| Abstract: | 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%. |
