Acid Light Yellow Removal from Wastewater Using Peanut Shell-Based Activated Carbon

Abstract:

Peanut shell-based activated carbon was prepared by 60% zinc chloride activation. The activation temperature was 923K and activation time was 90min. The activated carbon was applied on the removal of acid light yellow from wastewater. The effects of the amount of adsorbent, the initial dye concentration and pH value of solution were investigated. The results showed that the optimum conditions for dye removal: activated carbon dosage of 2.5g/L, initial dye concentration of 50mg/L, pH value of 3. The color removal efficiency attained above 95%. It is concluded that activated carbon developed from peanut shell could be effective and practical for utilizing in dye wastewater treatment.
