摘　　要：采用微型分离柱流动注射在线分离富集火焰原子吸收法测定硫酸镍电解液中的铅。用本法分析含铅量为１．３３ｍｇ／Ｌ的试样，相对标准偏差（ｎ＝１０）为３．４％，检出限为０．０３ｍｇ／Ｌ。Methods for the separation and preconcentration of micro amount of lead were investigated.A micro column was adapted in flow injection system for on line separation and preconcentration followed by AAS determination of lead in nickel sufate electrolyte.The detection limit of the method was 0.03mg/L,and the relative standard deviation was 3.4% when a sample containing 1.33mg/L lead was determined.
