For recyclability testing, mercury was eluted from the adsorbed biomass with 0.1M HCL, washed with deionized water, and used again for adsorption study.
The amount of mercury adsorbed by the biomass was calculated using the mass balance equation (see Supporting information).
Chemical Modification. A detailed description for the modification of functional groups of AVB is provided in the supporting Information.
Surface Area Measurement. The specific surface area of the lyophilized AVB was determined by a BET surface area analyzer (Quantachrome Instruments, Autosorb-1-c).
The dried biomass was first degassed by evacuation for 2 h at 80 ℃, and the surface area was then determined by N2 sorption method.
Adsorbent Characterization. The experimental details of the zeta potential measurements, FTIR analysis, electron micrographs, and energy dispersive X-ray analysis are described in the supporting information.
Adsorption of Mercury from Industrial Effluents. The removal of mercury by A. versolor biomass was also tested in the case of an actual system. The effluents of chloralkali and battery industries were collected from the northern region of Kolkata, India and the concentration of mercury along with other ions present in the effluents is summarized in Table S1 in the supporting information.
The concentration of different ions was determined following standard methods. The removal of mercury was carried out as described earlier with 25 mL of effluent after adjusting its pH to 6.0.
