Catalysts based on Co(II) supported on active carbon were prepared and loaded in static bed. The hydroquinone would be degraded completely after treated by Catalytic wet peroxide oxidation method with Co(II)/active carbon catalyst. After activate treatment, the active carbon was immerged in cobaltous nitrate solution, then put into a drying oven, Co(II) could be loaded on the micro-surface of carbon. Taking the static bed as the equipment, the absorption of active carbon and catalysis of Co(II) was used to reduce activation energy of hydroquinone. Thus hydroquinone could be drastically degraded and the effluent can be drained under the standard. Referring to Fenton reaction mechanism, experiment had been done to study the heterogeneous catalyzed oxidation mechanism of Co(II). The degradation rate of hydroquinone effluent could be achieved to 92% when treated in four columns at H2O2 concentration 10%, reaction temperature 40℃ , pH 5 and reaction time 2.5h.

The adsorptive behavior of nanometer attapulgite modified by acid to Pb（Ⅱ） was investigated by flame atomic absorption spectrometry （FAAS） in this paper. The mainly effect parameters ott the adsorptive efficiency of Pb（Ⅱ）, such as the acidity of the solution, the amount of attapulgite, oscillation time and static time were studied. Also the influencing factors of the recovery efficiency of Pb（Ⅱ）, including the concentration of hydrochloric acid, the volume of hydrochloric acid, oscillation time and static time were investigated. The adsorptive capacity of Pb（Ⅱ） on nanometer attapulgite was 26.5mg/g and the adsorptive capacity of first cycle and second cycle regenerated nanometer attapulgite were 26.5mg/g and 26.3mg/g, respectively. The results obtained indicated that the regenerated effect was good.

Based on the advantage of high surface area and strong adsorption ability of potassium hexatitanate whisker, a method to determine trace Pb(II) content by combining solid phase extraction with Flame atomic absorption spectrometry (FAAS) was established. The adsorptive behavior of potassium hexatitanate whisker to Pb(II), primary influencing factors of adsorption and elution and effect of coexistence ions were investigated systemically. The optimal analytical conditions were discussed and examined. It was found that the adsorption rate of potassium hexatitanate whisker to Pb(II) was 100% at pH 4.0. Pb(II) could be eluted from potassium tetratitanate whisker with HCl (2mol/L) under boiling water for 30min. The detection limit was 5.75ng/mL, and relative standard deviation was 1.66% (n=9, CPb=2.0μg/mL).

In the last decades, the extensive use of chemical and biological materials has not only seen to an increased transport of environmental pollutants but also, it has interfered and compromised the pristine state of different environmental matrices with emphasis on waterbodies. This has stimulated studies to develop and adopt novel techniques which consider the removal of pollutants with premium on economic feasibility, simple instrumentation, and high performance. In the treatment of water, the removal of trace concentration organic compounds and other numerous polluted water effluents is difficult due to limited affinity of trace compound ions to ion exchange resins. Because of the selective nature;recognition properties;adsorption ability;high stability;and easier preparation of molecular imprints, they are considered attractive and suitable artificial receptors to be applied in analytical separations, drug delivery, and as chemical sensors. In this review, we touch on the fundamentals of molecularly imprinted technologies and underscore some recent advances made in the development of imprinted polymers that are compatible with water and how they can be used in the clean-up of pollutants. The paper finally presents a comprehensive report on some challenges and outlook in the use of MIPs as water treatment sorbent.

A kind of molecularly imprinted polymer (MIPs) with high selectivity was prepared using methacrylic acid (MAA) as functional monomer, ethylene glycol dimethacrylate (EDMA) as crosslinker and Gatifloxacin as template. The effect of various parameters such as volume of solvent, functional monomer dosage, crosslinker dosage and polymerization time were investigated. The selective binding experiment for substrates show that the affinity and selectivity for Gatifloxacin were higher than that for blank polymer. Scatchard analysis show that the MIPs recognized template with two kinds of binding sites. The dissociation constant Kd and maximum adsorption quantity Qmax of these two kinds of binding sites were calculated: Kd1 and Qmax1 of the binding sites with high affinity were 8.67×10-4 mol/L and 28.19μmol/g, while Kd2 and Qmax2 of the binding sites with low affinity were1.05×10-3 mol/L and 33.20μmol/g respectively.

A simple and reliable method has been developed for separation and preconcentration of trace amounts of copper ions in cereals food for subsequent measurement by flame atomic absorption spectrometry （FAAS）. The Cu^2＋ ions are adsorbed selectively and quantitatively during the passage. The retained copper ions were desorbed from the potassium tetratitanate whisker with 10.0mL of 2mol/L sulphuric acid solutions as eluent and were determined by FAAS. The linear range was 0.05μg/mL-0.20μg/mL in the original solution with a correlation coefficient of 0.9998. The detection limit of the proposed method is 2. lng/mL in the original solution （3σ, n=9）. Determination of copper in standard ions showed that the proposed method has good accuracy （recovery was more than 95%）. The method was successfully applied for recovery and determination of copper in cereals food samples

Water is one of the most critical issues of concern in China’s ongoing rapid economic development. The resource is scarce and demand is growing as China becomes more industrialized and urbanized. The situation is exacerbated by natural and anthropogenic events such as climate change, pollution, exorbitant patterns of water consumption, and an uneven distribution of water resources, with devastating impacts on ecosystems, international relations, food security and public health. In this paper, an overview of China’s water resources is presented. Studies on distribution, consumption patterns and pollution of water resources are reviewed in order to understand the over-exploited and unexplored dimensions of the Chinese water landscape. The status of water resources is also studied with an intention of providing information on the dynamics of water quality and quantity. The paper concludes with a discussion on China’s commitment to rebalancing its water growth model and the measures taken to achieve that.
