Preface Sulfur compounds are key odor-causing and toxic/harmful pollutants in ambient air, mainly released via fugitive emissions from the chemical, petrochemical, wastewater treatment, waste disposal and pharmaceutical industries. Their extremely low odor threshold means even trace concentrations ...

Preface Human milk oligosaccharides (HMOs) are a group of oligosaccharides with a degree of polymerization no higher than 3, naturally present in human milk; they are the third largest solid component in human milk, after lactose and fat. They regulate the intestinal flora—particularly promoting the ...

Hexavalent chromium possesses high toxicity, carcinogenicity, and bioaccumulative potential. If the content of hexavalent chromium in dyes exceeds the permissible limit, it will not only contaminate the production environment and endanger the health of operators during textile dyeing and processing, ...

Methionine Hydroxy Analogue (MHA) is an organic acid additive widely used in the feed industry as a substitute for methionine. MHA is widely used in the feed of poultry (broilers and layers), swine (piglets and finishing pigs), ruminants (dairy cattle and beef cattle), and aquaculture (fish and ...

Caffeine is a natural methylxanthine alkaloid widely present in raw materials such as coffee beans, tea leaves, and cacao beans. It serves as a core functional additive and characteristic flavor compound in commercially available beverages, including carbonated drinks, energy drinks, tea-based ...

Ion chromatography (IC) offers high sensitivity and high selectivity, enabling the accurate determination of low-concentration toxic and hazardous ions in petroleum wastewater, such as heavy metal cations and high-concentration chloride (Cl⁻). This technology provides accurate data for compliant ...

Organic amine absorption solutions are a class of weakly alkaline organic amine solvents commonly used in chemical processes such as petroleum refining, natural gas processing, coal chemical industry, and ammonia synthesis, for capturing carbon dioxide from flue gases, as well as for adsorbing and ...

Triazine pesticides are organic compounds containing a triazine ring, used primarily as herbicides and insecticides. Most triazine herbicides act by inhibiting the D1 protein in photosystem II (PSII), blocking the electron transport chain and preventing the synthesis of ATP and NADPH, leading to ...

Glyphosate aqueous solutions, as non-selective herbicides, have their herbicidal efficacy directly correlated with the contents of active ingredients and salt-forming ions. If the contents of isopropylamine ions or dimethylamine ions in the product fail to meet the specified standards (i.e., do not ...
