Abstract:

The degradation of patulin in aqueous solution by glow discharge plasma was studied using different acidities and
catalysts. The results showed that patulin could be rapidly and effectively degraded by glow discharge plasma at DC voltage of
600 V and in the current range of 145–155 mA. The condition of pH 4.0 was favorable to the degradation. Fe2+ and hydrogen
peroxide had obvious catalytic effect on the degradation, but nano-zinc oxide slowed down the degradation of patulin.

Key words: glow discharge plasma, patulin, degradation
