Parameters influencing elimination of geosmin and 2-methylisoborneol by K₂FeO₄

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.
