## Description

- description: " Volatile fatty acids (VFAs) are important intermediates in the decomposition
    processes of organic wastes. The detection of VFAs is an indispensable procedure
    to monitor anaerobic digestion in biogas production. However, the direct, rapid,
    and sensitive detection of VFAs remains a challenge. Herein, we report the proof-of-concept
    use of a newly developed membrane-covered moisture sensor (MMS) composed of a
    moisture sensor chip (MSC) integrated with a hydrophobic polytetrafluoroethylene
    (PTFE) membrane toward the rapid direct detection of VFAs in aqueous solutions.
    The detection of propionic acid (PA), a typical VFA, was investigated using two
    methods: Raoult's law-driven evaporation and heating-induced evaporation. The
    results revealed that the current detected from the transport of gaseous PA through
    PTFE membrane pores and the subsequent accumulation within MSC electrodes depended
    on the PA concentration in the gas phase and the controlled temperature. The proposed
    MMS is speculated to be applicable for detecting VFAs in landfill processes."
