目前肥料中砷的测定主要是二乙基二硫代氨基甲酸银分光光度法和砷斑法,此二者方法灵敏度较低,不适用于微量检测,本文经研究建立了原子荧光分光光度法测定肥料中的砷,并对肥料采用了三种不同的消解方法,实验表明,该方法操作简便,灵敏度高,最终结果令人满意。 At present, the determination of arsenic in fertilizer mainly is the silver diethyl dithiocarbamate spectrophotometry and the arsenic spot method, both of which have low sensitivity and are not suitable for trace detection. In this paper, the atomic fluorescence spectrophotometry Arsenic in fertilizer and three different digestion methods for fertilizer. Experiments show that the method is simple, sensitive and the result is satisfactory.
