“…Similar trend was found by [20]. According to [19], MB molecules have sufficient time for the adsorption when long contact period is provided. However, aggregation of dye molecules might occur when longer contact period is applied.This might cause difficulties in diffusion of MB molecules to the adsorbent.…”

A sorption process on low cost sorbents is one the promising methods for removing of these pollutants from aqueous solutions. This report describes use of drinking water treatment sludge which is abundantly available from drinking water treatment plants, t methylene blue (MB) dye from aqueous solutions. The main objective of this work is to determine the optimum conditions for removal of MB dye, a common compound that is used as a model for organic chemicals. optimization of the sorption process. Six independent important factors which are temperature of treatment, pH of solution, dosage of sorbent, initial dy temperature of sorption were investigated using batch sor factorial faced centered central composite design.

“…Similar result has been documented by [18] using montmorillonite clay to remove MB. According to [19], the sorbents may overlap each other which might prevent some of the active sites reached by the MB molecules. Thus, this may explain the observation at the highest dosage.…”

“…Figure 2a clearly . Thus, the dynamics of adsorption process was adequately described by the pseudo-second-order model, and chemisorption was found the rate-controlling step as reported in literature (Dutta et al 2011;Deng et al 2011;Vucurovic et al 2012). Pore and intra-particle diffusion model was also applied to investigate any possible role of diffusion in the mechanism of MB adsorption on CP (Hu et al 2010;Vucurovic et al 2012) as shown in Fig.…”

The objective of this study was to investigate the biosorption of an azo dye (Methylene blue) by a wetland phytomass (Typha angustata) under post-phytoremediation scenario. Thus, the phytomass was used without any chemical modification. The batch adsorption experiments were conducted to evaluate the effects of contact time and temperatures (25-45°C) on the adsorption of methylene blue (MB) from aqueous solution by cattail phytomass (CP). More than 80 % of MB dye was removed from the aqueous solution within first 10 min of the experiment. Langmuir isotherm was modeled to describe the monolayer adsorption of MB dye (R 2 = 0.995) with the maximum adsorption capacity of 8.1 mg/g at 25°C. Pseudo-second-order kinetic model adequately described the kinetics of absorption process (R 2 = 0.999). The adsorption of MB on the cattail phytomass was a spontaneous and endothermic process that was governed by chemisorption. Hence, CP could be applied as a potential low cost biosorbent to treat dyeing wastewater.

“…The increase in temperature aids formation of newer pores and an opening of the existing pores for the liquid extract which leads to more liquid yield. If temperature is increased further, the pore wall of the materials could be collapsed; due to thinning porosity of the particle size as the surface area is reduced (Azargohar and Dalai, 2005) not only this but also increased ash content which offered a resistance to the diffusion of activating agent (Dutta et al, 2011). Figure 14 shows the 3D surface plots obtained from numerical optimization of pyrolysis process where the optimum values of two process parameters for response product were found.…”

Harmful gases are released into the atmosphere through burning of residues which is commonly practiced in Nigeria and can be attributed to climate change issues. Agricultural residues have the potentials to be used as energy and chemical source and meet its deficit in the country. This paper focuses on utilization of lignocellulosic materials obtained from two agricultural residues through renewable technology to produce bio-energy and chemical feedstock. The lignocellulosic materials were extracted from palm fruit (Elaeis guineensis) fibre and physic nut (Jatropha curcas) shell, and pyrolyzed under low temperature and pressure at various particle sizes. The main properties of solid (lignocellulosic) materials were tested and the bio-oil produced was analyzed using GC-MS. Results show proximate analyses (volatile, ash and fixed carbon contents) and ultimate analysis (carbon, oxygen, nitrogen, magnesium, phosphorus and zinc). The pH value of the bio-oil from both residues increased with increase in temperatures. The density, viscosity and calorific value of the palm and physic residue oil are 831.99 and 947.5 kg/m 3 , 0.695 and 1.58 cPa at room temperature, 22.33 and 14.169 kJ/g, respectively. Aromatics and other compounds are major dominant compounds in the palm fruit fibre oil which is characterized for bio-fuel production. Physic nut shell oil contains aromatic ethers, cyclic ethers, secondary amides and organic halogen compound which are important chemical feedstock. Conversion of these residues to useful products will alleviate the energy supply deficit, improve social and economic development, promote clean and healthy atmosphere of the nation and significantly contribute to global climate change mitigation.
