【摘要】 <正> 研究大气沉降物,一般可分为大气飘尘和雨水样品两个方面。以前,雨水样品中的微量元素分析大多采用原子吸收光谱、发射光谱和离子选择电极等法。但由于样品中某更多还原

【Abstract】 Instrumental neutron activation analy sis(INAA)method and lyophilizing tech nique have been developed for the simul taneous determination of multielement concentration in insoluble fractions of rain water. The following element concentrations were detected:Ag, Al, As, Au, Ba,Br, Ca, Ce, Cl, Co, Cu, Cs, Cr. Eu, Fe, Ga, Hf, (?), K, La, Lu, Mg. Mn. Na, Nd, Rb. Sb, Sc, Se. Sm. Ta, Tb. Ti,U, V, Yb and Zn. The reliability of thismethod have been checked, In the Iast part of this paper, the linear correlationn coofficients of some elements have bee evaluated, and distribution of elements have been discussed simply.更多还原
