Abstract
Using sorption and flame ionization methods, the microelement composition of formation waters associated with Azerbaijani oil fields (Lokbatan and Bibiheybat) was studied. The sorbents used were cross-linked copolymers obtained from co-oligomers of alkenylphenols, formaldehyde, maleic anhydride, and other compounds (three- dimensional structures of 4 types). The influence of the structure of the sorbent and the composition of water on the degree of extraction of microelements was studied. It has been established that cross-linked copolymersobtained on the basis of 4-isopropenylphenol and maleic anhydride have the highest sorption properties.
