“…(2) Fenton reagent method Fe 2+ or Fe 3+ as a catalyst, in the presence of H 2 O 2 produced by the strong oxidation, can make many organic molecules oxidized, and the reaction system does not require high temperature and high pressure, the reaction conditions are not harsh, the reaction equipment is also relatively simple, the scope of application is wider [40]. In recent years, some scholars have introduced ultraviolet light (UV), oxalate, etc.…”

Wastewater treatment is an important aspect of the dyestuffs industry, as the process of dye production generates a large amount of wastewater containing various organic and inorganic pollutants. To protect the environment, effective wastewater treatment methods, such as chemical oxidation and biodegradation, are needed to remove pollutants from the wastewater and to meet the discharge standards. This paper reviews the research progress of dye wastewater treatment methods, including flocculation and precipitation, oxidation, electrochemistry, biodegradation, adsorption, etc. The different treatment methods are introduced and their current status and advantages and disadvantages are reviewed. Chemical methods have short treatment time and good effect, but the process is complicated and not easy to operate, and the intermediate products produced may have greater toxicity; biological methods have the advantages of environmental protection and mild conditions, but the treatment time is generally longer, and the poor biochemistry of many dyestuffs restricts the use of biological methods; physical methods have been widely used because of their simple operation and adaptability, among which adsorption is commonly used in the decoloration treatment of wastewater. Undoubtedly these researches are of great significance in recognizing the nature and characteristics of pollutants and mastering the principles and methodological features of environmental treatment technologies.

“…The American Conference of Governmental Industrial Hygienists (ACGIH) proposes a threshold limit of 1 ppm . Chromatography and colorimetric techniques , are the traditional methods applied to detect TEA, which have disadvantages such as time consumption, high cost, and complex operation. Hence, a rapid, accurate, high-sensitivity, and ppb-level limit of detection (LOD) technology is urgently needed.…”

The detection of harmful volatile organic compounds is of great significance to environmental quality and human health. However, it still remains a challenge to achieve high detection sensitivity at a relatively low temperature. Herein, an ultrasensitive catalytic sensor for the detection of triethylamine (TEA) based on ZnO/ PtO/Pt nanoarray thin films was realized. Sensor measurements reveal that the PtO/Pt sensitizer dramatically reduces the working temperature from 195 °C of a pristine ZnO sensor to 125 °C of ZnO/PtO/Pt sensors. The ZnO/PtO/Pt sensors exhibit an extremely high response of 3513 to 50 ppm TEA, which is three orders of magnitude higher than that of pristine ZnO. Meanwhile, an ultralow limit of detection of 8.3 ppb is achieved. The outstanding performances are superior to those in most previous reports on TEA detection. Mechanistic investigations reveal that the outstanding performances are ascribed to the strong electronic interaction between PtO and ZnO and the catalytic spillover effect of Pt.
