现代海洋沉积物中锆的地球化学研究国内尚未有报道。近年我们采用BPHA-三氯甲烷萃取分离偶氮胂Ⅲ比色分析的方法测定了东海47个样品中的锆,同时采用PMBP-苯萃取分离偶氮胂Ⅲ比色分析的方法测定了其中的稀土元素总量(REE~(**)),现将研究的结果报道如下: 东海沉积物中Zr的含量变化于30—435 ppm,按其频率分布主要集中于100—200 ppm,平均为122 ppm;REE的含量变化于85—302 ppm,主要集中于150—250 ppm,平均为186
Geochemistry of zirconium in modern marine sediments has not been reported in China. In recent years, we use BPHA-chloroform extraction arsenazo Ⅲ colorimetric analysis of the 47 samples of the East China Sea zirconium, while PMBP-benzene extraction arsenazo Ⅲ colorimetric analysis of the determination of the rare earth (REE ~ (**)), the results of the study are reported as follows: The Zr content in the sediments of the East China Sea varies from 30 to 435 ppm, and their frequency distribution mainly concentrates at 100-200 ppm with an average of 122 ppm The content of REE varied from 85-302 ppm, mainly in the range of 150-250 ppm with an average of 186
