摘要
在碱性条件下 ,以过氧化氢为氧化剂消除共存组分的干扰 ,实现了对栲胶脱硫液中悬浮硫不需分离直接进行快速测定。方法简便快捷、重现性好、准确度高 ,加标回收率为 95.6%~1 0 1 .7% ,结果满意。
A direct and rapid method for the determination of suspended sulfur in tannin desulfurizing extractant is reported in this paper. The co existing components in the extractant are oxidized by the addition of H 2O 2 in an alkaline medium and their interferences are thus eliminated. Hence, no separation is necessary. The proposed method is good both in accuracy and precision. The recoveries obtained were in the range 95.6%~101.7%.
