Overview

Abstract:

In this work, we fabricated crumpled graphite oxides (CGOs) from discharged electrode of waste batteries by cathodic plasma electrolysis process and applied it for arsenic (As) removal from water solutions. Several factors which effect on the removal efficiency of As(III) were investigated, including, pH, initial concentrations, and contact time. After 120 min of experiment (10 mg of CGO in 40 mL of 1 mg/L As(III) solutions), the removal efficiency reached as high as 98.6%. From Langmuir isotherm model, the calculated maximum adsorption capacity (qmax) was found to be 47.39 mg/g. Results from this study showed that CGO could be an effective adsorbent for As(III) removal from water environment and acts as a promising adsorbent for other heavy metals from the contaminated water.
