Abstract: Abstract A gilsonite from Qingchuan (Sichuan province, China) was separated into several fractions and characterized by various techniques. The vanadyl porphyrins were determined by inductively coupled plasma optical emission spectrometer, ultraviolet-visible spectrophotometry, high-temperature gas chromatography-atomic… read more here.
