项目摘要
1.XRF analysis of fly ashes and leaching of metals from fly ashElemental compositions of fly ash were measured with a X-ray fluorescence spectrometer. The major elements in the fly ash were Ca > K, Na, Cl, Si, and the content of Zn was about 0.5 mol %. Cu and Pb were contained less than 0.05 mol %. Leaching behaviors of the hazardous heavy metals of Cu, Zn and Pb were investigated using aqueous solutions of HCl, HNO_3 and CH_3COOH as eluents in batch and percolation processes.In both processes, Zn was effectively extracted with every eluent used. While, Pb was well extracted with HCl (0.25 M and 0.5 M) and 0.25 M HNO_3 but slightly with 0.5 M HNO_3 and CH_3COOH. Cu was effectively extracted with HNO_3 and CH_3COOH rather than HCl.2.Recovery of metal ions using a water-soluble chelating polymer and a hollow fiberRecovering rate of metal ions (Cu(II) and La(III)) was measured in a circulating mode, where the aqueous solution of water-soluble chelating polymer (polyacrylic acid) flowed in the lumen side of the hollow fiber which was immersed in metal ion solution. Effects of flow rate of the polymer solution and stirring rate of metal ion solution on the recovery rate were examined, and the effective diffusion coefficients of Cu(II) and La(III) trough the membrane wall were determined to be 3.3×10^<-9> m^2/s and 2.8×10^<-9> m^2/s, respectively.3.Immobilization of metal ionsHydrogen phosphates (Na_2HPO_4, K_2HPO_4, MgHPO_4, CaHPO_4) could favorably remove Pb(II), Cd(II), Co(II) and Cu(II) from aqueous solutions. Calcium hydroxyapatite was shown to be useful to immobilize Ti(IV) and Zr(IV).
1.用X射线荧光光谱仪测定了粉煤灰的元素组成。粉煤灰中的主要元素为Ca > K、Na、Cl、Si,Zn的含量约为0.5mol%。Cu和Pb的含量小于0.05摩尔%。以HCl、HNO_3和CH_3COOH为淋洗剂,研究了重金属Cu、Zn和Pb在间歇淋洗和渗滤淋洗中的浸出行为。0.25 M和0.5 M的HCl和0.25 M的HNO_3对Pb有较好的萃取作用,而0.5 M的HNO_3和CH_3COOH对Pb有较弱的萃取作用。2.水溶性螯合聚合物和中空纤维对金属离子的回收利用水溶性螯合聚合物(聚丙烯酸)的水溶液在中空纤维的内腔侧流动,在循环模式下测量金属离子(Cu(II)和La(III))的回收率。考察了聚合物溶液流速和金属离子溶液搅拌速度对回收率的影响,测得Cu(II)和La(III)通过膜壁的有效扩散系数分别为3.3×10 ~(-2)<-9>m^2/s和2.8× 10 ~(-2)m^2/<-9>s(Na_2HPO_4、K_2HPO_4、MgHPO_4、CaHPO_4)对水溶液中Pb(II)、Cd(II)、Co(II)、Cu(II)均有较好的去除效果。羟基磷灰石钙对Ti(IV)和Zr(IV)的析出是有用的。
