This work investigates the removal of Cd2+, Cu2+, Ni2+, and Pb2+ ions from aqueous solutions using tururi fibers as an adsorbent under both batchwise and fixed‐bed conditions. It was found that modification of the tururi fibers with sodium hydroxide increased the adsorption efficiencies of all metal ions studied. The fractional factorial design showed that pH, adsorbent mass, agitation rate, and initial metal concentration influenced each metal adsorption differently. The kinetics showed that multi‐element adsorption equilibria were reached after 15 min following pseudo‐second‐order kinetics. The Langmuir, Freundlich, and Redlich–Peterson models were used to evaluate the adsorption capacities by tururi fibers. The Langmuir model was found to be suitable for all metal ions. Breakthrough curves revealed that saturation of the bed was reached in 160.0 mL with Cd2+ and Cu2+, and 52.0 mL with Ni2+ and Pb2+. The Thomas model was applied to the experimental data of breakthrough curves and represented the data well. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40883.

confidence: 99%

“…The organic leaching from SBS was in a range characteristic for this group of biosorbents. Some of the materials like soybean straw, wheat straw (8) and banana stem (19) were chemically treated in order to improve their adsorption capacity, and the treatments also resulted in reduced organic leaching. On the other hand, the treatment of corn stalk and corn cob (8) with 5% NaOH reduced their adsorption efficiency and increased leaching of organic matter by about 3 and 7 times, respectively.…”

Secondary pollution of water during the biosorption of heavy metal ions by pristine and sugar beet shreds from bioethanol production

et al. 2018

When biomaterials are used as adsorbents, some compounds present in their structure can be extracted and cause secondary pollution of the treated water. Depending on the type and amount of the secondary pollution, some materials can be unacceptable as adsorbents despite of their good adsorption capacity. Although, it is not a newly discovered phenomenon and it is recognized as a problem, leaching from adsorbents is neglected. The aim of our study is to investigate the secondary pollution of the water during the biosorption of heavy metal ions by pristine and modified sugar beet shreds from bioethanol production. The presence of different elements in the mentioned adsorbents, secondary pollution of the water during the adsorption of heavy metal ions and amount of reducing sugars in the water treated by pristine sugar beet shreds were characterized by the SEM-EDS method, the amount of the leached inorganic and organic matter from the adsorbents (atomic absorption spectroscopy and permanganate index) and Bertrand's method, respectively. Furthermore, the obtained results were compared to the available literature data. Our results showed that according to the valid regulations of emission limit values of the polluting substances in the water and adsorption capacity, the investigated adsorbents have a great potential as biosorbents for practical treatment of wastewaters which contain high concentrations of heavy metal ions.

Maleic and phthalic anhydrides were chemically incorporated onto the banana pseudostem biopolymeric structure through reaction without solvent at the fusion temperatures of the reagents. The new biomaterials showed unequivocal success for these proposed reactions and demonstrated abilities to remove cations from aqueous solutions. Phthalic anhydride pendant chains bonded to biopolymeric structure showed high performance for cation sorption at short times, 60−180 min, to give the maximum sorption capacities of 0.52, 0.54, and 0.59 mmol g −1 for copper, cobalt, and nickel, respectively. Identically, maleic anhydride chains gave 0.27, 0.32, and 0.20 mmol g −1 for the same sequence of cations. The equilibrium data were best represented by the Langmuir model in a linear regression and by the Freundlich model in nonlinear regression procedures. These new biopolymers are promising for ecosystem remediation with advantages in using biopolymers based on a natural, cheap, and abundant raw biomaterial.
