金的三正辛胺棉富集分离氢醌滴定法

Determination of gold hy bydroquinone titrimetric method after its enrichment (separation)with tri n octyl amine cotton

论述了三正辛胺棉的制备及其动态吸附金的条件和解脱方法的研究。采用氢醌滴定法进行测定。方法的测定范围为０５×１０－６～ｘｘ×１０－６，方法的相对标准偏差为ＲＳＤ＝１．５％。

The preparation of tri n octyl amine cotton and the condition of its dynamic adsorption of gold as well as gold desorption method are described in this paper.The hydroquinone titrimetric method is employed for gold determination.The determination range of this method is 0.5×10 -6 ～xx×10 -6 its RSD is 1.5%.This method can be empolyed for quick determination of gold in field work.
