Preparation of Active Carbon Adsorbents from Elutrilithe via K2CO3 Activation
Abstract:
Active carbon adsorbents suitable for wastewater treatments were prepared from natural elutrilithe by chemical activation with K2CO3. The effect of the activation conditions on the specific area, porosity and ash content of the adsorbent was investigated. The qualities of the adsorbent are further improved via additional simple prior and post treatments. An ideal active carbon adsorbent with a BET specific area of 1236 m2/g and a total pore volume of 0.679 cm3/g was obtained. The adsorbents are hydrophobic in nature and exhibit large adsorption capacities for various phenolic compounds from aqueous solutions.
