【摘要】 在酸性条件下,甲醛与高锰酸钾能够产生较弱的化学发光,而盐酸米托蒽醌能够大大地增强该化学发光强度.在一定浓度范围内,增加的发光强度与盐酸米托蒽醌的浓度呈良好的线性关系.由此建立了一种测定盐酸米托蒽醌的流动注射化学发光新方法,方法的检出限为6·4μg/L(IUPAC),线性范围为0·01~1·0mg/L,对0·5mg/L盐酸米托蒽醌平行测定11次,其相对标准偏差为2·8%.更多还原

【Abstract】 A flow injection chemiluminescence(FI-CL) system for determination of mitoxantrone hydrochloride was presented. It was based on the chemiluminescence reaction of formaldehyde with potassium permanganate in sulfuricacid solution. The emission intensity can be enhanced greatly by mitoxantrone hydrochloride. The chemiluminescence intensity was proportional to mitoxantrone Hydrochloride concentration over the range 0.01-1.0 mg/L. The detection limit is 6.4 μg/L and the relative standard deviation is 2.8% for 0.5 mg/L(n=11). This method had been successfully applied to determination of mitoxantrone hydrochloride in injections preparation.更多还原
