“…In general, heavy metal ions in wastewaters can be removed by physical, chemical and biological methods such as biosorption, flocculation, coagulation, precipitation, membrane filtration and electrochemical techniques [6][7][8][9][10]. Among them, biosorption is becoming one of the more attractive alternative methods for the removal of radioactive and heavy metals ions from wastewater [11][12][13][14]. Biosorption is not only cost effective, but it also provides an opportunity for the recycling of waste materials [15,16].…”

“…A variety of low cost fungal materials (native and modified) have been used as biosorbents for the removal of organic pollutants and heavy metal ions from aqueous solutions, including Lentinus sajor-caju [3,[17][18][19], Trametes versicolor [6], Aspergillus niger [14,20], and Lentinus edodes [21][22][23][24][25]. Additionally, uranium biosorption by various microbial biomasses (i.e., fungi, yeast, algae, and unicellular bacteria) are reported in the literature [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These microbial biomasses are capable of uptake of uranium greater than 40 % of their dry biomass weight.…”

Amidoxime modified Trametes trogii pellets were prepared by sequential reaction of fungal surfaces with glutaraldehyde, diaminomaleonitrile and hydroxylamine. Maximum biosorption capacities of the modified and native pellets were found to be 447.4 and 238.2 mg U(VI) g -1 fungal pellets, respectively. Biosorption equilibriums were established in about 45 min and the correlation regression coefficients show that the adsorption process can be well-defined by Langmuir equation. The biosorption of U(VI) ions was well described by the pseudo-second order kinetic model. The variations in enthalpy and entropy for the biosorbents were also calculated.

A study of removal of heavy metal ions from heavy metal contaminated water using agro-waste was carried out with Musa paradisiaca peels as test adsorbent. The study was carried by adding known quantities of lead (II) ions and cadmium (II) ions each and respectively into specific volume of water and adding specific dose of the test adsorbent into the heavy metal ion solution, and the mixture was agitated for a specific period of time and then the concentration of the metal ion remaining in the solution was determined with Perkin Elmer Atomic absorption spectrophotometer model 2380. The effect of contact time, initial adsorbate concentration, adsorbent dose, pH and temperature were considered. From the effect of contact time results equilibrium concentration was established at 60minutes. The percentage removal of these metal ions studied, were all above 90%. Adsorption and percentage removal of Pb 2+ and Cd 2+ from their aqueous solutions were affected by change in initial metal ion concentration, adsorbent dose pH and temperature. Adsorption isotherm studies confirmed the adsorption of the metal ions on the test adsorbent with good mathematical fits into Langmuir and Freundlich adsorption isotherms. Regression correlation (R 2 ) values of the isotherm plots are all positive (>0.9), which suggests too, that the adsorption fitted into the isotherms considered.Capsule Summary: Musa paradisiacal peels is discovered to be an efficient biosorbent for the removal of Pb 2+ and Cd 2+ from their aqueous solutions with removal efficiency > 90%.Cite This Article As: N.

In this research, compound biosorbent peanut shell‐HA (PSH) and millet chaff‐HA (MCH), which were composited by peanut shell (PS) and millet chaff (MC) with lead resistent Aspergillus oryzae (HA), respectively, were used to remove Pb2+ from aqueous solution. The characterize of biosorbents were analyzed by FTIR and SEM. Batch experiments were performed to evaluate the effect of pH, biosorbent concentration, initial Pb2+ concentration and contact time on the Pb2+ removal. The results indicated that the functional groups and surface morphology of PSH and MCH were significantly different after compound procedures. The maximum adsorption capacity qm of PSH and MCH were 43.09% and 83.21% higher than PS and MC, respectively. Meanwhile, the compound biosorbent showed a significant adsorption advantage at the low pH and more efficient in adsorption compared to pristine materials. The adsorption isotherms and kinetics studies demonstrated that the adsorption process can be well fitted by the Langmuir and pseudo‐second‐order model, respectively. Fixed‐bed experiments showed that the MCH possesses stronger fixed bed adsorption capacity (qexp[MCH]=8.30 mg g−1,qexp[PSH]=7.13 mg g−1) and shorter height of mass transfer zone (H[MCH]=6.96 cm, H[PSH]=16.56 cm) than PSH. The compound biosorbents performs better than pristine materials with higher adsorption capacity. This study provides a promising strategy for manufacture of new biosorbent. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1658–1666, 2017
