“…The spectra of the Schiff base ligand exhibit a strong band at δ 177.88 ppm due to C=S group. In the complex formation, the position of this band undergoes an up-field shift [24][25][26][27][28] to δ 179.21 and 178.21 ppm. This indicates that sulphur is involved in coordination (S→M linkage).…”

Schiff bases are versatile ligands, synthesized via condensation of primary amines with carbonyl compounds. In this study, equimolar amounts of 4-imidazolecarboxaldehyde and thiosemicarbazide were combined and the Schiff base 4-imidazolecarboxaldehyde thiosemicarbazone was prepared as a new bidentate complexing agent. The synthesized ligand was reacted with palladium (II) and platinum (II) ions yielding air-stable complexes. For characterization purpose, infrared spectra, mass spectra, electronic spectra, thermal analysis, proton nuclear magnetic resonance and 13-carbon nuclear magnetic resonance spectra studies were carried out on the obtained complexes and ligand. The characterization data showed that the ligand acts as a bidentate coordinate to the metal ions through azomethine nitrogen and sulfur atoms. An in vitro antimicrobial investigation was also carried out for the free ligand and its metal complexes against four bacteria; Bacillus cereus, Staphylococcus aureus (Gram-positive), Escherichia coli and Salmonella typhimurium (Gram-negative) and one Fungi; Candida albicans, to assess their antimicrobial properties by disc diffusion technique. Antimicrobial activity of the prepared complexes showed higher activity than the free ligand.

In recent years, the pollution of water sources has become an important concern for industrial development. Especially, contamination with heavy metal ions leads to serious environmental problems and water-borne diseases. Therefore, the synthesis of different low-cost adsorbent materials with high removal efficiency are being researched extensively. In this study, biochar was obtained from torrefied hazelnut shell and used during polyaniline synthesis to obtain Polyaniline/Biochar composite for removal of copper(II) ions from wastewater. During the study, optimal temperature, pH, adsorbent amount and contact time parameters were investigated. The removal efficiency of developed novel composite adsorbent was found to be 89.23% under the optimum experimental conditions. Kinetic studies also confirmed the adsorption performance. The morphological analysis of adsorbent was characterized with thermal gravimetric analysis (TGA). A new nonlinear model was developed for removal efficiency prediction of Polyaniline/Biochar composite adsorbent since the adsorption behavior has been found to be highly complex. The batch experiments of Polyaniline/Biochar were studied to train the model. The consistency between experimental targets and model outputs gives a high correlation coefficient (R 2 =0.9943) and shows that the proposed model can estimate the Cu(II) removal efficiency of adsorbent accurately. Modeling the behavior of Cu(II) adsorption will be helpful to describe a set of operating conditions for amplifying water treatment technology at the industrial level. Moreover, it can be supposed that the modeling approach developed in this study will expedite the advancement of material science in various application fields for a data-driven future wherein the knowledge can be aggregated.
