“…This relationship has high statistical significance due to P-Value <0.01 as shown in Table 3. adsorption capacity of this study is higher than the results previously reported by Lakherwal, (2016) (7.6569 mg/g of granular AC) and Nabarlatz, (2012) (7.65 mg/g of activated carbon based on a native lignocellulosic precursor) [19,20]. But it is slightly lower than the result of Rahman, (2014) (19.61 mg/g of palm shell AC) [21].…”

Activated carbon (AC) has been proven to be an effective adsorbent for the removal of a variety of pollutants. AC is extensively used for adsorption because its high surface area is welldeveloped internal micro porosity. The objective of this study is to determine the optimal condition of the surface modification process of activated carbon from rice husk (ACRH) using HNO 3 . That increase the functional group, and improve affinity towards certain contaminants of ACRH for increasing the adsorption capacity of Ni 2+ and Cd 2+. Two factors were taken into account as: the concentration of HNO 3 (1, 3, and 5 M), reaction time (1, 2, 3, 4 and 5 hours). The results showed that the optimal condition of the surface modification process was derived at the equilibrium concentration of HNO 3 = 3 M and the equilibrium reaction time = 4 hour. Interestingly, in comparison with the control sample (ACRH not modified), the adsorption capacity of Ni 2+ and Cd 2+ increased from 10.0 to 17.2 mg/g and 10.4 to 29.6 mg/g, respectively.This adsorption capacity of modified ACRH shows the increase significantly.

“…Different methods have been proposed to remove low concentrations of heavy metals from waste streams or drinking water, including precipitation, membrane processes (nanofiltration or reverse osmosis), oxidation, biotreatments, ion exchange, and adsorption, each one having merits and limitations. Among them, adsorption has demonstrated to be economically favorable and technically easy compared, for instance, with reverse osmosis or ion exchange [118].…”

Activated carbon cloths have received growing attention because they offer comparative advantages over the traditional powdered or granular forms of this well-known adsorbent, providing further potential uses for technological innovations in several fields. The present article provides an overview of research studies and advances concerned with the development of activated carbon cloths and their use as adsorbent in environmental applications, mostly reported in the last years. The influence of some fabrics and textile wastes used as precursors, and of main activation process variables on the development and physicochemical, mechanical and/or electrical properties of the resulting activated carbon cloths are first reviewed. Then, investigations dealing with the removal of water and air pollutants by adsorption onto activated carbon cloths, including advances toward optimizing their regeneration after organic vapors saturation, are presented.
