“…Salam (2013) investigated the removal of heavy metals from synthetic aqueous solution by adsorption onto carbon nanotubes through a set of batch experiments which showed effective removal of heavy metals [5]. Activated carbon (AC) is a well known strong adsorbent which has been employed to remove heavy metals from different media principally because of its large surface area and high porosity [6][7][8]. Palm shell activated carbon was successfully used to remove Cu from aqueous solution [9]; but high production expenses of AC may limit its use as adsorbent [10].…”

The feasibility of using wood-derived biochar (BC) to remove Pb, Mn, and Cu from landfill leachate was investigated and modeled in this study. The effect of contact time, biochar dosage and particle size on adsorption of the heavy metals onto BC was examined. BC was used in two form i.e. pulverized (PWB) and crushed (CWB) to evaluate the effect of BC particle size on adsorption characteristics. Biochar was produced under the pyrolytic temperature of 740 °C. The kinetics of Pb, Mn, and Cu adsorption onto PWB and CWB were assessed using the pseudo second-order and Elovich models, where both applied models could well describe the adsorption kinetics. Equilibrium adsorption capacity of the heavy metals onto BC in leachate system was evaluated using the Langmuir, non-linearized Freundlich, linearized Freundlich, and Temkin isotherms and found to have the following order for PWB: Non-linearized Freundlich>Temkin>Langmuir>Linearized Freundlich. The Langmuir and linearized Freundlich models could not adequately represent adsorption of the heavy metals onto biochar, especially for CWB. Using the non-linearized Freundlich isotherm significantly reduced adsorption prediction error. The adsorption affinity of PWB for Pb, Mn, and Cu was greater than CWB in all treatments. Wood-derived biochar is suggested to be used for the removal of heavy metals from landfill leachate as an economical adsorbent.

“…Several treatment methods have been used to treat the landfill leachate, such as biological processes (Li et al 2017;Zhang et al 2016;Robinson. 2017), membrane processes (Ahn et al 2002), coagulation and flocculation methods (Wang et al 2015;Liu et al 2012), flotation methods (Adlan et al 2011), adsorption and chemical precipitation (Hur and Kim 2000;Erabee et al 2017), osmosis (Iskander et al 2017), chemical oxidation (Derco et al 2010), Fenton and electrochemical (Vallejo et al 2012), advanced oxidation techniques Hu et al 2011;Zhang et al 2012;Chys et al 2015) and electro-Fenton (Zhang et al 2014). However, these methods are found to have certain shortages such as operating cost, transfer of one phase to another, lower pollutant removal efficiency and decreasing the process performance.…”

Treatment of landfill leachate wastewater by electrocoagulation process using an aluminium electrode was investigated in a batch electrochemical cell reactor. Response surface methodology based on central composite design was used to optimize the operating parameters for the removal of % color and % total organic carbon (TOC) together with power consumption from landfill leachate. Effects of three important independent parameters such as current density (X 1 ), inter-electrode distance (X 2 ) and solution pH (X 3 ) of the landfill leachate sample on the % color and % TOC removal with power consumption were investigated. A quadratic model was used to predict the % color and % TOC removal with power consumption in different experimental conditions. The significance of each independent variable was calculated by analysis of variance. In order to achieve the maximum % color and % TOC removal with minimum of power consumption, the optimum conditions were about current density (X 1 )-5.25 A/dm 2 , inter-electrode distance (X 2 )-1 cm and initial solution of effluent pH (X 3 )-7.83, with the yield of color removal of 74.57%, and TOC removal of 51.75% with the power consumption of 14.80 kWh/m 3 . Electrocoagulation process could be applied to remove pollutants from industrial effluents and wastewater.

“…The agriculture materials consider a favorer option in the search about feasible rout in adsorption process. Nowadays, many different types of agricultural materials used to prepare activated carbon such as sago palm park [7], date pits [8], and industrial waste products (metal hydroxide sludge, carbon waste slurries, and coffee wastes) [9]. In this study, Kenaf core was examined for its ability to remove textile-based cationic methylene blue (MB) dye from synthetic wastewater and compared to the well-known adsorbent, the activated carbon.…”

The removal of textile-based cationic methylene blue (MB) dye from synthetic wastewater was investigated in batch model using low cost agro-based adsorbents named Kenaf core, and the activated carbon. A comparative analysis between these adsorbents was defined via pH, adsorbent dose and contact time on adsorption process, and morphological properties. In addition, isotherms adsorption studies were estimated for determination of the equilibrium adsorption capacity. The experimental observation showed that the optimum pH values for Kenaf core and the activated carbon were 6 and 4 respectively. Meanwhile the optimum adsorbent dosage values for Kenaf and the activated carbon were 1.5g for both. The results showed that a high adsorption efficiency for Kenaf core which was ab out 84% and 92 % for activated carbon. The correlation coefficients ( 2 ) for kenaf core were equal to 0.8789 and 89 for Langmuir and Freundlich isotherm, respectively. Meanwhile, the correlation coefficients ( 2 ) for activated carbon were equal were 0.8974 and 0.7643 for Langmuir and Freundlich isotherms, respectively. The results illustrated that the Kenaf core has a porous and an irregular surface area which make it a suitable adsorbent for dyes in the wastewater.
