Abstract :The aim of this study is to investigate the simultaneous removal of natural and thermally modified insert ignore into journalissuearticles values(biochar); pea shells, malachite green dye and copper heavy metal. Here, the removal of dye and heavy metal ions at the same time depending on different adsorption parameters was studied by using dual biological system. Adsorption parameters were selected as different contact times insert ignore into journalissuearticles values(1-120 min);, different pollutant initial concentrations insert ignore into journalissuearticles values(30-400 mg/L); and different adsorbent dosages insert ignore into journalissuearticles values(0.4-12 g/L);. In addition, adsorption experiments were applied to different isotherm models and kinetic models in order to better reveal the structure of adsorption. As a result of all these studies, natural pea shells have a removal efficiency 70% for copper ions and 94% for malachite green ions, while biochar pea shells have a removal efficiency 85% for copper ions and 99% for malachite green ions. In addition, natural and biochar adsorbents have adapted to the Freundlich isotherm model. These results showed that pea shells can be used as an effective and inexpensive adsorbent for dye and heavy metal removal.
