“…Besides that, the RL for RBBR was found to be 0.15 which is less than 0.29 as compared to the result from [16] and this enhanced that the Langmuir isotherm was favorable adsorption of RBBR on activated carbon. The value of qm calculated by Langmuir for MO (59.17 mg/g) and RBBR (35.09 mg/g) which are much lower than the previous result [13,17].…”

Adsorption technology is one of the efficient and facile method used for wastewater treatment. In this research, coconut shell, an agricultural solid waste was converted into activated carbon via furnace induced and zinc chloride chemical activation techniques. The activated carbon was prepared at activation temperature of 600°C. Anionic dyes, Methyl Orange (MO) and Remazol Brilliant Blue R (RBBR) have been selected due to their harmful effect to the environmental and human. Various effect of parameter such as initial dye concentration, initial pH, adsorbent dosage and agitation speed in batch system were investigated to obtain the optimum condition for both dye adsorption on activated carbon. The optimum dye removal efficiency was around 99% when 5g/L of activated carbon was used. Pseudo-second-order model was the best fitted model with highest correlation compared to other kinetic models. The adsorption behaviour of MO was perfectly presented by the Freundlich model while RBBR was well described by Langmuir model. The maximum adsorption capacity for MO was 59.17mg/g and RBBR was 35.09mg/g. Fourier-transform infrared spectroscopy (FTIR) was utilised to analyse the chemical characteristics of activated carbon before and after adsorption.

“…Indeed, its MB adsorption capacity was about 28.5, 3.5 and 2.9 times higher than activated carbons generated from Macore fruit shells [55], cola nut shells [56] and cellulose biocomposite films [57]. Besides, MO adsorption capacity by OSAC 400°C was about 2.5, 2.3 and 1.7 higher than those reported for activated carbons generated from Vitis vinifera [58], a copper sulfide nanoparticle-loaded activated carbon [59], and an activated carbon synthetized from boiler residue [60].…”

“…To deal with these problems, various conventional methods have been developed to eliminate colorants from industrial effluents. They include reduction followed by chemical precipitations [8], ion exchange [9], inverse osmosis [10], coagulation and flocculation [11], oxidation or ozonation [12], membrane separation [13] and adsorption on activated commercial charcoal [14,15]. Most of these methods are however expensive, especially when applied to effluents with high flow rates or high concentration of dyes.…”

Comparative assessment of methylene blue biosorption using coffee husks and corn cobs: towards the elaboration of a lignocellulosic-based amperometric sensor

The ability of coffee husks (CHs) and corn cobs (CCs) as biosorbents for methylene blue (MB) was investigated in batch mode. The energy dispersive X-ray spectroscopy was used for the determination of elemental composition of both biosorbents. Sorption experiments were carried out as a function of temperature, pH and MB initial concentration. Adsorption capacities of both materials significantly increased with the MB initial concentration. Among the various kinetic and adsorption isotherm models, the experimental adsorption data were best fitted in pseudo-second-order kinetic model and Langmuir isotherm model. The maximum adsorption capacities at room temperature were found to be 79.60 and 73.16 mg g −1 for CHs and CCs respectively. Moreover, the great affinity of MB towards CHs led to deep electrochemical experiments shown that CHs can be used as prominent modifier for a carbon paste electrode (CPE). The linear dynamic range of MB was found within the concentration range of 1-125 µmol/L with a detection limit (3σ) of 3 μM. The elaborated sensor was successfully applied for the determination of adsorption capacities of CHs placed into a column for MB biosorption in river water, suggesting that CH-CPE could be an efficient tool for MB detection in environmental samples.
