库仑滴定法测定烟叶提取物中茄尼醇
Determination of Solanesol by Coulonmetric Titrimetry
【摘要】 本文提出用库仑滴定法测定茄尼醇。以含有1mol·L-1KBr的78%(V/V)醋酸溶液为介质,以5mA恒电流为电解电流,对布尼醇进行库仑滴定,用双铂电极电流法指示滴定终点,得到满意结果.方法简便、准确,不需要标准溶液,不需要昂贵仪器。
【Abstract】 A method for determination of solanesol by coulometric titrimetry has been developed. The experimental result showed that the 78% (V/V) HAc solution containing 1 mol ·L-1 KBr was the best intermediate and 5 mA of current was the best constent current.The result of determination of the samples showed that the Inethod is simple, accurate and no requiring of very expensive instruments.
