“…These trends on the efficiency of the biosorption system to remove these metals from mixture were consistent when the metals were presented as individual metal solutions at their corresponding optimum concentrations and pH. Very recently, Lu et al [24] also studied biosorption of lead, copper, and cadmium by Enterobacter sp. J1 in ternary mixture and found that the preference of metal sorption by the bacterium followed the order Pb>Cu> Cd [24].…”

“…Very recently, Lu et al [24] also studied biosorption of lead, copper, and cadmium by Enterobacter sp. J1 in ternary mixture and found that the preference of metal sorption by the bacterium followed the order Pb>Cu> Cd [24]. However, a comparison of these two results from mixture and from individual solutions revealed that while the copper and cadmium removals were severely inhibited, lead removal, on the other hand, was found to be enhanced several times in the mixture.…”

Biosorption of three divalent metals, viz., lead, copper, and cadmium in ternary aqueous mixtures was studied using Phanerochaete chrysosporium in batch shake flasks. The mixtures were prepared containing the metals at their either varying optimum or equal initial concentration combinations in aqueous solution of pH optimum to each of the metals. Following were the optimum initial concentration ranges of the metals in mixture: lead, 60-100 mg/L; copper, 20-60 mg/L; and cadmium, 5-15 mg/L. And, for varying these optimum concentration levels of the metals, a 2(3) full factorial design of experiments was employed. The results revealed that an increase in lead and cadmium concentrations helped in their better biosorption by the fungus, but an increase in initial copper concentration slightly diminished its removal. Statistical analysis of the results in the form of analysis of variance and Student t test gave a clear interpretation on the roles of both the individual metals and their interactions in the uptake of metals from mixture. Compared to the uptake of metals when presented individually, lead biosorption in mixture was found to be enhanced to a degree as high as 99%; on the other hand, copper and cadmium removals from mixtures were inhibited to the extent of 100% and 98%, respectively. However, this extent of inhibition or enhancement in the metal removals compared to the individual removals was less in mixtures containing all equal concentrations of the metals.

“…Factorial design was useful for screening many factors to find the significant few and estimating main effect and interactions [24,25]. RSM was used to predict the biosorption results under different metal compositions [26], instead of finding the optimal combination of different variables which impacted heavy metals removal from wastewater in previous studies [6,27,28]. Two mixture designs, standing for high and low overall metal concentrations with the same metal components, were employed to evaluate the effect of total metal concentration on biosorption capacity.…”

“…Lu et al (2008) used RSM to explore and predict competitive biosorption when different metal compositions interact, demonstrating that the parameters of the empirical model can estimate the multi-metal biosorption process more effectively when employing RSM. For the above reasons, RSM was selected to explain the interactions of multi-components.…”

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.
