Sulfur copolymer (poly(S-r-CEA)) was synthesized via facile inverse vulcanization of elemental sulfur with 2-carboxyethyl acrylate (CEA). Polysulfide (PS) oligomer was soluble to common solvents including DMF, producing homogenous dope solution with PAN as filler. PS-PAN was electrospun resulting to nanofiber membrane effective for Hg2+ sequestration with recorded maximum capacity of 612 mg g-1 based on Langmuir model isotherm. Kinetics, selectivity and reusability were also evaluated. This work presents new and cheap yet effective material for heavy metal sequestration from contaminated water.
