Degradation of 2-MIB in aqueous solution by ZnOOH catalyzed ozonation

Journal of Water Supply: Research and Technology-Aqua, 2013
In 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).

Study on the Effect of Different Water Treatment Technology on Removing 2-MIB

Applied Mechanics and Materials, 2014
To compare the removal efficiency of 2-MIB by traditional water treatment, prechlorination, O3-BAC, MIEX pre adsorption and UV/H2O2 advanced oxidation process, the pilot-test of drinking water odor control technology were studied in this paper. The results showed that the traditional water treatment process had poor effect on removing 2-MIB, with about

Dechlorination techniques to improve sensory odor testing of geosmin and 2‐MIB

Journal AWWA, 2003
Chlorine 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.

The effect of light availability and light wavelength on growth, 2-MIB biosynthesis, and 2-MIB-related gene expression in Pseudanabaena foetida var. intermedia

Archives of Microbiology
2-methylisoborneol (2-MIB) is an odiferous metabolite mainly produced by cyanobacteria, contributing to taste and odor problems in drinking water. The mechanisms involved in 2-MIB biosynthesis in cyanobacteria are not yet completely understood. This study investigated the effect of light availability and wavelength on growth, 2-MIB synthesis, and ...

Physiological and transcriptomic changes of zebrafish (Danio rerio) embryos-larvae in response to 2-MIB exposure

Journal of Hazardous Materials, 2021
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

Pediatric Medulloblastoma: Prognostic Value of p53, bcl-2, Mib-1, and Microvessel Density

Journal of Neuro-Oncology, 1999
The aim of this study was to retrospectively assess the prognostic value of p53 and bcl-2 protein expression, cell proliferation index (Mib-1 index), and tumor microvessel density (factor VIII-related antigen) in pediatric medulloblastoma patients.

Efficiency and Mechanism of Degradation of 2-Methylisoborneol(2-Mib) by O3/H2O2 in Water

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010
Abstract-The research on efficiency and mechanism of removing the odor compound 2-MIB in water is performed by adopting the O3/H2O2 technology. And in particular, the effects of addition manner, mol ratio, pH value of the solution and water quality etc, on the 2-MIB degradation are studied.

First report of geosmin and 2-methylisoborneol (2-MIB) in Dolichospermum and Oscillatoria from Vietnam

Limnology, 2020
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.

[Source and fluctuation of trace geosmin and 2-MIB in drinking water of Shanghai].

Huan jing ke xue= Huanjing kexue, 2009
Liquid-liquid microextraction/GC/MS analysis method was employed in detecting trace odorants in drinking water. A-year-long investigation on odor chemicals was carried out in source water and drinking water in a certain waterworks of Shanghai. The results showed that 2-MIB was the main contaminant which induce disgusting odor to drinking water of ...

Correlation of musty odor and 2-MIB in two drinking water treatment plants in South Taiwan

Science of The Total Environment, 2002
Possible odor groups and intensity, and seasonal effects were elucidated in two representative water treatment plants (WTPs), Feng-Shen and Gun-Shi, in southern Taiwan. The flavor profile analysis (FPA) was employed to determine the odor groups for the source water, while a chemical analysis, solid-phase microextraction (SPME) coupled with a gas ...
