“…The reason is that increase in dye concentration facilitates higher interaction between MB and JS. Further, higher initial dye concentration facilitates to overcome the resistance to mass transfer of MB between the adsorbent and aqueous phase [18,22,41]. The study indicated that under the studied levels of time, there was no significant difference among treatments after 60 min.…”

“…RSM was explored to derive an empirical model for optimum response, i.e., % dye removal [42]. In most of the reported literature, effect of individual process parameters has been investigated [3,22,25,26,[42][43][44]. These studies required lots of experimental samples, along with long experimental time and overall high cost and, further no information on interaction effect of the factors on adsorption process.…”

“…Among all available methods, adsorption is most accepted and widely explored. Though activated carbon is a very good adsorbent, but owing to high cost of production, researchers have explored various locally available natural resources like rice husk , saw dust of oak , jute processing waste , peel of banana and orange , wheat shells , untreated beech sawdust , coir pith carbon , papaya leaf powder , carrot stem powder , cashew nut shell , Annona squmosa seed , tobacco stem biomass , rice husk activated carbon , Cupressus sempervirens cones , pine cone biomass , water hyacinth , tea waste , biomass flyash , palmarosa wastes based alginate beads , Nigella sativa seeds , etc. In present study, jute ( Corchorus olitorius ) stick (JS) stick have been used as a novel adsorbent to remove a cationic dye, methylene blue (MB) from aqueous solution.…”

In this study, jute stick (JS), the underexplored by‐product of jute (Corchorus olitorius) cultivation system, has been used as a novel low‐cost adsorbent to remove methylene blue (MB), a cationic dye, from an aqueous medium. Box–Behnken design matrix and response surface methodology (RSM) have been used to evaluate the effect of four important process factors namely, solution pH (3–11), adsorbent dose (0.5–5 g L−1), initial dye concentration (50–200 mg L−1), and time (60–180 min). JS was characterized by physico‐chemical parameters, pHzpc (zero‐point charge), FTIR for the functional groups and SEM–EDX for surface morphology. The direct and interaction effects of adsorption parameters were studied. The optimum values of pH, dose, initial concentration, and time for maximum % dye removal were 10.27, 5 (g L−1), 200 (mg L−1), and 66.06 min. Regeneration and recycling studies were also carried out. The present study indicated that JS, a bio‐waste of jute cultivation system, can be effectively utilized as an adsorbent to treat MB contaminated aqueous medium/ wastewater before environmental disposal. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

“…Reactive dyes are the most problematic compared to other forms of dye [21]. Papaya leaf has been used as adsorbent for the removal of a basic dye (methylene blue) [22] , but no study has ever been conducted to use papaya leaf as adsorbent for the removal of reactive dye. The purpose of this work was to study the coagulationflocculation process in combination with the adsorption method for the removal of Reactive Red 3BS from aqueous solution.…”

Attempts were made to investigate the effectiveness of a combined process of coagulation-flocculation and adsorption for the removal of reactive dye (Reactive Red 3BS) from aqueous solution. The effluent obtained from the coagulation-flocculation process was the raw solution for the second step of the coupling process, i.e. adsorption. The coagulation-flocculation process and the adsorption method were also studied individually. The optimum pH and the optimum dosages of alum and calcium oxide for the coagulation-flocculation process were determined. Aluminium sulphate (alum), calcium oxide and papaya leaf were used as the coagulant, coagulant aid and adsorbent, respectively. Complete dye removal from raw solution having a concentration of 100 mg L -1 could be achieved by using 300 mg L -1 of alum, 80 mg L -1 of calcium oxide and 0.20 g of papaya leaf adsorbent. Adsorption tests showed that papaya leaf could be used as a potential adsorbent for the removal of Reactive Red 3BS from aqueous solution. The maximum sorption capacities of papaya leaf in the case of sorption from pretreated solution and pure solution were 50.23 mg g -1 and 21 mg g -1 , respectively. The combined coagulation-flocculation/adsorption process may be a useful treatment technique for wastewater contaminated with reactive dye.

“…The maximum adsorption capacity of MB was found to be 285.7 mg/g at 25°C. Batch sorption experiments were carried out by Mukhlish et al (2012) to investigate the potentiality of papaya leaf powder (PLP) for the removal of MB from aqueous solutions. Papaya leaf adsorbent showed to better remove MB in basic medium.…”
