“…1, reveal the particular changes in the structures of CBs compared with those of the SC-HIS-CCBs before and after phenol biosorption. Normally, the major peaks of chitosan exhibit around 3600 ~ 3200/cm for -OH and -NH stretching vibration [16]. Fig.…”

“…The immobilization of histidine on the CCBs (HIS-CCBs) was achieved using the same procedure as described previously [15,16]. After washing with 1.5 mol/L of sodium carbonate solution, the CCBs were placed in a recipient and 10% (w/v) solution of histidine in 1.5 mol/L of sodium carbonate solution added.…”

“…To solve this problem, some active functional groups are grafted on the crosslinked chitosan [1,8,9,[15][16][17]. Recently, Saccharomyces cerevisiae (S. cerevisiae), waste biomass originated from beer fermentation broths, has been reported as biosorbent thanks to its low cost and easily available source of biomass [18][19][20][21][22].…”

“…In this regard, S. cerevisiae was immobilized on crosslinked chitosan beads to increase its adsorption capability. Moreover, histidine, an amino acid with special side chain donor groups such as amino and imidazole, was added in order to enhance the chelation properties of chitosan with specific solutes [15,16].…”

The ability of chitosan beads modified with histidine and Saccharomyces cerevisiae using glutaraldehyde as a crosslinking agent (SC-HIS-CCBs) for the biosorption of phenol was studied. The surface of SC-HIS-CCBs was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) analysis. Batch biosorption experiments using the SC-HIS-CCBs were then performed by varying contact time, solution pH (2.0 ~ 7.0), and initial phenol concentration (25 ~ 250 mg/L). The isotherm and kinetic data were fitted by suitable equations including the Langmuir, Freundlich, pseudo-firstorder, and pseudo-second-order equations. Thermodynamic parameters of phenol biosorption on the SC-HIS-CCBs were calculated. Desorption of phenol from the loaded SC-HIS-CCBs was performed with NaOH solution. The biosorption capacity of phenol of 28.4 mg/g on the SC-HIS-CCBs at pH 2.0 and 313 K, determined by the Langmuir equation, indicated the promising potential of such modified chitosan biosorbents.

Removal of antibiotic Ciprofloxacin Hydrochloride from water by Kandira stone: Kinetic models and thermodynamic

In this study, Kandira stone, extensively used as a cladding material for building stone has been examined for the removal of an antibiotic Ciprofloxacin hydrochloride (CIP) from its aqueous solution. Batch experiments were performed to investigate the adsorption kinetics, equilibrium and thermodynamics between the adsorbent surfaces and CIP. The sorption data follows Freundlich isotherm. A chemical adsorption was dominant. The adsorption behaviour of CIP onto Kandira stone followed the pseudo-second-order kinetic model, indicating that the adsorption process can be expressed with the chemisorption mechanism. The intraparticle diffusion process is a rate-controlling step. The adsorption thermodynamic parameters of the free energy change (∆G o
