Terephthalic acid capped iron oxide nanoparticles for sensitive electrochemical detection of heavy metal ions in water

Iron Sand as a Heat Absorber to Enhance Performance of a Single-Basin Solar Still

“…For instance, one experimental study of carbon powder used charcoal particles as an absorber medium and increased the productivity of a solar still by up to 15% [7]. El-Sebaii used sand as a sensible storage material under the basin liner [8], and in another study, sand was used instead of servotherm medium oil as a sensible heat storage material, placed beneath the basin liner [9]. In another study, there was as much as a 35% improvement in a solar still that used carbon powder as a porous solar absorber [10].…”

Simultaneous Determination of Cd2+, Cu2+, Pb2+ and Hg2+ Based on 1,4‐Benzenedithiol‐2,5‐diamino‐hydrochloride‐1,3,5‐triformylbenzene Covalent‐Organic Frameworks

“…In order to save time, people have developed a variety of technologies to realize the simultaneous detection of HMIs in the water. Since the reduction potentials of HMIs is different, electrochemical methods are easier to realize simultaneous detection of HMIs [17] . However, the application of the traditional electrochemical methods in HMIs determination is hindered by several problems, such as the low resolution between the reduction peaks of several HMIs and the limited sensitivity [18] .…”

Europium doping effect on 3D flower-like SnO2 nanostructures: morphological changes, photocatalytic performance and fluorescence detection of heavy metal ion contamination in drinking water

“…Among various metal oxide semiconductors, SnO 2 , 6 CeO 2 , 7 and Fe 2 O 3 (ref. 1) are probably the most common materials used for heavy metal ion detection and as leading photocatalysts because of their photochemical stability, low cost, non-toxicity and simple preparation.…”
