Comparison of silver and palladium nanoparticles loaded on activated carbon for efficient removal of Methylene blue: Kinetic and isotherm study of removal process

Rapid Green Synthesis of Silver Nanoparticles (AgNPs) Using (Prunus persica) Plants extract: Exploring its Antimicrobial and Catalytic Activities

“…Synthesis of nanoparticles by green approach is emerging field because of its various advantages over the other process like nontoxic, ecofriendly and low cost. AgNPs showed promising applications in different engineering fields such as electrical, catalytic properties, water, drug delivery and biomedical engineering because of its high surface to volume ratio [13][14][15][16]. Green approach also involved many microorganisms like bacteria, fungi, and yeasts for the synthesis of nanoparticles.…”

Synthesis and characterization of SnO2/(NH4)2‐SnCl6 nanocomposites loaded on activated carbon and its application for adsorption of methylene Blue and Orange G

“…This results is explained by the fact that following adsorption of first layer of charged dyes on adsorbent and formation of semi-capacitor, hinder form more layer adsorption via repulsive force among layer [43] The effect of isotherm shape has been discussed with a view to predict whether an adsorption system is favorable or unfavorable which in Langmuir isotherm represent by R L value to separation factor or equilibrium parameter. [44] The i.e., whether the process is unfavorable (R L > 1), or linear (R L = 1), or favorable (0 < R L < 1), or irreversible (R L = 0) and as results show R L values were in the range of 0 < R L < 1 (Table 4) which support high efficiency of this model for [48] Activated Carbon (walnut shells) MB 315.0 1440 [49] CuO-Nanoparticles Loaded on Activated Carbon MB 10.55 15 [50] PDA microspheres MB 90.70 100 [51] MWCNTs filled with Fe 2 O 3 particles MB 42.90 60 [52] Ag-Nanoparticles Loaded on Activated Carbon MB 71.43 15 [21] Humic Acid-coated Fe 3 O 4 -NP (HA-Fe 3 O 4 ) MB 93.08 27 [53] Activated Carbon of Thespesia Populnea Pods OG 9.120 180 [54] Bagasse Fly Ash OG 18.79 240 [10] explanation of data in single (MB and OG) and binary system (MB-OG) on the SnO 2 /(NH 4 ) 2 -SnCl 6 -NCs-AC. Freundlich parameters (K F and n) indicate whether the nature of sorption is either favorable or unfavorable and accordingly 1 < n < 10 imply favorable sorption and its value closer to 1 suggest more uniform adsorbent.…”

“…adsorbents unsaturated and easily binding with other atoms are good modifier which expensively improve performance of adsorption system. [21] Sn this regard, application of tin based nanostructure as boarder line atoms seems able to bind various reactants and pollutants. On the other hand, present adsorbent, i.e.…”

Adsorption Capability of Cationic Dyes (Methylene Blue and Crystal Violet) onto Poly-γ-glutamic Acid

“…Table 5 summarizes the reported adsorption capacities of various MB and CV adsorbents in the literature. [50][51][52][53][54][55][56] The data show that PGA has higher adsorption capacities than many of the other reported adsorbents for MB and CV. Therefore, it can be concluded that PGA is an efficient adsorbent for removal of MB and CV from aqueous solution.…”
