摘要：
Polypropylene (PP) porous membrane was prepared by track-etching technique. PP film was irradiated with fragments from the fission of uranium to form latent tracks, and chemically etched by potassium dichromate and sulfuric acid. The etching rate of PP was related to the concentration of etching reagent, temperature and time. A mathematical regression relation of etching rate was established from experimental data, and can be used to control the pore size of PP track-etch membrane. (c) 2005 Elsevier Ltd.
