Removal of 2-MIB and geosmin by electrogenerated persulfate: Performance, mechanism and pathways.
Chemosphere, 2017In this study, the degradation of 2-methylisoborneol (2-MIB) and geosmin (GSM) was evaluated by electrochemical oxidation (EO) using boron-doped diamond (BDD) electrode. Both 2-MIB and GSM could be degraded efficiently in sulfate electrolyte compared to inert nitrate or perchlorate electrolytes, implying that in-situ generated persulfate may be ...

2-Methylisoborneol (2-MIB), a natural odorous substance, is widely distributed in water environment, but there is a paucity of information concerning its systemic toxicity. Herein, we investigated the effects of 2-MIB exposure on developmental parameters, locomotive behavior, oxidative stress, apoptosis and transcriptome of zebrafish. Zebrafish embryos

Degradation mechanisms of geosmin and 2-MIB during UV photolysis and UV/chlorine reactions.
Chemosphere, 2016We conducted chlorination, UV photolysis, and UV/chlorin reactions to investigate the intermediate formation and degradation mechanisms of geosmin and 2-methylisoborneol (2-MIB) in water. Chlorination hardly removed geosmin and 2-MIB, while the UV/chlorine reaction at 254 nm completely removed geosmin and 2-MIB within 40 min and 1 h, respectively, with

Degradation of 2-MIB in aqueous solution by ZnOOH catalyzed ozonation
Journal of Water Supply: Research and Technology-Aqua, 2013In this study, ZnOOH was used as a catalyst and its efficiency in removing trace organic matter, 2-methylisoborneol (2-MIB), in conjunction with ozone was investigated. The catalyst was characterized by X-ray diffraction (XRD), the Brunauer-Emmet-Teller (BET) method and Fourier transform infrared spectrometry (FT-IR).

Cyanobacteria are the major producers of the taste and odour compounds geosmin and 2-methylisoborneol (2-MIB) in drinking water and fish worldwide. In recent years, the outbreaks of cyanobacteria blooms in Tri An and Dau Tieng Reservoirs, Vietnam have led to an increase attention in taste and odour problems.

Removal of 2-MIB and geosmin using UV/persulfate: contributions of hydroxyl and sulfate radicals.
Water Research, 20152-methylisoborneol (2-MIB) and geosmin are two odor-causing compounds that are difficult to remove and the cause of many consumer complaints. In this study, we assessed the degradation of 2-MIB and geosmin using a UV/persulfate process for the first time.

Effect of pH on the Analysis of 2-MIB and Geosmin in Water
Water, Air, & Soil Pollution, 20122-Methylisoborneol (2-MIB) and trans-1,10-dimethyl-trans-9-decalol (geosmin) are two commonly observed taste and odor compounds present in drinking water sources. The effects of pH on the analysis of the two chemicals are investigated using a gas chromatograph and mass spectrometric detector (GC/MSD) coupled with three pre-concentration methods, namely

Dechlorination techniques to improve sensory odor testing of geosmin and 2‐MIB
Journal AWWA, 2003Chlorine in finished water can mask the more subtle odors of geosmin and 2‐methylisoborneol (2‐MIB), two chemicals that often trigger consumer complaints when present at even nanogram‐per‐litre concentrations. These are two of the odors that are revealed as chlorine dissipates in the distribution system, which is typically at the consumer's end.

Quick Response to 2-MIB Episodes Based on Native Population Odor Sensitivity Evaluation
CLEAN – Soil, Air, Water, 2014Taste and odor have been a recurring problem for many water utilities. This paper established an optimized strategy to cope with 2‐methylisoborneol (2‐MIB) by combining the determination of the control goal according to native population sensitivity and the prediction of the optimum powdered activated carbon (PAC) dose using the homogeneous surface ...
