“…The column having a diameter of 2 cm, with bed depth 10 cm, metal ions concentration 10 mg/l, and flow rate 10 ml/min could treat 2.28 l, 2.22 l, and 2.15 l of Zn(II), Pb(II), and Cu(II), respectively, at breakthrough. The results also reported that about 3.74 g and 3.90 g of NCRH were required per liter of Pb(II) and Cu(II) treatment, respectively [118][119][120].…”

A major threat to the comfort of human life has been imposed by increased industrialization and urbanization. The generation and disposal of huge amounts of toxic materials and pollutants have heavily contaminated our environment. Some Organics such as synthetic dyes (SD) and heavy metals (HM) are becoming increasingly prevalent as the most dangerous pollutants in soil and surface water environments. They are causing great concern worldwide due to their toxicity to many life forms.Environmentally friendly utilization of agricultural by-products/waste materials either as raw materials or in production of so-called activated carbons (AC) is an important issue. Because it is apparent from our literature review that the main factors characterizing these materials are their affordability, local availability, and efficiencies in removing many unwanted toxics and pollutants, they therefore could be utilized instead of more conventional but expensive adsorbent materials, particularly in developing countries where many industries lack appropriate individual sewage treatment systems; even where they exist, they lack satisfactory functioning and maintenance because of the lack of good budgets.A number of case studies are supplied in this review. These case studies have pointed to the efficient removal of SD/HM ions from aqueous solutions by the agricultural by-products/wastes in the form of a raw material, signifying spent tea leaves (STL) as a good example. Besides, the efficient removal of such ions by AC produced from these agricultural by-products/wastes has also been given in detail, suggesting a variety of AC agricultural by-products/wastes sources. Both kinds are widely used adsorbents in the treatment of wastewaters. Our review has shown that these adsorbents are characterized by many exceptional physical and chemical features that make them widely used adsorbents in the treatment of wastewaters. The adsorption efficiencies by these substances were also affected by the characteristics of AC, which depend on the physical and chemical properties of the precursor (i.e., agricultural by-products/wastes) as well as on the activation method applied, which is either chemical or physical. The structural properties of the resulting

“…In fact, certain widely available plant materials remain unused resources, thus the use of them could indeed be an environmentally friendly approach too (Ashraf et al, 2011). Various plant-based adsorbent agents have been tested under different conditions, such as seaweed (Basha et al, 2008;Hashim and Chu, 2004), marine algal biomass (Sheng et al, 2004), seafood processing waste sludge (Lee and Davis, 2001), sugar beet pulp (Reddad et al, 2002b), banana peel (Ashraf et al, 2011;Castro et al, 2011;Hossain et al, 2012), papaya wood (Saeed et al, 2005), grape stalk wastes (Villaescusa et al, 2004), neem bark (King et al, 2007), neem biomass (Arshad et al, 2008), tea-waste (Malkoc and Nuhoglu, 2007;Kamsonlian et al, 2011a), sawdust (Garg et al, 2004;Memon et al, 2005), tamarind bark (Prasad and Abdulsalam, 2009), tamarind hull (Verma et al, 2006), potato peel waste (Ahalya et al, 2005), maize corn cob, jatropha oil cake, sugarcane bagasse (Garg et al, 2007), rice husk (Kumar and Bandyopadhyay, 2006), rice straw (Gao et al, 2008), wheat straw (Robinson et al, 2002), wheat shells (Bulut et al, 2007), wheat bran (Sulak et al, 2006), maize leaf (Babarinde et al, 2006), wood and bark (Mohan et al, 2007), teak leaf powder (King et al, 2006), rubber leaf powder (Hanafiah et al, 2006), pine bark (Al-Asheh et al, 2000), saltbush (Sawalha et al, 2005), and olive pomace (Pagnanelli et al, 2003), orange peel (Kamsonlian et al, 2011b), etc.…”

BACKGROUND:Certain crop-based waste materials have been recognized as cost-effective and highly efficient adsorbents for removal and recovery of different kind of heavy metals from aqueous solutions. The ability is strongly attributed to the carboxyl functional group of some pectin substances such as galacturonic acid often found in fruit peels. The present manuscript was aimed at assessing the potential applicability of banana peel for metal removal from contaminated waters. METHODS AND RESULTS:As revealed by laboratory investigations, banana peel contains pectin (10-21%), lignin (6-12%), cellulose (7.6-9.6%), and hemicelluloses (6.4-9.4%). The pectin extraction is reported to have glucose, galactose, arabinose, rhamnose, xylose, and galactouroninc acid. Several studies conducted under different conditions proved that banana peel is capable of adsorbing 5. 71, 2.55, 28.00, 6.88, 7.97, and 5.80 mg/g of Cd

“…Heavy metals are known to have high toxicity and carsinogenic which tends to affect the lives of humans and other living beings. This is because heavy metals are very difficult and furthermore they are resistant to bacteria or decomposition processes which result in excessive accumulation of concentrations in the aquatic environment exposed by heavy metals continuously [10][11][12][13][14] . Cadmium is one of the most toxic and harmful metals.…”

Synthesis of silica gel base on Mount Sinabung's volcanic ash taken from different villages, was carried out. The purposes of this research are to synthesis and characterized by silica gel which was generated base on ash. The method of this research is a sol-gel method. T h e silica gel w as characterized by Fourier Transform Infra Red (FTIR), X-Ray Diffraction (XRD), and Barret Emmet Teller (BET) respectively. The silica gel consists of Si-O-Si and Si-OH groups. XRD data also shows that silica is amorphous. BET data show that the surface area of silica gel is 374.994 m²/g. A fix bed Column of silica gel was used for the removal of Cd(II). The adsorption column used has a diameter of 1.7cm and is filled with 0.5g of silica. the optimum adsorption capacity is: flow rate 4mL / min (21,194 mg / g). The initial optimum concentration is 24 ppm (21.632 mg / g). The optimum pH is pH 6, (21.848 mg / g). The experiment result showed silica adsorbent effective for removal Cadmium
