摘要:
在pH值为10.32的碱性介质中,双硫腙与三苯基锡发生反应,经二氯甲烷萃取后,在450nm和609nm处产生两个特征吸收峰.450nm处的吸光度与三苯基锡量在0~14mg·L-1范围内,服从Beer定律,其表观摩尔吸光系数为1.21×10-4L·(mol·cm)-1.用于合成样的测定,其回收率在90.6%~106.9%.
Abstract:
The reaction of triphenyltin chloride with dithizone occurs in an alkaline medium of pH 10.32. After extracting with dichloromethane, there emerge two characteristic absorption peaks at 450 nm and 609 nm respeetively. The one at 450 nm shows an absorbance proportional to the concentration of triphenyltin chloride and obeys Beer’s law in the range of 0~14 mg·L~-1 . It shows an apparent molar absorptivity of 1.21×10~-4 L·(mol·cm)~-1 . This method has been applied to the determination of triphenyltin chloride in synthetic sample, with a recovery of 90.6%~106.9%.
