摘要
根据盐酸环丙沙星与Zn(SCN)2-4反应生成离子缔合物沉淀的特点，通过用火焰原子吸收光谱法测定沉淀中的锌，可间接测定环丙沙星的浓度.线性范围为1.6×10-4-3.9×10-3 mol·L-1，检出限为2.9×10-5 mol·L-1，回收率为93.6%-109.0%.
A new method of the determination of Ciprofloxacin hydrochloride is developed by using the precipitate that the Ciprofloxacin reacts with Zn(SCN)2 4. The amount of zinc in the precipitate can be determined by flame atomic absorption spectrometry (FAAS), then the content of Ciprofloxacin hydrochloride can be determined indirectly. The drug can be detected in the range of 1.6×10-4-3.9×10-3 mol·L-1，detection limit is 2.9×10-5 mol·L-1, and recovery is 93.6%-109.0%.
