2.硫化物和亚硫酸盐的峰出现在有机硫化物和硫酸盐峰之间,但已有的方法还未能优化到将它们分开.

By using an anion exchange column, with 2.5 mLphthalic acid, adjusted with TRIS to pH=4.2, all of the organic sulphur forms were measured together as a first (pseudo) peak (Nieto and Franken Berger, 1985) at 2.0min,while the sulphate ion was retained on the column and its peak appeared with retention time at 4.2 min.
采用阴离子交换柱和2.5ml邻苯二甲酸,用TRIS调节pH至4.2。所有有机硫一起出现在第一个峰(伪峰),保留时间为2.0分钟((Nieto和Franken Berger, 1985) 。硫酸根离子保留在柱上,峰保留时间为4.2分钟。
The sulphide and sulphite peaks were observed between the organic sulphur and sulphate peaks, but the developed method was not optimised for their separation.
硫化物和亚硫酸盐的峰出现在有机硫和硫酸盐的峰之间,但已有的方法不能很好地对其进行分离。
