“…Next, 93 full-text articles were reviewed, out of which 44 studies were eligible for the qualitative analysis according to the established inclusion criteria. The 44 papers were composed of articles containing the physicochemical and adsorption properties of ACs from the three selected biomass sources with the respective distributions: coconut shell [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], bamboo [16,[23][24][25][26][27][28][29][30][31][32][33][34] and rice husk [35][36][37][38][39][40][41][42][43][44][45][46][47][48]. The analyses were divided into two categories: (a) synthesis conditions affecting the differences in physicochemical properties of ACs and (b) effects of physicochemical properties onto MB adsorption performance.…”

This systematic literature review (SLR) describes the trend of study in activated carbons (ACs) from various biomass sources, specifically coconut shell, rice husks, and bamboo, for the adsorption of methylene blue (MB). Data acquisition and extraction from online databases were performed to review and discusses the effects of the synthesis parameters (i.e., carbonization temperature and holding time) to the physicochemical properties of the synthesized ACs (i.e., surface area, pore volume) and the effects of physicochemical properties to the MD adsorption. The SLR shows that the carbonization temperatures significantly affect the surface area and pore volume of ACs synthesized from coconut shells and rice husks, while ACs synthesized from bamboo were significantly influenced by the holding time. MB adsorption by ACs from all three biomasses increased with the increasing surface area and pore volume. This SLR could be a guideline to the synthesis ACs from biomass for the removal of dye in wastewater.

“…One question might be pondering over one's head is that can wastewater treatment be carried out by incurring minimal cost for the same? The answer to this question lies in the nature itself, that is, by making use of natural materials to adsorb the contaminants present in the wastewater which in turn will reduce the likelihood of the impairment of the quality of ground water which is mainly used for irrigation (6). Adsorption is basically the process in which contaminants present in one medium or phase tend to condense and concentrate on the surface of other face, wherein the material being concentrated is adsorbate and the adsorbing solid is called as adsorbent (32).…”

From the inception of the Coronavirus pandemic for the more than a year, it has now become exigent that the water supplies and wastewater be treated at its fullest efficiency as their nexus is quite ubiquitous in this domestic society. To design a robust wastewater treatment incurs a hefty cost, so the need of the hour is to resort towards treatment techniques which incurs minimal cost and adsorption techniques are one of them. Adsorption is a process where contaminants or compound in one phase gets attached or condensed to other phase, finally removing them. Adsorption by using activated carbon is a prominent method to remove the contaminants from water and wastewater remarkably, but still many researches shows the same as expensive and therefore, low-cost adsorbents extracted naturally is a best and cheapest alternative to remove the same. Numerous researches showed the potency of such low-cost adsorbents in removing heavy metals, dyes, etc. from the wastewater, but there is no literature available pertinent to the removal of parameters viz. COD, BOD, etc. from the wastewater. The present research aims to study the alteration of functional parameters viz. adsorbent dosages and pH in the removal of COD by comparing its efficiency supplemented with batch adsorption studies on the low-cost adsorbents viz. neem leaves and coconut husk.

This study shows that geographically marked wheat hull, named Siyez, rice hull Sarı Kılçık, and Taşköprü Garlic stalk were used as agricultural waste to potential adsorbent materials for removing methylene blue from aqueous solution. Experimental data were evaluated in both equilibrium batch process and kinetic studies. In addition, the factors that affect the adsorption capacities, such as pH solutions, methylene blue concentration, contact time, and temperatures, were also investigated. Obtained data were subject to two constant adsorption models of Langmuir, Freundlich, Temkin, and Dubinin−Radushkevich. The kinetic models (pseudo-first-order, pseudo-second-order, intra-particle diffusion and film diffusion) and thermodynamic parameters were evaluated. The adsorption isotherms, characterized by an excellent fit with the Langmuir model (R2 = 0.99) across all adsorbents, underscore the prevalence of monolayer adsorption of methylene blue, in contrast to the Freundlich equation. Adsorption kinetics of the methylene blue onto the adsorbents followed pseudo-second-order kinetic model. According to high regression coefficient (R2) and minimal values of nonlinear error functions like RMSE; the maximum monolayer adsorption capacities of wheat hull, rice hull and garlic stalk were found to be 62.50 (mg/g), 54.94 (mg/g), and 370.37 (mg/g), respectively. The results indicated that these proposed adsorbents could be low-cost and effective adsorbents for water purification and have adsorption capacity as much as comparable with the literature. In batch equilibrium studies, the adsorption of methylene blue dye onto the wheat hull, rice hull, and garlic stalk exhibited a significant correlation with temperature, contact time, and initial concentration of methylene blue dye and Adaptive Neuro-Fuzzy Inference System algorithm for forecasting overall the system parameter well fitted with these findings with the accuracy of outputs (R2 about 0.99 for each). Consequently, the thermodynamic analysis revealed that the adsorption process takes place in bulk diffusion by liquid phase mass transfer and occurred spontaneously with endothermically except garlic stalk. Adsorption thermodynamic studies show that the adsorption of methylene blue onto the garlic stalk was spontaneous and exothermic. Graphical Abstract
