While application of conventional removal processes like chemical precipitation, ion exchange, commercial activated carbon adsorption, etc often become cost-prohibitive, the adsorption of MB by abundantly available green pea peel (GPP: Pisum sativum) derived and acid-treated carbon (GPP-AC) has proved to be a cost-attractive option in the present study. The physicochemical and morphological characteristics of GPP-AC were examined with the help of XRD, BET surface area, SEM, and Fourier transform infrared spectrophotometry ((FT-IR) analysis. The influences of such adsorption parameters as initial dye concentration, pH, contact time, adsorbent dosage, agitation speed, particle size, and temperature were evaluated and optimized. The equilibrium contact time for maximum adsorption of MB on to GPPAC was found to be 7 h. The equilibrium data of the adsorption process were modeled by using the Langmuir, Freundlich, Temkin, and Dubinin-Raduskevich (D-R) isotherms. However, the adsorption equilibrium data were best described by the Langmuir Isotherm model, with a maximum adsorption capacity of 163.94 mg MB/g GPPAC at 30A degrees C.</p>10aAdsorption10aDubinin-raduskevich10aFreundlich10agreen peas peels10aIsotherms10aLangmuir10aMethylene blue10aTemkin1 aDod, Ramesh1 aBanerjee, Goutam1 aSaini, S.  uhttps://library.ncl.res.in/content/adsorption-methylene-blue-using-green-pea-peels-pisum-sativum-cost-effective-option-dye-001973nas a2200229   4500008004100000022001400041245012700055210006900182260005700251300001400308490000700322520111300329653001501442653001401457653001301471653001901484653005601503100001601559700002101575700001801596856012901614       2015                        eng d  a1618-954X00aRemoval of methylene blue (MB) dye from water environment by processed Jowar Stalk [Sorghum bicolor (L.)

Moench] on suitable heat and acid treatment. The physico-chemical and morphological characteristics of processed carbon of JS origin were studied using X-ray diffraction, scanning electron microscopy, Brunauer, Emmett and Teller surface area, and Fourier transform infrared spectrophotometry analyses. The batch studies revealed optimum values of adsorption parameters such as pH, adsorbent dosage, agitation speed, grain size, temperature, and contact time as 7, 1.5 g l(-1), 200 rpm, finer than 75 A mu m, 30 A degrees C, and 7 h, respectively. The adsorption isotherm data were best described by Langmuir isotherm model with a maximum adsorption capacity of 176.05 mg MB g(-1) JS activated carbon at 30 A degrees C, which is higher than that available with adsorbents used by past researchers. In terms of cost-effectiveness, JS carbon shows its superiority over commercially available carbon.</p>10aAdsorption10aIsotherms10akinetics10aMethylene blue10aProcessed Jowar Stalk [Sorghum bicolor (L.)
