“…Pseudo-second kinetic model explains the kinetics of this reaction as the chemical interaction between the biosorbent and the sorbent surface in the rate-limiting step (47). Similar to our research, pseudosecond kinetic was found as the most suitable kinetic model to explain heavy metal removal with citric acid functionalized Bougainvillea spectabilis (7), Cd (II) removal with B. spectabilis (11), Alizarin Red S and Bromophenol blue dyes removal with phthalate-functionalized Sorghum bicolor (8), crude oil with chitosan (62), Cr (III) removal with chemically modified Trifolium alexandrinum (14) and heavy metal removal with magnetic adsorbent (15). Kinetic model parameters are shown in Table 1.…”

The purpose of this work was to evaluate the petroleum sorption capacity of heat-killed fungal discs obtained from Aspergillus ochraceus strain. Effect of various parameters such as biosorbent dose (0.5g-2.5g/100mL), petroleum concentration (0.5-5%), pH (4.0-8.0), contact time (1-12h) and re-usability of biosorbent (1-6) were investigated. Accordingly, the highest biosorption capacity was obtained with 1% petroleum concentration, 1.5 g/100mL heat-killed fungal discs, 10h contact time at pH: 5.0 and room temperature. Additionally, each disc was able to actively use for at least 6 more cycles in biosorption experiments. The specific removal rate was calculated as 0.114 day−1, the rate constant and half-life period were also 1.609 day-1, t1/2 = 0.431, respectively. The kinetic study was described by the pseudo-second order model and the equilibrium modeling was found to be well fitted with Langmuir isotherm. The biosorbent(s) were characterized by Focused Ion Beam Scanning Electron Microscopy (FIB-SEM). Over 80% removal of long-chain n-alkanes by the heat-killed fungal discs was confirmed by GC-MS analysis. Since there has been no similar study investigating the sorption of petroleum with heat-killed Aspergillus ochraceous discs, this novel bio-based sorbent with its low cost, environmentally friendly and easy-to-apply properties can be used in advanced biosorption studies.

Heavy metal contamination is a serious concern worldwide. In order to remove heavy metal ions from wastewater efficiently, multifunctinoal biomass-based material have been utilized. Herein, hyperbranched polymer modified cellulose biomass (HBP-CB) derived from textile waste materials ramie fibers was successfully developed by construction of Fe3O4/SiO2/polymer multiple structure through an etch-fill strategy. Specifically, Fe3O4 and SiO2 particles were introduced to the oxidation etching cellulose surface, and subsequently modified by hyperbranched polymer The adsorption behavior of the adsorbent toward two classes of heavy metal ions was investigated. The results indicated that HBP-CB owned excellent adsorption capacities for chromium and Cu(II) with maximum 123.5 mg/g and 149.0 mg/g and magnetic recovery performance in aqueous medium. These are owing to the oxidization etching biomass matrix with a higher BET surface area of 4.61 m2/g and the hybrid multiple structure modified by functional hyperbranched polymer with high dense adsorptive sites on the matrix. The adsorption behavior was well described by pseudo-second-order kinetic model and Langmuir isotherm model, revealing a rapid surface adsorption and monolayer spontaneous chemical adsorption. For recycling, 81% of adsorption capacity could be retained after five recovery cycles. These demonstrate that the hybrid multiple structure based on biomass, nanomaterials and polymer could provide sustainable and high-performance adsorption property for wastewater treatment.
