微色谱柱分离/ICP-AES测定环境样品中的痕量硼

Separation of Boron in Environmental Samples by Decompressed Microcolumn of Boric Resin and Determination by ICP-AES

本文采用色谱系统对水样品 (温泉水、卤水 )中的硼进行分离富集 ,探讨了影响其分离富集的条件。实验表明 ,在 p H=8条件下 ,硼可被树脂完全吸附 ,用 3m L 1mol/L硫酸可以从吸附柱上完全解吸硼 ,浓缩物用 ICP- AES进行测定。所建立的方法简便、准确 。

The optimum conditions for separation and preconcentration of boron are studied in this paper. Boron is adsorbed by boric resin at pH 8, and eluted completely by using 3 mL of 1 mol/L H 2SO 4, then determined by ICP AES. The method is simple, accurate and applicable to the separation of trace boron in environmental samples and high salt samples.
