The porous particle mainly includes cellulose acetate or cellulose, is spherical, and has a 3D network skeleton and communicating pores that include the voids of the skeleton and penetrate from the particle surface to the inside. The retention time of dextran with a molecular weight of 2 million at a flow rate of 0.4 ml/min in a column with an inner diameter of 0.78 cm and a length of 30 cm filled with the porous particles is 20 minutes or more.

A composition is provided for removal of a target substance from a fluid stream. The composition may be used to remove polyfluorinated alkyl substances (PFAS) from water. The composition comprises a support material comprising an alumina; and a sorbent molecule that comprises a core polymer; wherein the core polymer is covalently linked to the support material; and wherein the sorbent molecule further comprises one or more covalently linked sorbent groups. Processes for removal of target substances such as PFAS are also provided.

A membrane includes a polysulfone-based support, a polydopamine (PDA) layer disposed on a surface of the polysulfone-based support, and a silver/polydopamine (Ag/PDA) composite layer disposed on a surface of the polydopamine layer. The polysulfone-based support has a pore size of up to 600 nanometers (nm). The Ag/PDA composite layer contains core-shell structure particles and spherical particles. The core-shell structure particles have a silver nanoparticle core and a polydopamine shell. The spherical particles are silver-decorated polydopamine particles. The membrane can at least partially separate an Erichrome Black T (EBT) dye from an EBT dye/salt containing mixture by rejecting the EBT dye and allowing the EBT dye/salt containing mixture to pass through the membrane.
