“…The XRD of PMG composites exhibited only the very broad peak characteristic of PPy, without any indication of the presence of MZF or GO. The disappearance of the ferrite's diffraction peaks [30] could be attributed, as discussed in our previous publication on MZF/PPy composites [38], to the core-shell's formation in which the amorphous PPy shell completely coated the MZF (acted as core). In addition, the obvious disappearance of the (001) characteristic peak of GO indicated the complete exfoliation, accompanied by the coating of the GO stacked layers during the in situ polymerization process of the PPy matrix [28,39].…”

“…The influence of different experimental conditions viz; mass, pH, initial dye concentration, temperature as well as ionic strength were investigated to determine the dye removal performance of PMG composites. Different doses of adsorbent (10,20,30,50,80, and 100 mg) per 10 mL of dye solution were utilized. The pH value between 2 and 11 was adjusted using 1 M HCl or NaOH.…”

“…In addition, the structural, morphological, and electromagnetic properties of the PPy/MZF/GO (PMG) ternary composites were investigated. MZF was processed using materials from spent Zn-C batteries (SZCBs) via acid leaching and sucrose auto-combustion routes [30]. The GO was synthesized via graphite oxidation, and exfoliation of graphite using Hummer's method [31].…”

“…Extracted filtrate of SZCBs was obtained as explained in our previous publications[30,61], and used with nitrates: Fe(NO 3 ) 2 •9H2 O, Mn(NO 3 ) 2 •4H 2 O, and Zn(NO 3 ) 2 •6H 2 O (BDH, Poole, UK) and commercial sucrose; C 12 H 22 O 11 to prepare Mn 0.8 Zn 0.2 Fe 2 O 4 . Graphite powder (Sigma Aldrich, Munich, Germany), NaNO 3 , KMnO 4 , H 2 O 2, and H 2 SO 4 (BDH, Poole, UK) were used to prepare the GO.…”

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.
