Adsorption of cationic dyes on Jalshakti®, super absorbent polymer and photocatalytic regeneration of the adsorbent

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.…”

Radiation preparation of PVA/CMC copolymers and their application in removal of dyes

“…Consequently, the adsorption parameters (K f and 1/n) describe on quantitative basis the adsorption process. Freundlich constant n > 1 indicates favorability of adsorption [25,26]. The adsorption rate constant, K f , represents the adsorption capacity of PVA/CMC (50/50) hydrogel.…”

Cation transfer across a hydrogel/organic phase: Effect of cation size, hydrophobicity and acid–base properties

“…Hydrogels are robust, three-dimensional, cross-linked structures that swell in water, and these materials have many potential applications [27][28][29][30][31][32][33][34][35][36][37]. These applications are closely related to the intrinsic properties of the polymeric networks [29,[31][32][33][34][35][36][37], and two main characteristics of hydrogels should be emphasized: their chemical structures and the morphology of their networks.…”

“…These applications are closely related to the intrinsic properties of the polymeric networks [29,[31][32][33][34][35][36][37], and two main characteristics of hydrogels should be emphasized: their chemical structures and the morphology of their networks. The former affects the hydrophilic/hydrophobic ratio of the gel, and consequently, its water retention and absorption capacity.…”
