Development a New Carbon Nanocomposite Containing MWCNT as Adsorbent for Effective Removal of Cloxacillin

“…As well, the criterion of 1/n was obtained between 0 and 1, hence, it be able to said that the adsorbent surface is inhomogeneous (Ponnuchamy;. This point out that the Freundlich model can also be applied to expression the adsorption model of the Clox on MWCNT/CC.…”

Is the Frumkin (Fowler–Guggenheim) adsorption isotherm a two- or three-parameter equation?

“…Some authors have made the incorrect claim that the Frumkin isotherm is only valid for θ < 0.6 [49,50]. The second misconception concerns the use of the Frumkin isotherm and the Fowler-Guggenheim isotherm to fit the same isotherm data [51][52][53][54][55][56][57]. As noted above, the Frumkin isotherm is mathematically analogous to the Fowler-Guggenheim isotherm.…”

“…The D-R capacity parameter is widely used as a surrogate for Frumkin's qm to calculate θ [13][14][15][16][17][18][19][20][21]. Like the Langmuir and Freundlich isotherms, the two-parameter D-R isotherm can be easily linearized, allowing its capacity parameter to be estimated by linear regression.…”

“…Freundlich [10][11][12], and Dubinin-Radushkevich (D-R) [13][14][15][16][17][18][19][20][21] have been inserted into the linearized Frumkin isotherm to calculate θ. In particular, the D-R capacity parameter is a popular surrogate, probably owing to the fact that it was featured in a review article [22].…”

Lab-on-a-chip technologies for food safety, processing, and packaging applications: a review

“…More importance should be given to device performance, its integration in food processing lines as well as testing standards for it to become commercially available. Lab-on-a-chip devices should also be combined with strategies for valorization and agricultural and food waste for integrated technological solutions in environmental protection (Ponnuchamy et al 2020 ). Lab-on-a-chip technology has potential to play a major role in facilitating end-to-end traceability throughout the food production chain.…”
