Applicability of Agricultural By-product as Adsorbent in Wastewater Treatment
نویسنده
چکیده
Although activated carbon adsorption is an efficient process in water treatment applications, high costs involved in both the production of carbon and the operation of adsorption units have caused to search alternative adsorbents. Agricultural by-products are a group of alternative adsorbent, with only one or several adsorption cycles, which is available locally in a cheap and abundant manner. In this review paper, adsorption applications of an agricultural by-product for removal of organic matter and heavy metal are evaluated and discussed. The research shows that the adsorption capacities of activated carbon obtained by carbonization and activation of agricultural by-product vary depending on the precursor matter and activation methods. In general, adsorption capacities of the experimental carbon are similar to those of commercially available activated carbon.

At present, there is growing interest in using low cost, commercially available materials for the adsorption of heavy metals. The major advantages of adsorption technologies are its effectiveness in reducing the concentration of heavy metal ions to very low levels and the use of inexpensive adsorbent materials. In this review, agricultural and forest waste adsorbents were used to remove Pb ions...
