MgO doped PbFe2O4 (MgO‐PbFe2O4) is synthesized by co‐precipitation followed by ultrasonication method. The study was carried out for the effective adsorption of hexamethyl pararosaniline chloride dye (HPCD) on MgO‐PbFe2O4 from the industrial effluent. The experimental and theoretical physical models are used to explain the mechanism of the dye adsorption process. The simulation of dye adsorption assuming interaction HPCD + MgO‐PbFe2O4 is proposed from two types (a) adsorption of dye on MgO‐PbFe2O4 surface, and (b) the trapping of the HPCD dye in the pores and cavities present in the MgO‐PbFe2O4 surface. A theoretical measurement displays the parameter n pattern as a solution temperature function was n = 0.373, 0.371, and 0.321 at 298, 308, and 318 K, respectively (i.e., all values were below 1). Thus, during interactions between HPCD and MgO‐PbFe2O4 active sites, horizontal molecular positioning and multi‐locking mechanisms were involved. The kinetic model shows that the HPCD adsorptions on MgO‐PbFe2O4 follow the reaction's pseudo‐first‐order. Langmuir isotherm modeling best fitted and describes the HPCD‐MgO‐PbFe2O4 adsorption system for HPCD dye in 40 min with Qmax at 333.33 (mg L–1). The reused study and application in the removal of dye from the industrial effluent make MgO‐PbFe2O4 effective material for pollution control.

Copper oxide nanoparticles (CONs) are synthesized using the leaf extract of Nyctanthes arbor‐tristis. They are further characterized using FE‐SEM and EDX techniques and successfully used for the removal of Congo Red (CR) dye. To enhance the removal efficiency, the effect of various parameters viz. shaking time, adsorbent dose, pH, etc. are studied. The kinetic model showed that the CR adsorption on CON followed the pseudo‐first‐order reactions. Langmuir isotherm modeling is best fitted and describes the CR‐CON adsorption system for CR dye in 90 min with Qmax at 333.33 (mg/g). At varying temperatures, the statistical physics model computed the number of bound CR dye molecules and the saturation adsorption capacity for both functional groups. At 298, 308, and 318 K, the values of “n” are 0.379, 0.358, and 0.328, respectively, which showed that CR molecules interacted with two and three functional groups of the CON surface through a horizontal adsorption orientation. The role and importance of suggested functional groups on dye adsorption as well as their thermodynamic characteristics are determined using a statistical physics model. The reused study is applied to the CON and their efficiency is excellent up to five cycles, making CON an effective pollution control material that may be commercialized in the near future.

“…The amount of adsorbent is being limited with time because adsorbate molecules occupy most of the active sites at the initial stage of the adsorption process. At a fixed amount of the adsorbent, the initial adsorbate concentration leads to different concentrations of adsorbate molecules on the active sites of adsorbents (Jethave et. al.…”

Rapid industrialization, particularly textile/dyeing, causes substantial surface water contamination by various dyes and pigments globally. Bangladesh’s export-oriented textile industry has grown dramatically in recent decades, causing significant pollution of nearby water bodies. In this work, nano-zinc oxide was synthesized by a precipitation method with PEG 400 and characterized using SEM, XRD and FTIR techniques and found to be fiber-like, perfectly wurtzite and pure. The nano-ZnO was applied to remove acid blue 92, an ionic dye, from aqueous solution to investigate it as an adsorbent. The effects of pH, adsorbent dosage, AB92 concentration and contact time on adsorption process were investigated for optimization. According to the correlation coefficients ( R 2 ) and the fitting of Redlich-Peterson model, the adsorption process followed Langmuir isotherm at lower temperature and Freundlich isotherm at higher temperature with Temkin model. The adsorption process was found to be endothermic and spontaneous. For adsorption thermodynamics, ΔH was found to be +20.32 kJmol -1 , and ΔG was varied from -1.86 to -3.84 kJmol -1 as the temperature increased from 291 to 317 K. The adsorption kinetics exhibited pseudo second order. The Temkin isotherm and Elovich kinetic model suggested that the process to be chemisorption. The nano-ZnO showed tremendous re-usability as an adsorbent for the removal of AB92. The results are suggesting for designing nano-ZnO-based methods to remove organic pollutants efficiently from industrial effluents for ecological and sustainable development. The mechanisms of nano-ZnO fiber formation and anionic dye adsorption on nano-ZnO are also discussed.
