Modified peach stones by ethylenediamine as a new adsorbent for removal of Cr (VI) from wastewater
The potential of modified peach stone for Cr (VI) removal from wastewater was explored in this work. The properties of the materials were characterized by SEM, TGA, FT-IR, EDX and elemental analysis. It was found that 3 g/L EPS was good enough for removal of Cr (VI) in feed solution, with the maximum adsorption capacity was 24.68 mg/g. The pseudo-second-order kinetic model and Langmuir adsorption model was well fitted with adsorption data. In addition, EPS could be reused for sustainable operation for a number of cycles. All results confirm that EPS has potential for the removal of Cr (VI).

Abstract

The potential of modified peach stone for Cr (VI) removal from wastewater was explored in this work. The properties of the materials were characterized by SEM, TGA, FT-IR, EDX and elemental analysis. It was found that 3 g/L EPS was good enough for removal of Cr (VI) in feed solution, with the maximum adsorption capacity was 24.68 mg/g. The pseudo-second-order kinetic model and Langmuir adsorption model was well fitted with adsorption data. In addition, EPS could be reused for sustainable operation for a number of cycles. All results confirm that EPS has potential for the removal of Cr (VI).
