A simple and rapid method for the determination of Cu, Pb, Zn, Cd, Co, Ni, Mn, Cr, Fe and Al in the total ,weakly and strongly bound fraction of suspended matter by GFAAS is described. The weakly bound fraction was leached with 0.5mol/L[HCI] ,and the residual or total sample was decomposed in a teflon bomb with HF/aqua regia. The sum of the weakly and strongly bound fraction equals to the total concentration of metals. The precisions are better than±5% for Fe and Al,and ±9% for the other metals. The accuracy...

The sum of the weakly and strongly bound fraction equals to the total concentration of metals. The precisions are better than±5% for Fe and Al,and ±9% for the other metals. The accuracy of the analyses is good from the use of reference materials of Canada estuarine sediments MESS-1 and BCSS-1。

本文介绍了用0.5mol/L[HCl]浸取海洋悬浮物,并在全聚四氟乙烯密闭消化罐中,于98±2℃下用王水+HF消解悬浮物样品,以石墨炉原子吸收分光光度法连续测定其Cu,Pb,Zn,Cd,Co,Ni,Mn,Cr,Fe和Al等10种金属元素的弱结合、强结合颗拉态及总含量的方法。对浸取所用酸的酸度、体积和浸取时间以及消解溶剂、温度和时间等进行了比较和选择。

The adsorption properties and secondary pore structure of REUSY-Ex were studied by using BET method (benzene and n-heptane as absorbates respectively) and N2 adsorption method. The hysteresis loops were observed in the isotherms of N2 adsorption on USY, REUSY and REUSY-Ex, which showed obviously that the secondary pores were produced in the process of hydrothermal treatment. The acid leaching could extract extra-framework aluminum species filled in the secondary pores and micropores of REUSY. The results of...

The adsorption properties and secondary pore structure of REUSY-Ex were studied by using BET method (benzene and n-heptane as absorbates respectively) and N2 adsorption method. The hysteresis loops were observed in the isotherms of N2 adsorption on USY, REUSY and REUSY-Ex, which showed obviously that the secondary pores were produced in the process of hydrothermal treatment. The acid leaching could extract extra-framework aluminum species filled in the secondary pores and micropores of REUSY. The results of 29Si MAS NMR showed that the chemical surroudings of framework silicon are more uniform after acid leaching.

应用高真空重量法(分别以苯和正庚烷为吸附质)和低温N2吸附法对REUSY-Ex的吸附性能和二次孔结构进行了研究.结果表明,在水热处理过程中可产生二次孔结构,且二次孔的形成与水热处理的脱铝深度相关.稀HCl浸取REUSY不仅能浸取出位于其二次孔中的非骨架铝(EFAL)碎片,而且还能浸取出位于微孔中的EFAL。29Si MAS NMR的结果显示,稀HCl浸取后,骨架Si(OAl)的谱宽变窄,裂分效果提高,表明其化学环境单一或均匀.
