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 2? ions in wastewater treatment, and their technical feasibilities were reviewed in studies mainly from 2000 to 2010. They all were compared with each other by metal binding capacities, metal removal performances, sorbent dose, optimum pH, temperature, initial concentration and contact time. Although commercial activated carbon is widely used in wastewater treatment applications, it has high costs. The use of agricultural by-products as adsorbent material to purify heavy metal contaminated water has become increasingly popular through the past decade because they are less expensive, biodegradable, abundant and efficient. Instead of activated carbon, this study was focused on the inexpensive materials such as agricultural and forest waste. It was shown that these alternative adsorbents had sufficient binding capacity to remove Pb 2? ions from wastewater.

“…Heavy metals such as lead and nickel are but two of the species of particular concern environmentally and are discharged to the environment in the wastewaters associated with industries such as mineral processing, non-ferrous metal porcelain enamelling, electroplating, copper sulphate manufacture, ammunitions and battery manufacture [2]. Discharge concentrations for both Pb(II) and Ni(II) can range from 3.4 to 900 mg dm -3 [3]. Pb(II) accumulates in vital organs and bones and causes a number of diseases ranging from anaemia to nervous system degeneration [4].…”

Currently, significant metal-laden waste streams are produced from a number of industries with obvious consequences for the environment. A variety of techniques are being used to treat these wastewaters. One such technique is adsorption and recent focus in this area has been around the preparation of selective adsorbents based on naturally occurring support materials. In our work, a regenerated cellulose wood pulp was grafted with the vinyl monomer glycidyl methacrylate (GMA) and was further functionalised with imidazole to produce a novel adsorbent material, cellulose-g-GMA-imidazole. A series of adsorption studies were carried out on the cellulose-g-GMA-imidazole to assess its capacity in the separate removal of lead and nickel ions (Pb(II), Ni(II)) from aqueous solution. Cellulose-g-GMA-imidazole sorbent showed an uptake of approximately 72 mg g -1 of Pb(II) and 45 mg g -1 of Ni(II) from aqueous solution. The adsorption process in both cases followed the Langmuir model of adsorption and Pb(II) uptake occurred within 30 minutes while Ni(II) uptake was considerably slower at 400 minutes for maximum uptake. In both cases pseudo second order kinetics best describes the overall process for each metal uptake. The cellulose-g-GMA-imidazole material shows significant promise as a sorbent for the removal of both Ni(II) and Pb(II) and other heavy metal ions from aqueous and waste streams.

Abstract-The present work is an attempt to determine the feasibility and reliability of Peepal (Ficus religiosa) Leaf Derived Carbon utilized as an adsorbent for the removal of zinc (II) from aqueous solution. The effects of solution pH, adsorbent dose, temperature, initial metal ionconcentration and contact time on the adsorption process with respect to the zinc (II) removal were investigated. The optimum conditions obtained were 30 min contact time, 0.8g adsorbent dose, 45 0 C, 0.12M Zn and pH 7 for zinc removal. Experimental equilibrium data were analyzed by the Langmuir and Freundlich isotherm models. The results obtained from the experimental work showed that biomass carbon derived from peepal leaves are transformed into adsorbent for removing metal ions from the aqueous solution. Peepal leaf carbon show promising results in removing zinc (II) from aqueoussolution, thus this material could be used as low cost adsorbent to replace the expensive commercial activated carbon during adsorption process.
