Silica Grafted with Cr2O3 and Their Application to the Separation of Petrolene


In this research work natural Ninivite silica rocks reacted with chromium oxide (+3) at high temperature was used to separate Qaiyarah petrolenes employing solvents of different polarities using soxhelet extraction into several fractions and comparing the result from this sample with that of the natural untreated silica gel as indicated by I.R.
