用ferrozine分光光度法测定Fe2+时干扰因素的排除
Removing interference in determination of Fe2+ with ferrozine
【摘要】 分析了用ferrozine分光光度法测定Fe2 + 浓度时硼酸硼酸盐缓冲溶液和共存离子S2 -对结果产生干扰的原因 ,提出了在ferrozine进行显色反应前先用HCl酸化处理来消除测定干扰的方法 ,取得了较满意的Fe2 + 测定结果。
【Abstract】 Effects of borate buffer and sulfide on determination of Fe 2+ with ferrozine were studied.Acidification with HCl was proposed prior to introducing ferrozine to the solution containing Fe 2+ to remove the interference from borate buffer and sulfide.The satisfied results of determination of Fe 2+ were obtained.
