摘要：

Geosmin (GSM) and 2-methylisoborneol (2-MIB) are the most common naturally occurring taste and odor compounds in water supplies. Conventional approaches for water treatment exhibit some benefits. However, those protocols are generally ineffective for the elimination of the two compounds. In this paper, an approach on removal of GSM and 2-MIB using K2FeO4 was explored. Detailed methodology was developed. GG-MS was employed to identify the GSM and 2-MIB compounds. Further, the parameters influencing the effect of GSM and 2-MIB removal, such as pH and K2FeO4 amount were evaluated. At pH of 9, GSM and 2-MIB received its maximum value (22.5%, 31.9%). When dealing with both substances simultaneously, K2FeO4 exhibited obvious effects on MIB. More importantly, K2FeO4 can control the production rate of MIB in algae. (C) 2017 Elsevier B.V.
