Adsorption of methylene blue from aqueous solution on pyrolyzed petrified sediment

Effect of temperature on the sorption and desorption of perfluorooctane sulfonate on humic acid

“…This is consistent with the result of Johnson et al (2007). Sorption of ionic organic contaminant Methylene Blue on pyrolyzed petrified sediment has obtained ΔH 0 values ranged between 14 and 18.5 kJ/mol, and ΔS 0 values ranged between 52.8 and 67 J/(mol·K) (Aroguz et al, 2008), similar to the anionic PFOS sorption to humic acid. The high positive values of standard entropy changes, 69.5 J/(mol·K), was found in this study, suggesting that the sorption was entropy driven process.…”

Applications of Brazilian pine-fruit shell in natural and carbonized forms as adsorbents to removal of methylene blue from aqueous solutions—Kinetic and equilibrium study

“…As can be seen in Table 6 [6,16,20,[52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71], the PW and C-PW adsorbents employed in this work presented very high adsorption capacities for MB adsorption when compared with several adsorbents. From 28 different adsorbents, only seven adsorbents presented higher sorption capacity than PW; and just one presented higher sorption capacity than C-PW [6,16,20,[52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71]. These outstanding sorption capacities for MB adsorption places C-PW as one of the best adsorbents for MB removal from aqueous solutions and PW as an intermediate adsorbent in relation to the adsorption capacity for MB removal from aqueous solution.…”
