Biosorption of hexacyanoferrate(III) complex anion to dead biomass of the basidiomycete Pleurotus mutilus: Biosorbent characterization and batch experiments

Bioremediation of Zn(II) by biosorption across aqueous phase on to surface of eucalyptus leaf powder has been investigated in present research work. The adsorptive potential of eucalyptus leaf powder was evaluated as function of pH, temperature, contact time, agitation rate and particle size. Maximum metal ion uptake and percentage removal capacity of eucalyptus leaf powder were 23.5 mg g À1 and 94%, respectively, at optimized pH 5, 20 AE 18C, contact time 6 h, particle size 0.5 mm and agitation rate 200 rpm. The biomass surface analysis revealed the fact that the biomass surface was heterogeneous and porous in nature. The functional groups like amine, amide, carboxyl, hydroxyl, and methyl groups, significantly important for metal ion binding were present on biomass surface in tremendous amount. Additionally, the Fourier transformation IR spectrum analysis of acid and base activated eucalyptus leaf biomass ruled out all the possibilities of the presence of surface functional groups mentioned above. The reaction rate was studied by applying two rate limiting models pseudo first and pseudo second order. Pseudo second order model was found to be more suitable (R 2 ¼ 0.998) in comparison to pseudo first order (R 2 ¼ 0.724). Adsorption equilibrium of batch stirred reaction data fitting shows the dominance of Langmuir isotherm (R 2 ¼ 0.99) against Freundlich isotherm (R 2 ¼ 0.887) model with equipartitional involvement of both film and intra particle diffusion as rate limiting steps at differential status of contact time.Keywords: Bioremediation; Intra particle diffusion; Langmuir isotherm; Pseudo second order reaction; Zn(II) ion IntroductionThe rapid and tremendous industrial development during last decade has increased the heavy metal pollution in environment [1,2]. Heavy metals are non-biodegradable and have tendency to get accumulated inside the human body via incorporation through food chain [3][4][5][6][7]. Major industrial operations unit like metallurgy, steel production, paint and pigment industry, copper smelting unit, acid mine drainage, electroplating, and metal finishing significantly contribute to heavy metal pollution in natural water streams [8][9][10][11][12]. Various remedial technologies/unit operations viz. osmosis, electro coagulation and flocculation, reverse osmosis, solvent extraction, hydroxide precipitation, and membrane separation have been adopted to remove heavy metals across liquid phase [13,14]. In general, all these above mentioned technologies are expensive, lead to generation of secondary chemical sludge containing heavy metals, making the disposal of sludge questionable, and ineffective in removing heavy metals including Zn(II), Cd(II), Pb(II), Cu(II), and Cr(III) at low concentration levels ranging between 1 and 100 mg L À1 [10,[15][16][17][18][19]. Zinc is one of the elements of heavy metal series. Though zinc is an essential element of life but its exposure beyond permissible limit, defined by United States Environmental Protection Agency, World Health Organization, Canadian Wate...

In this study, strain BAPb.1 was isolated from lead mining area and used as an adsorbent to remove lead(II) ions from aqueous solution. The physicochemical characteristics, heavy metal resistance and antibiotic sensitivity of strain BAPb.1 were investigated. Biosorption capacity was evaluated by batch biosorption experiments, and isothermal characteristics were discussed. Atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectrometry (FTIR) were conducted to explore the mechanism for lead(II) adsorption. Based on morphological and physiological characteristics as well as the phylogenetic analysis of 16S rDNA sequences, strain BAPb.1 was identified as a member of the genus Alcaligenes. It exhibited high resistances to multiple heavy metals such as lead(II), copper(II), zinc(II), nickel(II) and chromium(VI), and to antibiotics such as kanamycin, ampicillin, streptomycin, chloramphenicol, and tetracycline. The optimum conditions for maximum biosorption rate of 85.2% and maximum capacity of 56.8 mg g -1 were found at pH of 5, adsorbent dosage of 1.5 g L -1 (dry weight), initial lead(II) concentration of 100 mg L -1 , and contact time of 30 min at 30°C. Biosorption isotherms were well fitted with Langmuir isotherm model. Mechanism analysis reveals that the lead(II) ions may exchange with sodium and potassium ions, and the hydroxyl, carbonyl and phosphate groups on the cell surface can chelate the lead(II) ions, therefore, surface adsorption play significant role in the biosorption process.

“…Previous studies have demonstrated that in the model of pseudo-first order, the increase in the adsorption coefficient (k) is proportional to the number of free sites on the surface of the adsorbent (Chergui et al, 2009). Therefore, the results of obtained k indicate that in the case of MG, at lower pH (4.0 and 6.0), there is a higher number of free sites exposed on the surface which might attract the dye.…”

“…After that, the dye entered through the porosity of the wall fragments and it was adsorbed to the internal active sites (intraparticle diffusion), (Sahmoune & Ouazene 2012). On the other hand, the bilinearity of the data has also been reported as an indicator of the presence of two different types of pores in the adsorbent (macropores and micropores), (Chergui et al, 2009). The process of inactivation of the fungal biomass by wet heat and pressure determines that the fungal wall is lysed, and fragments of different sizes are formed, in which different pore sizes may be present, leaving exposed multiple active sites (Table 5) …”

The triphenylmethane Malachite Green (MG) and Crystal Violet (CV) dyes are cationic dyes and mix with domestic wastewater when dumped; increasing, among others, the chemical and biological oxygen demand and can cause acute toxicity at different trophic levels. Promoting the removal (decolorization) of MG and CV, and laccase activity (54.8 ± 8.9 and 30.6 ± 2.9 UL -1 respectively) by using P. ostreatus viable biomass needed parameters such as pH (4.5 and 6.0), temperature ). In adsorption studies, it was showed that an acidic pH favors the adsorption of both dyes and the model of pseudo-second order describes best the phenomenon of adsorption. Finally, the germination index (GI), using Lactuca sativa seeds for the initial dyes solutions, was < 50%; demonstrating its high phytotoxic effect. When dye solutions were treated with viable biomass, the GI increased, leaving open the possibility to perform future research to determine if the aqueous solutions, post-treated with P. ostreatus, could be used in treatments that generate less toxic water which could be used in processes that do not require potable water.
