摘要
用四苯硼化钠比浊法测钾时,加入甲醛和聚乙烯醇溶液,将使标准曲线的线性关系得到改善,从而提高了四苯硼化钠比浊法的精密度。
When the tetraphenylboron-sodium turbidimetry is used to determine potassium, formaldehyde and polyvinyl alcohol solution is added so that the linear relationship of standard curve is to be improved, and the precision of turbidimetric method for tetraphenylboron-sodium is raised.
