“…However, larger pore space distributions were observed on SEM microgram of ACP than on that of APP. It has been observed that numerous pore space distributions suggests high adsorption capacity [22]. On further magnification of SEM microgram of both adsorbents after simulation, the pore spaces disappeared, revealing ridges.…”

“…Alkyl halides, alkenes, alkynes, amino and nitro compounds were observed after adsorption as against the presence of carboxyl, hydroxyl and carbonyl groups (adsorptive sites) observed before the sorption process. It was obvious that chemical reactions of oxidation and reduction with PAH compound and displacement of certain substances took place in the course of adsorption [22]. Also, peaks at 1026.16 cm -1 and 3216.41 cm -1 representing C=O and O-H were completely absent after adsorption.…”

“…, variations were also observed due to carbonation effects , activation level and difference in the species of the cassava and plantain. It has been reported that the properties of adsorbents and the adsorbing material have overriding influences on the adsorption capacities of the adsorbents [22]. Previous studies attributed the seeming uptake difference to variations in physical and chemical constitutions of the adsorbents.…”

:The present research aimed to prepare low temperature activated carbon from cuesco and oil palm fibrilla in a ratio of 50-50 % w w -1 with an impregnation ratio of 1:2 and 1:3 zinc chloride (ZnCl 2 ) to be used in the oily substances adsorption in synthetic solutions. The biomass was initially washed, reduced in size and sieved with particle sizes between 2 mm and 1 mm. Afterwards, 10 g of cuesco and 10 g of fibrilla were weighed, mixed, homogenized and impregnated with aqueous ZnCl 2 solutions, the impregnated biomass was filtered and heated for 40 min with a ramp of 5°C min -1 from 150°C to 350°C and then activated with 0.1 M HCl.The precursor (mixture of cuesco and fibrilla) was characterized by analysis of Fourier Transform Infrared Spectroscopy (FTIR) and synthesized carbons were characterized by Brunauer Emmett Teller (BET), Scanning Electron Microscopy (SEM) and X-Ray Diffraction (DRX) analysis. The presence of cellulose, hemicellulose and pectin, and activated carbon of zinc and chlorine on the surface of both carbons were found in biomass, the almost total deterioration of the bands corresponding to lignin and cellulose, and surface areas of 23.24 m 2 g -1 and 12.38 m 2 g -1 , respectively.Adsorption tests of methylene blue and iodine index showed that carbon 1:2 showed better adsorption capacity. The experimental adsorption data were best adjusted by Elovich's kinetic model and Freundlich's isotherm. Therefore, the use of mixed biomass for the preparation of activated carbon can be used in the adsorption of oil present in water.

Petroleum refinery effluents contain hazardous aromatic and polyaromatic hydrocarbons that causes environmental degradation, that is, water, land, and air pollution; therefore, it should be properly treated before its discharge into environment. Adsorption serves an efficient route to treatment of refinery wastewater; but the high production cost and selectivity of the modern adsorbent used limits their industrial scale application. On the other hand, activated carbon due to desirable adsorption characteristics and low cost seems to hold the promise if properly modified to improve its efficiency. In this study, Cu and Zn impregnated on activated carbon (AC) derived from waste tires was used for adsorption of hydrocarbon pollutants from wastewater. AC was prepared from scrap tires through thermal pyrolysis, followed by chemical activation with KOH. Cu and Zn were loaded on AC through wet impregnation method. Initial batch mode adsorption experiments were carried out using aniline and phenol as model hydrocarbons, which indicated that maximum adsorption of aniline and phenol over Zn/AC and Cu/AC occurs in 10 min contact time, temperature 30°C, pH 6, 100 ppm initial concentration, and adsorbent dose of 0.1 g/10 mL. The removal of hydrocarbon pollutants from real refinery wastewater was also investigated under optimized conditions. Results show that the COD of the refinery wastewater decreased from 963 to 73 mg/L in case of Cu/AC (92% removal) and 78 mg/L in case of Zn/AC (91% removal), respectively. The adsorbent showed many folds reusability, and in first cycle, the removal efficiency of phenol and aniline was observed to be above 95%, whereas in second, third and fourth cycles, the removal percentage was 85%, 80%, and 70%, respectively.
