“…Compared with the volumetric method, the cyanomercuric sulfate photometric method has the characteristics of higher sensitivity and efficiency, but the interference of halogen elements is high, and the test uses mercury-containing reagents, which is not friendly to the environment. Therefore, many scholars have studied silver nitrate turbidimetry, which uses the positive correlation between the absorbance value of the suspension generated by the reaction of Cl − and silver nitrate to determine Cl − concentration [57][58][59]. However, the silver chloride precipitation is unstable, and stabilizers such as polyethylene glycol, glycerin, macrodextrin, and Twean-80 are usually added to the reaction to stabilize the suspension; the precipitation generation is greatly affected by temperature, so controlling a certain reaction temperature is also key [60].…”

“…The adsorption of Cl − in the PCN gap will cause the fluorescence attenuation of the semiconductor, so the material has potential value for the detection of Cl − . Zhang et al [58] used silver to modify PCN to obtain silver-modified carbon nitrite nanosheets. This material had high porosity and coordination function and was more likely to adsorb Cl − in water compared with the single PCN, thus improving fluorescence detection performance.…”

The chloride ion (Cl−) is a type of anion which is commonly found in the environment and has important physiological functions and industrial uses. However, a high content of Cl− in water will do harm to the ecological environment, human health and industrial production. It is of great significance to strictly monitor the Cl− content in water. Following the recent development of society and industry, large amounts of domestic sewage and industrial sewage are discharged into the environment, which results in the water becoming seriously polluted by Cl−. The detection of Cl− has gradually become a research focus. This paper introduces the harm of Cl− pollution in the environment and summarizes various Cl− detection methods, including the volumetric method, spectrophotometry method, electrochemical method, ion chromatography, paper-based microfluidic technology, fluorescent molecular probe, and flow injection. The principle and application of each technology are described; their advantages, disadvantages, and applicability are discussed. To goal of this research is to find a more simple, rapid, environmental protection and strong anti-interference detection technology of Cl−.

“…It is clear that the diffraction peaks at 2⊔ = 25.1°, 37.8°and 48.1°correspond to TO nanoparticles and are respectively indexed to (101), (004) and (200) crystal planes of anatase. 37 The XRD pattern of CF/TO-FND nanocomposite shows some additional peaks at 43.7°and 73.5°representing the presence of FND. These peaks are respectively indexed to (111) and (220) plane of diamond lattice.…”

Titanium oxide (TO)-and functionalized nanodiamond (FND)-reinforced carbon foam (CF) composites were prepared by the direct pyrolysis of TO, FND and a mixture of mesophase coal tar pitch. The effects of TO and FND loadings on the microstructure and functional properties of the CF composites were studied. The obtained microstructures of the CF composites showed that both nanofillers have an influential role in the formation of porous morphology of CF. Moreover, the additive aspects of TO and FND were further studied in terms of mechanical, thermal and electrical properties. The results revealed that compressive strength increased up to 20.21 MPa, thermal conductivity was as high as 32.33 W m −1 K −1 at elevated temperature and electrical conductivity was 23.24 × 10 3 S m −1 . The results show that FND particles are well appropriate to meliorate the fabrication of TO nanoparticles in CF to build up a solid connection between the nanoparticles and CF for the improvement of the mechanical, thermal and electrical properties of CF composites.

In this novel research work, for the first time, green g-C 3 N 4 nanocomposites have been synthesized by utilizing Eriobotrya japonica as a stabilizer and mediator. Based on DRS absorbance spectra, TGA, fluorescence spectra related to •OH amount, photoelectrochemical curves, TPD, and BET results, it has been confirmed the Eriobotrya japonica mediated green g-C 3 N 4 (G-CNS) nanosheets are efficient, stable, and more than 2.4 times enhancement in activities as compared with conventional chemically synthesized g-C 3 N 4 nanosheets. In order to further improve the performance, the as-synthesized green g-C 3 N 4 was modified with SnO 2 nanosheets. Our results confirmed that coupling of SnO 2 nanosheets prolonged the lifetime of charge carriers and provided catalytic function. Compared with pristine G-CNS, the photocatalytic activity of the resulting 5SO/G-CNS improved by 2.3 and 2.6 times, for doxycycline and rhodamine B degradation, respectively. In addition, the possible photodegradation pathway for doxycycline and RhB mineralization is proposed. Finally, this novel work will provide a new platform for the efficient green synthesis of g-C 3 N 4 based nanocomposite and its utilization for environmental remediation.
