“…The summarized results in Table 2 also showed that the amount of AR1 adsorbed per unit mass of PMG50 composite at equilibrium (qe,calc) agrees well with the experimentally estimated values (qe,exp) using the PSO model, which confirms this model to discuss adsorption. Table 3 summarizes the performance of the PMG50 composite as an adsorbent for the removal adsorption of AR1 dye, compared with other already reported adsorbents according to their adsorption capacity and time [22,[52][53][54][55][56][57][58]. From the table, it is clear that despite exhibiting better efficiencies than some of the reported adsorbents, it could be considered less efficient for the removal adsorption of AR1 dye compared to many others.…”

Herein, ternary composites from polypyrrole (PPy), Mn0.8Zn0.2Fe2O4 (MZF), and graphite oxide (GO) were prepared to remove acid red dye (AR1) from wastewater. MZF was synthesized using spent Zn–C batteries, acid leaching, and sucrose auto-combustion processes; GO was prepared via oxidation and exfoliation of graphite. The composites were prepared by adding MZF and GO during the in-situ polymerization of pyrrole. Different PPy/MZF/GO (PMG) composites were prepared by changing the weight ratios of the PPy, MZF, and GO. We investigated the prepared composites’ structural, magnetic, and electrical/dielectric properties. We evaluated different experimental conditions’ influences on dye removal performance, such as pH, dosage, dye concentration, temperature, and contact time. XRD, FT-IR, and magnetic properties indicated that PPy completely coated the other contents. The electrical/dielectric properties improved while increasing the GO ratio. The PMG at GO content 50 wt.% (PMG50) showed the most efficient ratio for better removing AR1 from wastewater.

In this study, pectin encapsulated Na-zeolite A particles (P-ZA) was synthesized using the impregnation method and it was used as an adsorbent for adsorption of multicomponent lanthanides ions. The Na-zeolite A (zeolite A) was prepared from natural kaolin by the hydrothermal method, while pectin was isolated from white pith of citrus maxima fruits. Scanning electron microscope (SEM) images suggested that P-ZA composite adopts a nest-like shaped surface morphology occupied by zeolite A particles or pectin encapsulated skeleton system of zeolite A particles. The size of P-ZA particles was approximately 125 μm. The highest adsorption capacity of La 3+ , Ce 3+ , Nd 3+ , Sm 3+ , and Dy 3+ on P-ZA composite is 4.81×10 -5 M, 4.65×10 -5 M, 6.19×10 -5 M, 6.04×10 -5 M, and 6.03×10 -5 M, respectively, at the contact time of 60 mins. The lanthanides ions are adsorbed on the P-ZA surfaces through either ion exchange with Na-zeolite A or coordination with the functional groups of pectin, and are further stabilized by their hydrolysis on the P-ZA surfaces. The results suggest that P-ZA composite has the potential to be utilized as an adsorbent for the initial step of separation and purification of lanthanides after leaching from the metallurgical ores.

“…Kaolin clay is the most common natural inorganic clay, existing in rocks copiously in crystalline structure [ 35 ]. Kaolin mainly consists of kaolinite which has the basic chemical structure of aluminum silicate hydrate (Al 2 Si 2 O 5 (OH) 4 ) [ 36 ]. Thus clay is chemically and thermally stable, economical and high melting point [ 37 ].…”
