活性炭对双溶质水溶液中痕量有机物的理想吸附

对活性炭吸附水中有机物的吸附等温线研究表明，由IAST理论推导的简化模型可更好地解释活性炭对存在一种主要溶质的双溶质体系中痕量溶质的理想吸附现象，并解释了Henry系数与主要溶质的平衡浓度之间不呈简单的反比关系这一现象。活性炭对含苯酚、苯胺溶液中的氯仿和四氯化碳的吸附实验结果与模型预测值相符。影响Henry系数的主要因素有单溶质溶液的Freundrich参数和主要溶质的平衡浓度。各参数的敏感度分析表明：单溶质溶液的Freundrich参数对活性炭吸附痕量有机物的影响要大于主要溶质的平衡浓度的影响。

Comparison of four supports for adsorption of reactive dyes by immobilized beads

Four materials, sodium carboxymethylcellulose （Na-CMC）, sodium alginate （SA）, polyvinyl alcohol （PVA）, and chitosan （CTS）, were prepared as supports for entrapping fungus Aspergillusfumigatus. The adsorption of synthetic dyes, Reactive Brilliant Blue KN- R, and Reactive Brilliant Red K-2BP, by these immobilized gel beads and plain gel beads was evaluated. The adsorption efficiencies of Reactive Brilliant Red K-2BP and Reactive Brilliant Blue KN-R by CTS immobilized beads were 89.1% and 93.5% in 12 h, respectively. The adsorption efficiency by Na-CMC immobilized beads was slightly lower than that of mycelial pellets. But the dye culture mediums were almost completely decolorized in 48 h using the above-mentioned two immobilized beads （exceeding 95%）. The adsorption efficiency by SA immobilized beads exceeded 92% in 48 h. PVA-SA immobilized beads showed the lowest adsorption efficiency, which was 79.8% for Reactive Brilliant Red K-2BP and 92.5% for Reactive Brilliant Blue KN-R in 48 h. Comparing the adsorption efficiency by plain gel beads, Na-CMC plain gel beads ranked next to CTS ones. SA and PVA-SA plain gel beads hardly had the ability of adsorbing dyes. Subsequently, the growth of mycelia in Na-CMC and SA immobilized beads were evaluated. The biomass increased continuously in 72 h. The adsorption capacity of Reactive Brilliant Red K-2BP and Reactive Brilliant Blue KN-R by Na-CMC immobilized beads was 78.0 and 86.7 mg/g, respectively. The SEM micrographs show that the surface structure of Na-CMC immobilized bead is loose and finely porous, which facilitates diffusion of the dyes.

Electrically enhanced photodegradation of an azodye(Acid Orange Ⅱ) using a Pt/TiO2 film electrode irradiating with an UV lamp

A photoelectrochemical process in the degradation of an azodye(Acid Orange II)on a Pt/TiO2 film electrode was investigated.By using the glass device and the voltage stabilized source of direct current,decolorization ratios higher than 78% were observed during a period of 5h.Comparing this value with the sum of the decolorization ratios obtained by a sole application of electrochemical(lower than 3%)and photochemical(about 23%)procedures, a significant synergic effect between both processes was observed.The effects of adscititious voltage and pH value on the decolorization ratios were obvious while the effect of the amount of aeration was minor.
