本文采用一阶导数紫外分光光度法直接测定注射用苯妥英钠的含量。
The Content of phenytoin sodium (for injection) was determined directly by the first order derivative spectrophotometry.
结果酸碱直接滴定法测得的结果比亚硝酸钠法、紫外分光光度法测得的结果偏高，但无统计学差异（P〉0.05）。
The content determined by acid-base titration was higher than those by UV spectrum and sodium nitrite, but they didn't have statistical significance(P0.05).
