PVA(poly vinyl alcohol) sponges were prepared and applied to the absorption of water dissolved in kerosine. PVA sponges were very effective for the removal of water from kerosine, and their absorption ability was greatly affected by the washing conditions of PVA sponges after cross-linking reactions. It seems that the washing con-ditions influence the hydrophilic properties of PVA sponges. The absorption ability of PVA sponges may be more close-ly related to the hydrophilic properties than the pore volume. It was found that the absorption rate of PVA sponges for water dissolved in kerosine is proportional to the water concentration to the power of 2.3 and the absorption rate con-stant at 30℃ is 1.03×10^-4ppm^-1.3ㆍhr^-1ㆍliterㆍg^-1. The absorption rate increases with the increase of temperature in the range of 20 50℃, but may converge to a certain value at higher temperatures. It is expected that PVA sponges pre-pared in this research can be directly utilized for the actual dehydration process of kerosine.
