Abstract
Water is one of the most important compounds for the existence of nature and human life. Nowadays, as a result of increasing industrialization and industrial production, heavy metals pollute clean water resources. Copper (II) ions are the leading metals in the industry. There is a high proportion of copper (II) ions especially in the production of printed electrical and electronic circuit, paper production, silicon synthesis, wood preservation, fertilizer production, oil refining enterprises, paint and pigment production, steel and similar metal industry, motor and motor vehicle production, aircraft industry and metal industry wastes. When copper (II) ions are present in trace amounts, they are beneficial to human health, while excessive amounts show poison effect and cause acute diseases. In this study, for the removal of copper (II) ions in waste water; biochar obtained from torrefied hazelnut shell and was used to synthesize Polyaniline/Biochar composite by comodfification with polianaline. During the study, optimal temperature, pH, adsorbent amount and contact time parameters were investigated. Moreover, in this study, a new nonlinear model was also developed by using temperature, pH, adsorbent dossage and contact time as an input parameters of the synthesised polymeric Polyaniline/Biochar composite for the removal of copper (II) ions.
