adsorption. Thermodynamic parameters such as standard Gibbs free energy change (ΔG0), standard enthalpy change (ΔH0), and standard entropy change (ΔS0) indicated that the methylene blue (MB) dye adsorption by pine tree leaf biomass was spontaneous and exothermic in nature and that the mechanism of adsorption was mainly physical adsorption. Finally, limitations and future studies are also discussed here. The outcome of this batch adsorption study may result in the valorization of locally available large pine tree leaf residue waste, which could be used in water purification.
