摘　　要：本文提出了用原子发射光谱法测定大洋多金属结核中硼的方法.测定范围为3～500ppm,相对标准偏差<7%(n=12),采用此法测定碳酸盐、硅酸盐和土壤中的硼,同样可获得满意结果.In this paper a method for the determination of B in deep-sea polymetallic nodules by atomic emission spectrometry has been proposed. The determination range of the method is 3-500ppm. The coefficient of variation is <7%(n=l2). The method has also been used for the determination of B in carbonate, silicate and soil with satisfactory results.
