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.
