In this study, a successful degradation of phenol was achieved by a combination of processes, ultrasonic irradiation and periodate. The effect of pH, dosage of IO4-, dosage of initial phenol and ultrasonic irradiation time on the phenol degradation were examined. Furthermore, the impacts of ion intensity on phenol degradation were examined. The findings indicated that the disgrace ratio advanced in acidic conditions and an upper degradation was achieved in combination processes. The current new investigation examined the effect of ion intensity and the findings determined that the principal intensity of solution is an inactive variable on phenol disgrace with these systems. A comparison research among IO4-/ US system and IO4- and US separately determined the COD removal and indicated that an combined method of IO4-/ US system had the best execution.
在本研究中，通过超声辐照和高碘酸盐相结合的工艺成功实现了苯酚的降解。考察了pH值、IO4-用量、初始苯酚用量和超声辐照时间对苯酚降解的影响。此外，还考察了离子强度对苯酚降解的影响。研究结果表明，在酸性条件下降解率提高，且在联合工艺中实现了更高的降解率。当前的新研究考察了离子强度的影响，结果表明溶液的主要强度对这些体系中苯酚的降解是一个非活性变量。IO4-/超声系统与单独的IO4-和超声之间的比较研究确定了化学需氧量的去除情况，并表明IO4-/超声系统的联合方法具有最佳效果。
