TI  - Synthesis of Polyaniline/Biochar Composite Material and Modeling with Nonlinear Model for Removal of Copper (II) Heavy Metal Ions
AB  - In recent years, the pollution of water sources has become an important concern for industrialdevelopment. Especially, contamination with heavy metal ions leads to serious environmental problems andwater-borne diseases. Therefore, the synthesis of different low-cost adsorbent materials with high removalefficiency are being researched extensively. In this study, biochar was obtained from torrefied hazelnut shelland used during polyaniline synthesis to obtain Polyaniline/Biochar composite for removal of copper(II) ionsfrom wastewater. During the study, optimal temperature, pH, adsorbent amount and contact timeparameters were investigated. The removal efficiency of developed novel composite adsorbent was found tobe 89.23% under the optimum experimental conditions. Kinetic studies also confirmed the adsorptionperformance. The morphological analysis of adsorbent was characterized with thermal gravimetric analysis(TGA). A new nonlinear model was developed for removal efficiency prediction of Polyaniline/Biocharcomposite adsorbent since the adsorption behavior has been found to be highly complex. The batchexperiments of Polyaniline/Biochar were studied to train the model. The consistency between experimentaltargets and model outputs gives a high correlation coefficient (R2=0.9943) and shows that the proposedmodel 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 treatmenttechnology at the industrial level. Moreover, it can be supposed that the modeling approach developed inthis study will expedite the advancement of material science in various application fields for a data-drivenfuture wherein the knowledge can be aggregated.
