A novel wastewater treatment technique using 8 W low-pressure mercury lamps in the presence of uniform-sized microbubbles (diameter = 5.79 μm) was investigated for the decomposition of methyl orange as a model compound in aqueous solution. Photodegradation experiments were conducted with a BLB black light blue lamp (365 nm), a UV-C germicidal lamp (254 nm) and an ozone lamp (185 nm + 254 nm) both with and without oxygen microbubbles. The results show that the oxygen microbubbles accelerated the decolorization rate of methyl orange under 185 + 254 nm irradiation. In contrast, the microbubbles under 365 and 254 nm irradiation were unaffected on the decolorization of methyl orange. It was found that the pseudo-zero order decolorization reaction constant in microbubble system is 2.1 times higher than that in conventional large bubble system. Total organic carbon (TOC) reduction rate of methyl orange was greatly enhanced by oxygen microbubble under 185 + 254 nm irradiation, however, TOC reduction rate by nitrogen microbubble was much slower than that with 185 + 254 nm irradiation only. Possible reaction mechanisms for the decolorization and mineralization of methyl orange both with oxygen and nitrogen mirobubbles were proposed in this study. © 2008 Elsevier B.V.

Macrocyclic host molecules calixarene carboxylic acid derivatives are found to act as powerful extractants for biologically important amino compounds. A series of adsorbents were prepared from a methacrylate-based polymer Amberlite XAD-7 by impregnation with various calixarene derivatives, for adsorptive recovery of amino acid derivatives. The larger macrocycles calix[6]arene and calix[8] arene carboxylic acid derivatives were more effective for adsorption of amino acid derivatives on the impregnated resin than the calix[4]arene derivative. Since adsorption proceeds mainly via electrostatic interaction, the carboxylic acid groups introduced into the calixarene platform were important for adsorption of cationic amino acid derivatives. The adsorption selectivity for amino compounds using adsorbent impregnated with the calix[6] arene carboxylic acid derivative depends simply on the hydrophobicity of the adsorbates. © 2008 Elsevier Ltd.

Adsorption of histidine-containing dipeptides such as carnosine (Car) was investigated using copper(II) immobilized cation exchange resins. Adsorption of Car was enhanced using Cu(II) immobilized resins, on the basis of metal affinity interactions. In particular, iminodiacetic acid chelating resin with immobilized Cu(II) (Cu-IDA) can adsorb Car from saline water. Car was adsorbed on Cu-IDA even in the presence of 1000 mM of NaCl. Adsorption of various amino acids on Cu-IDA was compared under same conditions. Histidine and the histidine-containing dipeptides were selectively adsorbed on Cu-IDA over other amino acids, both in the absence and in the presence of NaCl. Therefore, immobilized metal affinity adsorption is an efficient method for recovering histidine-containing dipeptides from saline water. © 2008 Elsevier B.V. All rights reserved.

Ferrite adsorbents containing magnesium, cobalt, nickel, zinc were prepared in order to remove As (III) and As (V) . They are adsorbents with large specific surface area. The ferrite adsorbents could effectively adsorb As (III) and As (V) at neutral pH. The adsorption percentage of As (III) and As (V) onto cobalt ferrite was larger than the other ferrite adsorbents. The adsorption capacity of cobalt ferrite for As (III) and As (V) was 0.83 and 0.52 mmol/g, respectively. The adsorption capacities of As (III) and As (V) on magnesium ferrites increased with increasing their specific surface area, suggesting that functional groups on the surface participate in the adsorption.

In order to develop highly selective adsorbents for recovery of palladium (II), the palladium (II) -imprinted chitosan derivative (PIPMC) was synthesized using <I>N</I>- [pyridylmethyl] -chitosan (PMC) . The adsorption rate and adsorption equilibrium of precious metals on PIPMC were compared with those on PMC to elucidate the template effects. The adsorption rate of palladium (II) on PIPMC is very fast and equilibrated within one hour, while at least 10 hours is necessary to reach equilibrium by PMC. PIPMC provided the selective chelate formation spaces toward not only templated palladium (II), but gold (III), nickel (II) and copper (II) that commonly form planar complexes. The template effect of palladium (II) was studied by examining the adsorption selectivity and kinetics of palladium (II) using hydrochloric acid and 1 M aqueous ammonium nitrate solution.

The adsorption behavior of arsenic from water on spherical porous silica particles (SiMAG) covered with magnetite was investigated under batch equilibrium conditions at 303K. The specific surface area and the pH at zero point of charge of SiMAG were 540 m<SUP>2</SUP>/g and 4.6, respectively. Both of As (V) and As (III) were adsorbed on SiMAG The adsorption of As (V) increased with decreasing pH, while that of As (III) was slightly dependent on pH. The adsorption capacity of SiMAG towards As (V) was 0.85 mmol/g.
