| 摘 要： | 用棉纤维为原料, 以对均苯四甲酸酐为交联剂, 合成新型多胺螯合纤维(CC-BA-TETA), 并用该材料为分离柱的填充相, 优化其分离条件. 采用CC-BA-TETA分离富集-火焰原子吸收光谱法测定天然水体中痕量Pb的方法, 可分离出天然水体中铅的5种形态: 总铅、颗粒态铅、离子态铅、非离子态铅和总溶态铅.

| Abstract: | In this paper,a new kind of polyamines chelated cellulose CC-BA-TETA(trithylene tetraamine chelated cellulose was cross-linked by 1,2,4,5-benzenettetracarboxylic aciddianhydride) was synthesized with cotton cellulese and used as column packing to optimize conditions of separation.A method for the speciation analysis of lead in water by FAAS with enrihment on CC-BA-TETA was developed.It can measure the contents of total lead,particulate state lead,ionic state lead, non-ionic state lead and total dissolved state lead. |
