“…The novelty and originality of this study compared to the previous studies [ 16 , [20] , [21] , [22] , [23] , [24] , [25] , [26] ] is the use of the MMTF models to scrutinize the kinetics and decolorization mechanisms of the RBBR dye mediated by different fungi. This may provide better understanding on the mass transfer of dye molecules by employing fungal mycelium for use in designing the further engineered bioremediation systems.…”

“…Reflections on the history of the mass transfer factor (MTF) models were firstly developed by Fulazzaky [ 16 , 20 ] to describe the adsorption of single solute from aqueous solution onto granular activated carbon (GAC) processed in a hydrodynamic column. Using the MTF models permits us to describe the mass transfer kinetics of Cd(II) ions adsorption by titania polyvinylalcohol-alginate beads from aqueous solution in a batch reactor [ 21 ]. The MTF models were then modified to extend their applicability for describing the adsorption of multi-solute from surface water onto GAC applied to a hydrodynamic column [ 22 ].…”

“…At the initial As(V) concentration 400 μg L − 1 and pH 4.0 after 120 h, As(V) removal rate was equal to 94%. In the paper by Fulazzaky et al [ 29 ], it was proved that due to the valence electrons associated with the O–H functional groups of titania PVA-alginate beads, Cd(II) ions can be precipitated in the form of Cd(0). The alginate-TiO 2 sorbent was also used for adsorption and removal of cationic (Methylene Blue, MB) and anionic (Methyl Orange, MO) dyes from waters and wastewaters [ 30 ].…”

The novel organic-inorganic biohybrid composite adsorbent was synthesized based on nanosized silica-titania modified with alginate within the development of effective adsorbent for heavy metal ions. Effects of metal species Cu(II), Zn(II), Cd(II), and Pb(II); concentrations; pH; temperature; and adsorption onto titania-coated silica (ST20) initial or modified by sodium alginate (ST20-ALG) were studied. The equilibrium and kinetic data of metal ions adsorption were analyzed using Langmuir and Freundlich adsorption models and kinetic models: pseudo first order, pseudo second order, intraparticle kinetic model, and Elovich. The maximum sorption capacities observed were higher for the ST20-ALG composite compared to the initial ST20 oxide for all studied metal ions, namely their values for ST20-ALG were 22.44 mg g− 1 for Cu(II) adsorption, 19.95 mg g− 1 for Zn(II), 18.85 mg g− 1 for Cd(II), and 32.49 mg g− 1 for Pb(II). Structure and properties of initial silica-titania ST20 and modified by sodium alginate ST20-ALG adsorbents were analyzed using nitrogen adsorption/desorption isotherms, ATR-FTIR, SEM-EDS, and pHpzc techniques.

In textile industries, residual dyes and heavy metals are usually released into environment via wastewater effluent. Because of their negative effects not only to environment but also to human health, these contaminants are required to be removed from water environment. To achieve the effective adsorption of dye and heavy metal, the adsorption mechanism needs to be understood clearly. In this study, the complexity of adsorption of Remazol brilliant blue R (RBBR), methyl orange (MO), copper (Cu) ions, and iron (Fe) ions onto numerous natural adsorbents was analyzed using the modified mass transfer factor model (MMTF). The secondary adsorption data were collected from various sources. The study found that MMTF has a superior adaptability for describing the mechanism of the adsorption of dyes and heavy metals both in solely and in multi solute.
