Activated carbon-supported copper, silver and manganese catalysts (Cu/GAC, Ag/GAC and Mn/GAC) were prepared by impregnation. Orthogonal experiments were conducted to find the optimum preparation conditions including metal loading, calcination temperature and calcination time. Each catalyst was prepared under the optimum conditions. Catalytic activities for decomposition of ozone of Cu/GAC, Ag/GAC, Mn/GAC, activated carbon (GAC) and molecular sieve (MS) were investigated. The comparison experiments showed that Ag/GAC had the highest activity and was an ideal catalyst to remove indoor ozone. X-ray diffraction (XRD) of Cu/GAC, Mn/GAC and Ag/GAC showed that copper and silver were loaded as atoms on activated carbon, while manganese was present as the monoxide. Finally, possible mechanisms for ozone decomposition on the surface of Cu/GAC, Ag/GAC and Mn/GAC are proposed.

This paper studies how chemical modification influences the Saccharomyces cerevisiae adsorption on copper ion and the desorption of nitric acid, and carries out infrared spectrum analysis of native, adsorbing and desorbing saccharomyces cerevisiae. Results show that carboxyl and amino group in Saccharomyces cerevisiae play an important role in the process of adsorbing Cu(II). The adsorption on Cu(II) by Saccharomyces cerevisiae is mainly the process of surface adsorption. The process of biosorption on heavy metals is mainly reversible adsorption; however, there still exists irreversible adsorption. FTIR analysis further indicates that carboxyl and hydroxyl adsorption on Cu(II) is reversible adsorption, which amino group adsorption on Cu(II) is irreversible adsorption.

Few studies were mentioned to illustrate the role of plant hormones-IAA and ethylene in split-pit formation. Here, a random sample of 100 developing fruits from 7-year-old early maturing nectarines (Prunus persica L. Batsch cv. Ruiguang 5) was used as test material. The shape index and growth index of the sampled nectarines was comparatively analyzed to show the relation between fruit un-uniform growth and their split-pit formation. The split-pit fruits were found to have a higher degree of un-uniform growth than that of the normal fruits, which were demonstrated by higher ratio of transverse diameter/lateral diameter and bigger difference between the flesh thickness of the two sides in the middle part of the fruits (along the line of the transverse diameter) about twelve weeks after full anthesis (p < 0.05). Subsequently, a higher degree of unbalanced distribution of IAA and especially ethylene was observed in the split-pit fruits compared to the normal fruits, which may correlate with un-balanced expansion of the nectarines flesh. Higher concentration of IAA and especially ethylene was found in the middle part of the split-pit fruits than those in the sutures, while those in the normal fruits were not significant. Furthermore, the caliosity was specifically observed in the internal surface of the split-pit nectarines endo carp as early as four weeks after full anthesis, but not in the normal nectarines. The occurrence of caliosit in the endo carp may be an early signal of spilt-pit.
很少有研究报道植物激素iaa和乙烯在裂坑形成中的作用。在这里，随机抽取100个7年生早熟油桃(Prunus persica L. Batsch cv.)的发育果实。以瑞光5号为试验材料。通过对取样油桃外形指数和生长指数的比较分析，揭示了油桃果实生长不均匀与裂核形成的关系。劈裂果的生长不均匀程度高于正常果实，表现为开花后约12周左右，果实的横径/外径比值较高，果实中部(沿横径线)两侧果肉厚度差异较大(p < 0.05)。结果表明，劈核果中IAA尤其是乙烯的不平衡分布程度高于正常果，这可能与油桃果肉膨胀不平衡有关。裂孔果中部的IAA浓度，尤其是乙烯浓度高于针孔果中部，而正常果中部的差异不显著。此外，早在花期4周后，裂口油桃内鲫的内表面就出现了明显的光斑，而正常油桃则没有。内源鲤鱼体内出现钙沉积可能是溢坑的早期信号。

Chitosan capped CdS (CdS/CS) composite was prepared by biomimetic synthesis method under mild conditions. Visible light photocatalytic decolorization of Methyl Orange (MO) was carried out by employing this innovative composite catalyst. Effect of catalyst amount, initial dye concentration, irradiation time, pH value, inorganic ions and reuse of the catalyst on decolorization was investigated. The kinetics of photocatalytic decolorization was found to follow a pseudo-first order reaction. UV-Vis spectra were analyzed to indicate that photocatalytic decolorization of the dye by CdS/CS composite catalyst was the synergistic effect of adsorption and degradation of dye actually. Results suggested that photocatalyst of CdS/CS is suitable for potential applications in organic waste removal from water by adsorption and photocatalysis.

