摘　　要：目的建立汞溴红原料的紫外含量检测法.方法采用紫外分光光度法,以水作参比,在最大吸收波长λ=512.5nm处直接测定吸收度.结果汞溴红在1.68～11.2μg·mL-1浓度范围内与吸收度呈良好线性关系,平均回收率为99.10%,RSD=0.72%.结论此方法简单、快速、可靠.OBJECTIVE To determine the content of mercurochrome raw material by Uv-spectophotometer. METHODS Uv-spectophotometer was applied for directing determination of mercurochrome The detected wavelengths was 512. 5nm. RESULTS The calibration curve was linear from 1.68μg·mL^-1 to 11.2μg·mL^-L The correspondig average recovery was 99.10% with RSD of 0. 72%. CONCLUSION This mothod is simple rapid and precise.
