“…The search for another effective and less expensive adsorb is therefore interesting. Several studies have been carried out on the investigation of new precursor less expensive and do not use the forest reserves, such as peat, chitin (Ghorbel-Bellaaj et al, 2011), silica (Givianrad et al, 2013), sawdust (Johannes et al, 2013), bagasse pith and fly ash (Esfandiar et al, 2014;Reinik et al, 2015). From this point of view, the use of bituminous shale as year adsorb is of great interest because of its efficiency, their chemical composition, rich in active functions (Chen et al, 2010;Ichcho et al, 2005).…”

The new adsorbents were prepared from Moroccan oil shale by chemical and physical process .In this study, experimental Plackett-Burman has been used as a screening method to study six factors for the development of materials to adsorbent basis of oil shale Moroccan. The factors have been identified by two levels, To Know temperature (°C), Processing time (min), mass ratio (m precursor/m acid), Pretreatment mixture the precursor with acid, origin of the raw material and type of the activating agent (H2SO4, H3PO4).And it was chosen as a response The maximum quantity of adsorption of the molecule of Methylene blue (Qads in mg/g) and the specific surface measure by the method bet (Sbet in m2/g), The predicted values were in agreement with the experimental values with a coefficient of determination (R2) of 0.98. The model has been validated by experiments subsequent to optimized conditions. The experimental data processing by software JMP 7 showed that the processing temperature The report of oil shale on the acid and activation time were the important effect on the maximal capacity of adsorption of methylene blue. The sample prepared at 237 °C during 215 min with pre-processing has a maximal capacity of adsorption equal to 54mg/g according to model of adsorption of Langmuir and SBET equal to 143 m2/g.

“…Kinetic study shows that data fitted well into pseudo-second-order model. In a recent study by Esfandiar et al [17] on the removal of Mn (II) through a comparative study using sugarcane bagasse and activated carbon as an adsorbent employed the use of Box-Behnken design, effect of pH, adsorbent dosage and initial metal concentration was considered in the study, the optimum adsorption efficiency was attained at pH of 4.5, 12 mg/l metal ion concentration with adsorbent dosage of 15 g/l at 23 ± 2°C. The increase in initial metal concentration reduced the efficiency of adsorption, maximum removal efficiency was found to be 63 and 97 % for sugarcane bagasse and activated carbon respectively but when sugarcane bagasse was treated with HCl its removal efficiency was enhanced up to 99 %.…”

Biomass as Low-Cost Adsorbents for Removal of Heavy Metals from Aqueous Solution: A Review of Some Selected Biomass

Low cost adsorbents have become a major area of consideration to many researchers due to the expense nature of the available activated carbon. Although commercial activated carbon is the most sufficient and efficiently used carbon for the removal of heavy metals ions coming from wastewater, it is faced with a lot of setback such as; the higher the quality of the activated carbon the more expensive it is, the regeneration of the used carbon tends to be very difficult especially in large volume. Due to this different biomass from agricultural by-products have been investigated to replace the commercial activated carbon and most of the findings have indicated a significant removal in terms of heavy metals in synthetic aqueous solution. This study have looked into and reviewed the various low cost adsorbents that have been employed for the treatment of wastewater laden with heavy metals.
