“…It may also be due to the changes in osmotic pressure and hydrolyzing effects of metals present in alkaline soil. Similar pattern of Pb(II), Cu(II), Cd(II), Zn(II), and Cr(VI) removal by G. vittiformis was observed in the studies of Cao et al (2010), Elekes, Busuioc, and Ionita (2010), Isildak et al (2003), andT€ uzen et al (2003). …”

“…Previously, different experimental design methodologies such as factorial design, mixture designs (Cao et al 2010;Agarry and Ogunleye 2012), and central composite designs (Ramenarova et al 2011) were used to interpret the removal of metals from multimetal systems. These experimental designs based on Design of Experiments (DOE) majorly helped to reduce the number of experiments (Cao et al 2010). Researches used response surface methodology (RSM) to interpret the removal of three metals from multimetal systems.…”

Soil heavy metal contamination, a major threat due to industrialization, can be tackled by an efficient and economical process called bioremediation. Mushrooms are employed to accumulate heavy metals from soil due to their high metal accumulation potential and better adaptability. The bioaccumulation potential of Galerina vittiformis was already reported for individual metals. At natural conditions, since soil consists of more than one polluting metal, more focus has to be given to multimetal systems. In this study, multimetal accumulation potential was analyzed using central composite design, and the responses obtained were analyzed using response surface methodology. Heavy metals such as Cu(II), Cd(II), Cr(VI), Pb(II), and Zn(II) were subjected to biosorption at 10-250 mg/kg concentrations along with pH 5-8. The results showed that the preference of the organism for the five metals under study was in the order Pb(II) > Zn(II) > Cd(II) > Cu(II) > Cr(VI) at pH 6.5 under multimetal condition. The study also indicates that the metal interaction pattern in multimetal interaction is a property of their ionic radii. The response surface methodology clearly explains the effect of interaction of heavy metals on the accumulation potential of the organism using three-dimensional response plots. The present work suggests that the fungus Galerina vittiformis could be employed as a low-cost metal removal agent from heavy metal-polluted soil.

“…Since the traditional one-factor-at-a-time experiments cannot successfully predict possible interactions between the multi-component industrial effluents (Cao et al, 2010). Therefore, it is vital to develop an efficient method for exploring and elucidating the mechanism in multi-component simultaneous sorption process.…”

This study assessed the biosorption of anaerobic granular sludge (AGS) and its capacity as a biosorbent to remove Pb(II) and methylene blue (MB) from multi-components aqueous solution. It emerged that the biosorption data fitted well to the pseudo-second-order and Langmuir adsorption isotherm models in both single and binary systems. In competitive biosorption systems, Pb(II) and MB will suppress each other's biosorption capacity. Spectroscopic analysis, including Fourier transform infrared spectroscopy (FTIR) and fluorescence spectroscopy were integrated to explain this interaction. Hydroxyl and amine groups in AGS were the key functional groups for sorption. Three-dimensional excitation-emission matrix (3D-EEM) implied that two main protein-like substances were identified and quenched when Pb(II) or MB were present. Response surface methodology (RSM) confirmed that the removal efficiency of Pb(II) and MB reached its peak when the concentration ratios of Pb(II) and MB achieved a constant value of 1.

“…Biosorption is the aptitude of biological materials to remove heavy metals through metabolically mediated or physicochemical pathways of uptake (Norton et al 2004;Cao et al 2010). Many metal-binding mechanisms are involved in biosorption such as micro precipitation, complexation, physical adsorption and coordination (Babel and Kurniawan 2003).…”

The current study deals with evaluation of biosorption feasibility for removal of Cu(II) and Zn(II) by hybrid immobilized biosorbent of Pleurotus sajor-caju and Jasmine sambac. Batch adsorption experiments were carried out to assess the effect of pH, initial metal concentration, biomass dose, temperature and time. The biosorption efficiency of Cu(II) and Zn(II) ions for hybrid immobilized biosorbent increases with rising pH values. The hybrid immobilized biosorbent illustrated the highest biosorption capability at pH 5 for Cu(II), 6 for Zn(II), at 0.05 g/100 mL dose and 100 mg/L initial metal concentration of both ions. Uptake kinetics followed the pseudosecond-order model and equilibrium was described by Langmuir and Freundlich isotherms. Adsorption ratios of Cu(II) and Zn(II) were best fitted to Langmuir isotherm. The best temperature for ion uptake was found to be 30°C.
