“…5C) was in good agreement with the pseudo-second-order kinetic model as the regression coefficient (R 2 ) was more close to unity for all the different concentration used. Similar results was also reported by Bose et al (2011) and Mondal et al (2017) using Jatropha seed press cake and A. niger, respectively.…”

In this study attempts were made to isolate a Cr-binding fungal population from coal mine soils of Jharkhand, India. A total of 15 fungal isolates belonging to the genera Aspergillus, Penicillium and Fusarium were obtained from the soils. Among them, Aspergillus fumigatus S101 was found to tolerate up to 5 mM Cr(VI) and showed maximum metal uptake capacity of 1.868 mM g-1 biomass in presence of 0.5 mM Cr(VI) within 48 h. The sorption capacity was standardized following Langmuir and Freundlich absorption isotherm models that followed pseudo-second-order kinetics. The biosorption ability of A. fumigatus S101 was maximum at pH 5 and at 30 °C. There was a decrease in metal uptake capacity with increase in biomass, but with the increase in Cr(VI) concentration metal uptake capacity increased. The sorption capacity increased in presence of metal ions such as Fe(III) and Cu(II) showing complete removal of 0.5 mM Cr(VI) within 36 h. Treatment of biomass with Tween 80 resulted in maximum sorption accounting for 100% removal of 0.5 mM Cr(VI) in 24 h. The results suggested that the mycelial mass of A. fumigatus (S101) is capable of efficient removal of Cr(VI) from aqueous solution.

“…According to the authors, the equilibrium time and optimum pH range were observed to be 3 h and 4.0-6.0, respectively. SCSC exhibit a higher adsorption capacity of 115.86 mg/g than commercial activated carbon (21.69 mg/ g) at 300 K. Bose et al (2011) evaluated a biodiesel waste of jatropha seed press cake (JPC) for the elimination of hexavalent chromium ion from aqueous solutions. The chromium metal removal increases with increase in pH as well as concentration.…”

Removal of heavy metals from emerging cellulosic low-cost adsorbents: a review

Heavy metal pollution is a major problems in the environment. The impact of toxic metal ions can be minimized by different technologies, viz., chemical precipitation, membrane filtration, oxidation, reverse osmosis, flotation and adsorption. But among them, adsorption was found to be very efficient and common due to the low concentration of metal uptake and economically feasible properties. Cellulosic materials are of low cost and widely used, and very promising for the future. These are available in abundant quantity, are cheap and have low or little economic value. Different forms of cellulosic materials are used as adsorbents such as fibers, leaves, roots, shells, barks, husks, stems and seed as well as other parts also. Natural and modified types of cellulosic materials are used in different metal detoxifications in water and wastewater. In this review paper, the most common and recent materials are reviewed as cellulosic low-cost adsorbents. The elemental properties of cellulosic materials are also discussed along with their cellulose, hemicelluloses and lignin contents.

“…The linearity of plots revealed that the adsorption followed Langmuir isotherm model. The Langmuir parameter, Q m values obtained in this work were compared with the results reported in literature [56][57][58][59][60] ( Table 3). The essential characteristic of the Langmuir isotherm can also be evaluated by dimensionless adsorption intensity R L given by [61]:…”

Date palm trunk (DPT) was grafted with diethylenetriamine (DETA) followed by triethylamine amine (TEA) using epichlorohydrin as a crosslinking agent. The potential of modified date palm trunk (MDPT) for the effective removal of Cr(VI) from aqueous solution has been investigated. The equilibrium was attained with in 30 min at optimum pH 3.5. The equilibrium adsorption capacity of MDPT increases (49.8 to 89.3 mg/g) as the initial Cr(VI) concentration increases (50-100 mg/L). An adsorbent dosage of 1.2 g/ L can remove Cr(VI) up to 99.95% from its solution (100 mg/L). The adsorption behavior of Cr(VI) is best described by the pseudo-second order model and the calculated equilibrium capacity (90.9 mg/g) agree with the experimental value (89.3 mg/g). Langmuir, Freundlich, and Temkin adsorption isotherm models were applied to represent adsorption data. The equilibrium data were well fitted by the Langmuir isotherm model by revealing the maximum sorption capacity of MDPT (129.8 mg/g). The mechanism of adsorption was also studied using Fourier transform-infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) analysis. Adsorption-desorption studies reveal that MDPT can be used successfully for four cycles with a small recovery loss (5.4%). Recovered Cr(VI) can be reused beneficially for industrial application.
