离聚物（MPET）对水中铬离子的吸附性能研究

研究了离聚物（MPET）粉末对Cr^3 的吸附性能，探讨了不同的吸附温度、时间、pH值和不同的初始浓度对吸附性能的影响，实验发现Cr^3 在较低温度下和pH为4时能被MPETO分末很好地吸附，最大饱和吸附量为11.80mg/g，实验表明MPET废纤维很可能发展成为一种经济的吸附重金属离子的材料。     

电极旋转放电条件下O3合成效率的理论研究

根据低温等离子体理论和电磁场理论，在实验的基础上研究了电极旋转条件下低温等离子体的产生机制和臭氧的合成机制，分析了放电过程中二次放电重叠对臭氧合成的影响，建立了旋转放电与二次放电的理论模型，并根据这一理论模型导出电极旋转条件下的臭氧合成效率与二次放电重叠概率以及电极旋转速度间的理论关系．这一理论结果表明：二次放电重叠使得臭氧合成效率降低，而电极以适当地速度旋转则可以有效地避免二次放电的重叠，从而提高臭氧的合成效率．理论值和实验结果能够较好地吻合．

Enhanced removal of high-As(Ⅲ) from Cl(-Ⅰ)-diluted SO4(-Ⅱ)-rich wastewater at pH 2.3 via mixed tooeleite and(Cl(-Ⅰ)-free) ferric arsenite hydroxychloride formation

An advanced cost-saving method of removal of high-As(Ⅲ) from SO₄(-Ⅱ)-rich metallurgi cal wastewater has been developed by diluting the SO₄(-Ⅱ) content with As(Ⅲ)-Cl(-Ⅰ)-rich metallurgical wastewater and then by the direct precipitation of As(Ⅲ) with Fe(Ⅲ) at pH2.3.As(Ⅲ) removal at various SO₄(-Ⅱ)/Cl(-Ⅰ) molar ratios and temperatures was investigated The results showed that 65.2–98.2%of As(III) immobilization into solids occurred at the SO₄(Ⅱ)/Cl(-Ⅰ) mo...     

Decomplexation of Cu-1-hydroxyethylidene-1,1-diphosphonic acid by a three-dimensional electrolysis system with activated biochar as particle electrodes

The feasibility of decomplexation removal of typical contaminants in electroplating wastewater, complexed Cu(II) with 1-hydroxyethylidene-1,1-diphosphonic acid (Cu-HEDP), was first performed by a three-dimensional electric reactor with activated biochar as particle electrodes. For the case of 50 mg/L Cu-HEDP, Cu(II) removal (90.7%) and PO initial pH 7, acid-treated almond shell biochar (AASB) addition 20 g/L, and reaction time 180 min, with second-order rate constants of 1.10 × 10⁻³ and 1.94 × 10⁻⁵ min⁻¹respectively. The growing chelating effect between Cu(II) and HEDP and the comprehensive actions of adsorptive accumulation, direct and indirect oxidation given by particle electrodes accounted for the enhanced removal of Cu-HEDP, even though the mineralization of HEDP was mainly dependent on anode oxidation. The performance attenuation of AASB particle electrodes was ascribed to the excessive consumption of oxygen-containing functionalities during the reaction, especially acidic carboxylic groups and quinones on particle electrodes, which decreased from 446.74 to 291.48 µmol/g, and 377.55 to 247.71 µmol/g, respectively. Based on the determination of adsorption behavior and indirect electrochemical oxidation mediated by in situ electrogenerated H₂O₂ and reactive oxygen species (e.g., •OH), a possible removal mechanism of Cu-HEDP by three-dimensional electrolysis was further proposed.
