Flame photometric analysis technology has been proven to be a rapid and sensitive method for sulfur and phosphorus detection. It has been widely used in environmental inspections, pesticide detection, industrial and agricultural production. By improving the design of the traditional flame photometric detector, using grating and CCD sensor array as a photoelectric conversion device, the types of compounds that can be detected were expanded. Instead of a single point of characteristic spectral lines, full spectral information has been used for qualitative and quantitative analysis of H2S, PH3, NH3, AsH3 and Cl2. Combined with chemometric method, flame photometric analysis technology is expected to become an alternative fast, real-time on-site detection technology to simultaneously detect multiple toxic and harmful gases.

In this study, a preconcentration strategy based on Ni(OH) nanoflowers (NFs) was developed for the extraction/separation of bismuth ions from environmental water samples before the determination by flame atomic absorption spectrometry (FAAS). The homogeneous coprecipitation method was employed for the synthesis of the flower-shaped Ni(OH) and used as an adsorbent for the preconcentration of bismuth. The extraction variables were determined by a univariate optimization strategy to obtain maximum extraction performance.

Humans are exposed to potentially toxic mercuric mercury (Hg) and methylmercury (MeHg) by the ingestion of food, to the bactericidal vaccine additive thimerosal (THI), and/or to the antifungal compound phenylmercuric acetate (PMA) which is used in some lens cleaning ophthalmic fluids. While numerous HPLC methods have been developed to separate Hg and MeHg in environmental samples (e.g.

Eucalyptus essential oil is widely valued for its therapeutic properties and extensive commercial applications, with its chemical composition significantly influenced by species variety, geographical origin, and environmental conditions. This study aims to develop a reliable method for identifying the geographical origin and variety of eucalyptus oil samples through the application of advanced analytical techniques combined with chemometric methods. Essential oils from Eucalyptus globulus and Eucalyptus camaldulensis were analyzed using Gas Chromatography-Flame Ionization Detection (GC-FID) and Fourier Transform Infrared (FTIR) Spectroscopy.

Cotton fibers' flammability and rapid combustion greatly restrict their usage in industries that require higher flame retardancy. Phosphorus and nitrogen-based flame retardants are frequently employed in the textile industry to consolidate the flame resistance of cotton materials. To consolidate flame retardant performance, a novel flame retardant named HPAPU was synthesized by combining 3-hydroxyphenylphosphinylpropionic acid, 1,6-hexanediamine, phosphoric acid, and urea.
