Abstract: A method to acquire high quality acrylamide by active carbon refining is offered. Optimum refining conditions have been established by selecting active carbon material, amount, size, refining time and solution pH value. The effect of active carbon refining on the molecular weight of polyacrylamide has been investigated as well.

Key words: acrylamide, refining, active carbon
