摘要
The relationship between polymer support morphology and adsorption of di-(2-ethylhexyl)dithiophosphoric acid (DEHTPA) from alcoholic solution has been studied. As polymer supports investigated are the conventional commercial polymer adsorbents Amberlite XAD-2 and XAD-4 and two microporous polymer adsorbents prepared by post-polymerization crosslinking of swollen chloromethylated gel-type and macroreticular copolymers of styrene and divinylbenzene. Their morphology has been studied by nitrogen adsorption/desorption method. It was found that in the adsorption process DEHTPA fills the pore space gradually from the smallest pores up to pores with a diameter of approximately 10 nm.
