Abstract
Thioacetylation poly(aryl ether ketone) (AcSPEK-C) as the precursor of thoilation poly(aryl ether ketone) (SHPEK-C) was synthesized via chloromethylation and thioacetylation of a phenolphthalein poly(aryl ether ketone) (PEK-C) successively. Then AcSPEK-C nanofiber mat was prepared by electrospinning technique, after the deacetylation and the acidification reaction, the SHPEK-C nanofiber mat with the average diameter of 570 nm (SEM test) was successfully obtained ultimately. DSC test showed that SHPEK-C had a single glass transition temperature (Tg =300°C). Adsorption isotherms and adsorption kinetics of the static adsorption process were used to examine the fundamental adsorption properties of Hg2+ ions. The results showed that the maximum adsorption capacity was 3.75 mmol Hg g−1. In addition, the SHPEK-C superfine fibrous membrane also showed high recyclable removal efficiency through the adsorption/desorption experiments.
