“…The values of R L indicated that the essential characteristic of the Langmuir isotherm type was either unfavorable (R L > 1), linear (R L ¼ 1), favorable (0 < R L < 1), or irreversible (R L ¼ 0). 47,48 As shown in Fig. S7, † the R L values of the adsorption of AO7 and DB15 on Fe 3 O 4 -pDMC were smaller than 0.15, showing that the adsorption of anionic dyes on Fe 3 O 4 -pDMC was a favorable process.…”

“…In general, the adsorption contact time is an important step in understanding how the EBT (adsorbate) approaches the adsorbent surface. Quick removal of adsorbed species is initially facilitated by a large surface area, but the limited number of active sites on the adsorbate's surfaces causes it to become saturated rapidly [22].…”

This research assessed the use of agricultural waste as an adsorbent materials to remove dyes from aqueous solutions as a cheap and environmentally friendly adsorbent. Activated carbon (AC) was produced from corn residue and characterized to be nanosized with crystal size 25.83 nm from XRD data and grain size 76.68 nm from FESEM. An anionic dye represent as Eriochrome Black (EBT) used to removed from agueous solution with several adsorption studies were undertaken at varied temperatures, pH levels and adsorbent doses, EBT color molecules are extracted from water and adsorbed as a monolayer on activated carbon,with the highest capacity predicted to be Qe = 23.652mgg -1 , the Langmuir and Freundlich models were used to predict adsorption data.In terms of regression coefficients, the experimental data show that the Langmuir fit more than the Freundlich model. Free energy ΔG , enthalpy ΔH and adsorption entropy ΔS were all calculated using isotherms to be 7652.89(J ∕ mol), 8104 (J ∕ mol) and 22.593(J mol ⁄ * 𝐾) respectively. Additionally, carried out kinetic studies in order to get the psedo second order rate equation for adsorption. Despite its lower price, advanced carbon has the same adsorption capacity as other commercially available adsorbents.