A by-product oil shale ash from Huadian was treated with 5 mol/L nitric acid in order to enhance its adsorption capacity. The acid-treated oil shale ash was used as a low cost adsorbent to remove of cadmium from aqueous solutions. The adsorption capacity of samples to remove of cadmium was evaluated by a series of experiments, and the test results indicated that the adsorption capacity was found to increase with increasing the initial concentration of nickel ions solutions, adsorbent dosages, temperature, and pH of solutions. Langmuir adsorption model was used to fit the adsorption isotherms of raw ash and acid-treated ash with R 2 of 0.9938 and 0.9954 at 25degC, respectively. When the initial concentration was 100 mg/L, the pH was 6.0, the particle size was <75 mum, the adsorbent dosage was 15 g/L, the agitation speed was 400 r/min and the adsorption temperature was 25degC, the uptake values of raw ash and acid- treated ash were 7.78 mg/g and 10.53 mg/g, respectively.

Experiments were designed to investigate the bioavailability of mercury and lead in water with Zebrafish (Brachydanio rerio). Their body residues were determined during the absorptions and eliminations in the situation of with and without sediment. The concentrations of mercury and lead were determined by the application of microwave digestion-atomic fluorescence spectrometry. We analyze the Relative Bioavailability Change (%)- Simple Moving Average (Rb-SMA), the dynamics parameters of elimination, determined tissues' concentrations and respectively calculated removal rate. Bioavailability of mercury decreased about 10%, and that of lead decreased about 30% in balance. In the situation of with sediment, muscle mercury absorption increased, and head, stomach uptaking of mercury decreased in zebrafishs; Mercury in tissues was easier to remove than that of without sediment in adsorption process. For lead in the situation of with sediment, bioavailability of it decreased due to muscle lead concentration significant reduced. Mercury had more ecological risks than lead. In addition, although could not affirm, former researches were underestimate mercury's, and overestimate lead's human health risk. Keywords-sediment, bioavailability, lead, mercury, Zebrafish.

With the suspension cells of Arabidopsis thaliana stably expressing the GFP-fimbrin1 fusion protein and confocal microscope, the actin filaments distribution of single cell was investigated in real-time during hyperosmotic exposure. Our study suggested that the maintenance and recovery of normal cell volume is related with actin cytoskeleton, and the reorganization of AFs is following the shrinkage of plasmalemma during plasmolytic process.

Sono-reactors have a promising future in the area of wastewater treatment as one of the advanced technologies. The solution of chlorobenzene(CB) was irradiated by ultrasound in a parallel or orthorhombic multi-frequency sono-reactor and in an ultrasonic bath, then, some reacted solution was analyzed by uv-vis spectrophotometer every 30 min to measure the remained content of chlorobenzene in the solution, and the degradation percentage of chlorobenzene was calculated. It has been found that the degradation percentage of chlorobenzene in orthorhombic ultrasonic fields was greater by 10%~11% than the algebraic sum of degradations of chlorobenzene in individual frequency field, and the degradation percentage in parallel fields was almost as same as the sum of degradation in individual frequency field. Comparing the rates of degradation of CB in different power input, it was found that the increase in amplitude of degradation percentage was inversely proportional to the operating power input. In the same operating frequency, power dissipation of 90 w, and irradiation time of 120 min, the degradation percentage of CB (initial concentration is 50 mg/L) in the reactor studied in the paper was 10.8% which was higher than the degradation percentage of 7.6% in the ultrasonic bath.
