Removal of polycyclic aromatic hydrocarbons from aqueous solution using plant residue materials as a biosorbent

Performance Evaluation of Data Mining Classification in Educational System using Genetic Algorithm

“…Also, large hydraulic pore sizes observed in ACP adsorbent encouraged easy diffusion of the adsorbate [17] and its large surface area increased the possibility of surface heterogeneity which consequently provided greater potential for effective adsorption. Similar observations were abound in the study of [21]Olayiwola (2013).The glaring difference in pore space sizes and distributions observed in the results of the study surface chemistry of the adsorbents could be attributed to the natural effect of different adsorbent species.…”

“…Similar observations were abound in the study of [21]Olayiwola (2013).The glaring difference in pore space sizes and distributions observed in the results of the study surface chemistry of the adsorbents could be attributed to the natural effect of different adsorbent species. Previous studies affirmed that the capacity to adsorb any substance is essentially a function of the pore space distribution of the adsorbent, indicating that large pore size distribution encourages high adsorption capacity because the pore spaces create adsorption sites [22] [17]. Similar observations were made in the study of Uzoije et al 2015b [20], Annadurai et al 2012 [12], and Oyekunle et al 2013 [18].This buttressed the high adsorption capacity of ACP observed in the present study as against the APP which has lower pore space distribution.…”

“…Fluoranthene has nonalternate arrangement hence more soluble and less susceptible to adsorption as indicated on Figures 6a and 6b. In contrast, Pyrene has alternate structural arrangement therefore less soluble than Fluoranthene [16] and by implication more susceptible to adsorption onto solid phase [17] …”

Calcined biomass-modified bentonite clay for removal of aqueous metal ions

“…This is due to the several techno-economic and environmental advantages associated with low-cost adsorbents when compared to other water treatment techniques; cheap, easy to obtain, process and use, available in abundance as waste or nuisance, good efficiency of adsorption and environmentally friendly [5][6][7]. Several low cost adsorbents such as biological materials [6][7][8][9][10][11][12][13][14][15], nanomaterials [16,17] and clays [5,[18][19][20][21][22][23][24] have been investigated. However, most of these adsorbents suffer from limitations such as low efficiency of pollutant removal, technicality, low stability, bleeding, low mechanical strength, non-durability and/or poor re-usability, thus limiting their potential for applications.…”

Biodegradation of 2,6-Dichlorophenol Wastewater in Soil Column Reactor in the Presence of Pineapple Peels-Derived Activated Carbon, Palm Kernel Oil and Inorganic Fertilizer

“…In recent years, extensive researches are focused on the development of alternative and economic activated carbon from agricultural by-products [35][36][37][38][39] that are ubiquitous green waste in the environment and which may cause some serious environmental pollution when filling at a fixed site. However, the use of activated carbon derived from agricultural waste materials as adsorbents for the enhancement of hydrocarbon biodegradation rate in soil is very limited [28].…”
