摘要
采用紫外光谱法（UV）分析新型阳离子光引发剂二甲苯基碘锗六氟磷酸盐。系统研究了UV法测试条件，采用氯仿重结晶提纯样品、以无水乙醇为溶剂、在Amax=236nm测吸光度，ε=1．8421×10^4L·mol^-1·cm^-1，线性范围为1～80mg·L^-1加标回收率为99．0％。
A novel cationic photoinitinator iodonium salt O, O＇-dimethylphenyl iodonium hexafluorophosphate （DMPI · PF6） has been recrystallized by chloroform and characterized by FTIR and assayed by UV spectroscopy. The analytical conditions of UV spectra have been studied systematically. The reference solution is anhydrous ethanol, detecting A within λmax=236 nm, ε=1. 8421×10^4 L · mol^-1 · cm^-1. The linear range and recovery are 1-80 mg · L^-1 and 99.0%.
