Abstract This review will illustrate how it is possible to develop ion‐selective electrode (ISE) methodologies that meet the stringent requirements (i.e., high selectivities and very low detection limits) for analysis of important analytes in environment, present a variety examples on application ISEs environmental analysis. Despite experimental biases have limited analytical performance through apparently limits modest selectivities, there has been plethora research monitoring...
The direct qualitative and quantitative determination of mineral components in shale rocks is a problem that has not been satisfactorily resolved to date. Infrared spectroscopy (IR) non-destructive method frequently used identification, yet challenging due the similarity spectral features resulting from quartz, clay feldspar minerals. This study reports on significant improvement this methodology by combining infrared attenuated total reflection (IR-ATR) with partial least squares (PLS)...
Reflectance spectroscopy allows cost-effective and rapid mineral characterisation, addressing exploration mining challenges. Shortwave (SWIR), mid (MIR) thermal (TIR) infrared reflectance spectra are collected in a wide range of environments scales, with instrumentation ranging from spaceborne, airborne, field drill core sensors to IR microscopy. However, interpretation is, due the abundance potential vibrational modes assemblages, non-trivial requires thorough understanding factors...
An on-line infrared sensor system for monitoring greenhouse gases in brine environments is demonstrated. Evident changes of distinctive signatures dissolved methane and carbon dioxide under conditions relevant gas storage are shown, which particular relevance understanding their subsurface behaviour after injection during capture (CCS) processes.
A new class of CO<sub>2</sub> sorbents, namely polyethylenimine hydrogel beads (PEI HBs), has been developed <italic>via</italic> a simple one-step crosslinking reaction PEI using epichlorohydrin (EPC).
The AIHs are formed in 300 seconds by mixing hydrogel particles with liquid amine (left) which increases the contact area between CO<sub>2</sub> and (right).
We report the rapid and scalable preparation of PEI snow that can remove CO<sub>2</sub> from air under industrial conditions.
The development of chemical sensors for monitoring the levels organic pollutants in aquatic environment has received a great deal attention recent decades. In particular, mid-infrared (MIR) sensor based on attenuated total reflectance (ATR) is promising analytical tool that been used to detect variety hydrocarbon compounds (i.e., aromatics, alkyl halides, phenols, etc.) dissolved water. It shown under certain conditions MIR-ATR capable achieving detection limits 10-100 ppb concentration...
An infrared attenuated total reflection (IR-ATR) method for detecting, differentiating, and quantifying hydrocarbons dissolved in water relevant oil spills by evaluating the "fingerprint" of volatile organic compounds (VOCs) associated with individual types mid-infrared spectral range (i.e., 800-600 cm(-1)) is presented. In this regime, these provide distinctive absorption features, which may be used to identify specific hydrocarbon patterns that are characteristic different crude refined...
The use of mid-infrared sensors based on conventional spectroscopic equipment for oil spill monitoring and fingerprinting in aqueous systems has to date been mainly confined laboratory environments. This paper presents a portable-based attenuated total reflectance (MIR-ATR) sensor system that was used quantify number environmentally relevant hydrocarbon contaminants marine water. comprises polymer-coated diamond waveguide combination with room-temperature operated pyroelectric detector, the...
An in situ surface study of the carbon dioxide corrosion mild steel has been undertaken using tandem technique mixed potential/synchrotron radiation-grazing incidence X-ray diffraction (SR-GIXRD). Long-term monitoring potential showed there was an initial shift toward cathodic potentials attributable to preferential suppression half-reaction (viz., reduction carbonic acid), probably due formation adlayer product physically blocking reaction sites during uniform steel. Subsequently, displayed...
