“…The maximum biosorption capacities of the PCL and SCL were obtained 11.52 and 7.40 mg/g, respectively. The biosorption capacities of the studied adsorbents are greater than those obtained for dried Indian sandalwood (4.66 mg/g) and Azadirachta indica (4.7 mg/g) but lower than Pleurotus eryngii (66.6 mg/g) .…”

This study was designed to present a facile and effective biosorbent from Prosopis cineraria and Syzygium cumini leave (PCL and SCL) for fluoride removal. The test was done in batch mode and the effect of contact time (5, 25, 60, 90, and 120 min), initial fluoride concentration level (3, 5, 8, and 12 mg/L), and biosorbent dose (1, 3, 5, 10, and 25 g/L) on the biosorption process were examined. The optimum conditions for the maximum fluoride removal were occurred at 1 g/L biosorbent dose and contact time of 120 (for PCL) and 90 min (for SCL). The results suggested that the pseudo‐second‐order and Langmuir isotherm models described the experimental data well. According to the Langmuir model, the maximum adsorption capacity of fluoride for PCL and SCL was attained 11.52 and 7.4 mg/g, respectively. Based on Boyd and intra‐diffusion models, the biosorption of fluoride onto PCL and SCL was mainly controlled by film‐diffusion. The study revealed the potential use of PCL and SCL as two new effective biosorbents for the removal of fluoride from aqueous solution. © 2019 American Institute of Chemical Engineers Environ Prog, 38: S429–S440, 2019

“…The Δ G values were negative and decreased with temperatures increased, indicating the spontaneity and feasibility of the sorption of matrine on the adsorbent. The negative values of Δ H and Δ S indicated the exothermal nature and the reduction in randomness of the adsorption process . The results confirmed the passive influence of temperature on the matrine sorption process.…”

A novel molecular imprinted polymer (MIP) based on cellulose is fabricated for separation of matrine. Cellulose graft copolymer was first synthesized from cotton linter by atom transfer radical polymerization in ionic liquid with the acrylamide as monomer. Then, the prepared graft copolymer underwent sulfomethylation and subsequent crosslinking in the matrine solution. Effects of the parameters on the reaction degree were discussed, and the structural, component, and morphological characterization of the products were also conducted. The ability of the obtained cellulose‐based MIP (MIP‐SPAM) to adsorb matrine was evaluated by batch adsorption. Results showed that the sorption process was pH dependent, spontaneous, endothermic, and followed the Langmuir adsorption isotherm. Kinetics study revealed that pseudo‐second‐order was closed to the experimental data and both of the membrane diffusion and intraparticle diffusion controlled the matrine adsorption. Moreover, MIP‐SPAM possessed higher selective sorption property for matrine compared to the corresponding nonimprinted polymer. Finally, the MIP‐SPAM could be repeatedly used for five times without any significant loss in the initial binding affinity. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48392.

Common water hyacinth plant (Eichhornia crassipes) found in various water bodies in Assam, India, was used as bioadsorbent for removal of toxic metals (Cu and Pb) from synthetic medium. The functional groups present in the bioadsorbent, water hyacinth plant powder (WPP) were determined by using Fourier transform infra red spectroscopy (FTIR) and surface topography by scanning electron microscopy (SEM) technique. The specific surface area of WPP was also determined. The optimum adsorption properties of WPP was determined by considering pH, agitation time, metal concentration, temperature and the amount of adsorbent. The adsorbent showed good adsorption of toxic metal, Cu and Pb from synthetic medium. Water hyacinth plant was used to treat ten synthetic mediums containing 40, 50, 60 70 and 80 mgL‐1 of the two heavy metals, Cu and Pb. From the batch study, it was observed that the adsorption mechanism for the studied metals follow the 2nd order kinetics and the isotherm study showed that Langmuir model is suitable for explaining the adsorption equilibrium data for bioadsorption of Cu2+ and Pb2+ ions on WPP. For Cu(II) adsorption on WPP, the maximum adsorption was observed at pH 7 while for Pb(II), the maximum adsorption was observed at pH 5.
