Suitable oleophilic groups include CH 2 (CH 2 ) 11 P y +, CH 3 (CH 2 ) 15 Py+ and CH 2 (CH 2 ) 11 OSO 3 -, Py representing pyridine, and suitable resins to which they are attached include sulphonated styrene/divinyl benzene copolymer and styrene/divinyl benzene copolymer having -N+(CH 3 ) 3 Cl- groups attached thereto.
