解:因为所有组分出峰,可用归一化法进行定量
A苯酚 = 1.065*h*W1/2 = 1.065*64.0*0.194
w苯酚 = A苯酚*f苯酚/(total A*f)
= 1.065*64.0*0.194*0.85/[1.065*(64.0*0.194*0.85 + 104.1*0.240*0.95 + 89.2*0.285*1.03 + 70.0*0.322*1.00)]
= 10.5536/(10.5536 + 34.2884 + 26.1847 + 22.54)
= 10.5536/93.5667
=0.113 = 11.3%
w邻甲酚 =34.2884/93.5667 = 0.366 = 36.6%
w间甲酚 =26.1847/93.5667 =0.280 =28.0%
w对甲酚 =22.54/93.5667 =0.241 =24.1%
