The raw sludge (RS) was collected from the secondary sedimentation tank of the municipal wastewater treatment plant in Anqing, China. The RS was subsequently stored in a refrigerator at 4 °C before testing, and all the dewatering tests were completed within one week. The following were the main characteristics of the sludge: moisture content (Mc), 96.33%; total solid (TS), 35,366.7 ± 89.7 mg/L; volatile solid (VS), 11,575.0 ± 45.1 mg/L; pH value, 7.03 ± 0.09; SRF, 1.57 ± 0.0 9 × 1013 m/kg; Wc of dewatered sludge cake, 81.64 ± 0.71%. The steel slag (SS) was obtained from the Wuhan Iron and Steel Corporation in China. The red mud (RM) originated from the Shan Dong branch of the Aluminum Corporation of China and was a residue of bauxite treated using the Bayer process. The chemical and mineral compositions of SS, RS, and RM were analyzed by X-ray fluorescence, as shown in Table 1 . C7H6O3 (AR, 99.5%), C6H8O7·H2O (AR, 99.5%), H2O2 (AR, 30 wt%), and HCl (AR, 37%) were obtained from the Sinopharm Chemical Reagent Company, China. Tetracycline standard compound (>95% purity) was obtained from the Aladdin Chemical Company (Shanghai, China).

Individual solutions of 0.1 M of Gd(NO3)3·6H2O (Aladdin Chemicals), Ca(NO3)2·4H2O (Xi-Ya Chemicals), Ba(NO3)2 (JHD Chemicals) and Co(NO3)2·4H2O (Aladdin Chemicals) were prepared by dissolving the nitrates in distilled water. The amount was according to the stoichiometry of perovskite Gd1−xCaxBaCo2O5+δ (0 ≤ x ≤ 0.4). EDTA (Ling-Feng Chemicals) and C6H8O7·H2O (Sinopharm Chemicals) were used as chelation agents and NH4OH (Ling-Feng Chemicals) was applied to adjust the pH (9) of solution mixture. The mixture was kept stirring at 75 °C for 12 h and then heat-treated at 200 °C for 8 h to form the solid precursor. Then the mixture was calcined at 900 °C in air for 4 h to yield the final products.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
