亚硫酸钠浸取-电感耦合等离子体光谱法测定硫物相分析中的自然硫

Determination of Natural Sulfur in Sulfur Phase Analysis by Sodium Sulfite Leaching-Inductively Coupled Plasma Spectroscopy

试样用亚硫酸钠作溶剂,溶解自然硫,用盐酸酸化,配合电感耦合等离子体光谱仪代替碘的容量法进行自然硫的测定。此法打破了传统的用亚硫酸钠浸取,碘容量法测定自然硫,流程简单,干扰物比较少,对测定结果的准确性和稳定性都带来了极大的帮助。

Sodium sulfite was used as solvent, natural sulfur was dissolved, and natural sulfur was determined by acidizing with hydrochloric acid and combining with inductively coupled plasma spectroscopy instead of iodine volume method. This method has simple flow, less interference, high accuracy and stability.
