【摘要】 <正> 铋是一种金属元素,在周期表中属于第六周期第5族第83位。不处在人体及动物维持生命的那些微量元素系列中（从23位钒到43位钼）[1]、[3]。人血液含铋量一般小于0.01μg·ml^-1[2]—[4]。在治疗消化道疾病如慢性腹泻、胃及十二指肠溃疡时,需长期更多还原

【Abstract】 This paper describes the double wavelength spectrophotometric determination of blood bismuth with satisfactory accuray and recovery.The lower limit for the determination of Bi³⁺ is 1 ug.The method is simple and can be performed with epuipment commonly used by clinical laboratories. Thus,it may,be used as a monitor monitor for the patients who are required to receive bismuth for a long period.更多还原
