In this paper, the Langmuir-Freundlich isotherm is used to model the interaction of several triazines (desethylatrazine, desisopropylatrazine, simazine, atrazine, propazine and prometryn) with a propazine-imprinted polymer and to explain the observed cross-reactivity. Different rebinding experiments (each herbicide alone or all together in a mixture) were carried out and the experimental bindin...

Rice straw/magnetic nanocomposites (RS/Fe3O4-NCs) were prepared via co-precipitation method for removal of Pb(II) and Cu(II) from aqueous solutions. Response surface methodology (RSM) was utilized to find the optimum conditions for removal of ions. The effects of three independent variables including initial ion concentration, removal time, and adsorbent dosage were investigated on the maximum ...

Boron removal capacity of multi-walled carbon nanotubes (MWCNTs) modified with tartaric acid was investigated in this study. Modification of MWCNTs with tartaric acid was confirmed by Boehm surface chemistry method and fourier transform infra-red (FT-IR) spectroscopy. Experiments were performed to determine the adsorption isotherm and adsorption thermodynamic parameters of boron adsorption on t...

Humic substances in drinking water react with chlorine and form carcinogenic compounds. This study investigates application of SiO -TiO nano particles and determines removal of Humic acid from an aqueous 2 2 solution and also was conducted on both synthetic and actual water samples, was collected from Isfahan located in center of Iran. The effects of various parameters such as pH, contact time ...

The present study investigates the biosorption of cadmium ions from aqueous solution onto unmodified, ultrasound and microwave treated cells of Saccharomyces cerevisiae. FTIR analysis was conducted to characterize the biosorbent. Equilibrium and kinetic studies of unmodified RBW (residual brewery waste) cell yeast and DSM 1333 (pure strain) were conducted by considering the effect of initial ca...

Modification of chitosan biopolymer was achieved by grafting (3-phenyl-1H-pyrazole-4-carbaldehyde) by the Schiff base reaction to synthesize a new chitosan derivative (ChD). The formation of the product was confirmed by FTIR, XRD and CNMR analysis. The grafted molecule provided additional nitrogen bearing groups as binding sites. The new derivative was used to investigate the removal of Cr (VI)...

Molecular imprinted polymers (MIP) are considered one of the most promising selective and novel separation methods for removal phenolic compound in wastewater treatment. MIP are crosslinked polymeric materials that exhibit high binding capacity and selectivity towards a target molecule (template), purposely present during the synthesis process. In this work MIP were prepared in a bulk polymeriz...
