Title A spectrophotometric method for the determination of organic soluble matter in bitumen fumes
Bibliographic information July 2002, Vol.17, No.7, p.495-500. Illus. 15 ref.
Abstract A UV spectrophotometric procedure was validated for the determination of organic soluble matter in bitumen fumes collected by filtration. Ultrasonic extraction was carried out with toluene, followed by UV absorbance measurements at 320nm. A calibration curve was plotted from the same set of samples determined by classical weighing method. Further determinations can also be made using the slope factor of the calibration curve. The procedure is simple and fast, and is less prone to losses than weight measurements. Inter-method comparisons of samples collected from experimental laboratory-generated bitumen fumes commonly used in road paving showed that the three available procedures for the determination of organic soluble matter, namely weighing, infrared and UV yield equivalent results.
