The paper presented demonstrates the calibration of a silicone membrane probe for measurement of hydrogen sulphide in liquid and gas phase. The probe is connected to a quadrupole mass spectrometer as detector. The calibration of the probe results in linear calibration functions for different liquids and the gas phase. An example of the application of the measuring device for on-line measurement is reported for an experiment where sulphide is precipitated as iron sulphide by the addition of…

Abstract An on-line monitoring system has been developed for the control of a biorreactor for the anaerobic pretreatment of an industrial waste water. The monitoring system is based on a process mass
A simple method for the determination of hydrogen sulfide concentration in beer
We have evaluated a hydrogen sulfide (H 2 S) analyzer equipped with a gas-permeable tube as a possible method for the rapid determination of H 2 S in beer (HSA method). The H 2 S analyzer responded
Effects of chemical amendments on the lability and speciation of metals in anaerobically digested biosolids.
Experiments were conducted to investigate whether the addition of iron- and aluminum-based amendments during the anaerobic digestion phase of wastewater treatment can effectively change the speciation or lability of contaminant metals in biosolids destined for use in agriculture.
An innovative intermittent-vacuum assisted thermophilic anaerobic digestion process for effective animal manure utilization and treatment.
Intermittent-vacuum stripping-TAD combination could be an effective strategy to improve TAD efficiency, whose elution is more easily utilized in algae cultivation and/or hydroponic system.
