Abstract

The Schiff base ligand Salicylidene-3-amino benzoic acid (SAB) was prepared by reacting salicylaldehyde with 3-amino benzoic acid. Its Cu2+ and Co2+ complexes were prepared by reacting ethanolic solutions of SAB with magnetically stirred solution of metal salts in distilled water using microwave-assisted heating for 30 min. The ligand and complexes were characterized on the basis of physical properties, FT-IR, UV-Vis, magnetic susceptibility, XRD and TGA/DTA. Unit cell dimensions obtained from XRD crystallography analysis agreed with the establishment of orthorhombic crystal structure. The spectroscopic studies revealed the presence of -C=N, -C=O, M-O, M-N, -OH and NO3 functional groups and this showed that the ligand coordinated to metal via N and O donors. The thermal decomposition of the complexes indicates the loss of lattice of water and decomposition of the ligand as key to the interpretation of successive weight loss.

Abstract

sources. This study examines Hydroxyiron (III) bentonite (HBC) and kaolin (HKC) composites for phenol removal from aqueous solutions (5–25 mg/L). The composites, produced by mixing bentonite and kaolin with Hydroxyiron (III) in a 3:1 ratio and calcined at 600°C for 1 hour, were tested at pH 2-11 and 25°C, with adsorbent dosages from 0.5 to 2.5 g in 50 mL solutions. Adsorption thermodynamics were developed for 1 hour, and kinetics experiments were performed at 25°C with a range of 10-60 minutes. Adsorption capacity increased with time, temperature, and concentration. HBC and HKC had pH values of 7.20 and 7.37, pHzpc of 10.10 and 11.00, conductivities of 1.657 and 1.763 μS/cm, bulky densities of 1.214 and 1.185 g/cm³, and attrition rates of 27.21% and 27.91%, respectively. XRF, FTIR, and SEM analyses confirmed hydroxyl group presence, indicating hydrogen bonding with phenol. The Blanchard pseudo-second order model best described HBC (R² = 0.906), and the pseudo-first order model best described HKC (R² = 0.957). Data fit the Langmuir model, indicating monolayer adsorption. Positive enthalpy, entropy, and Gibbs free energy values showed endothermic and non-spontaneous adsorption, with physisorption dominating chemisorption. Maximum adsorption efficiencies were 79.952% for HBC and 75.600% for HKC at 60 minutes, suggesting HBC is a more effective adsorbent. These results indicate that HBC and HKC can be used to remove organic pollutants from wastewater.
