摘要: 本文采用二阶导数分光光度法直接测定醋酸洗必泰漱口液的含量。实验结果证明:本法简便、正确、重现性好。在50～200μg/ml浓度范围内线性良好。γ=0.9997,RSD=0.6%.Abstract: The paper reportes the direct determination of chlorhexidine Acetate Gargle by Second derivative spectrophotometry. The result shows:This method is simple, accurate and reproducible. The callbration curve is linear in the range of 50μg/ml to 200μg/ml.γ=0.9997,RSD=0.6%
