The application belongs to the field of mineral flotation, and particularly discloses a composite branched alkyl salicylhydroxamic acid collector and a flotation application thereof. The composite branched alkyl salicylhydroxamic acid collector comprises formula 1A (1A), formula 1B (1B) and formula 1C (1C). The branched alkyl is introduced into the collector, so that the hydrophobic ability and the collecting ability are improved, and the separation and enrichment of strategic metal oxide minerals such as copper, iron, tin, tungsten, titanium and rare earth are improved.

The invention discloses a water treatment method for a retainer after spraying an antirust agent, and belongs to the technical field of industrial sewage treatment. The method comprises the following steps: adjusting the pH value of water after spraying an anti-rust agent on a retainer, carrying out primary filter pressing to remove large-particle impurities in sewage, conveying a mixed solution of modified activated carbon and water and the sewage into a stirring cylinder for stirring, carrying out secondary filter pressing, and carrying out secondary filter pressing to remove large-particle impurities in the sewage. After being treated by modified chitosan, the water is conveyed into a precipitation tank, sodium hypochlorite is added, the water is left to stand in the precipitation tank, and treated water is obtained; the modified chitosan is obtained by modifying salicylhydroxamic acid and trihydroxybenzoic acid. According to the treatment method, metal ions and particle impurities in the sewage can be removed, the influence on a water-based antirust agent system is small, the water-based antirust agent is reserved in the treated water to the maximum extent, the treated water is used in a water-based antirust agent spraying process, the utilization rate of water resources and the water-based antirust agent is increased, and then the production cost is reduced.

The invention relates to the technical field of corn dehydration, in particular to application of salicylhydroxamic acid in promoting corn kernel dehydration. The embodiment of the invention provides application of salicylhydroxamic acid in promoting dehydration of corn kernels for the first time. When the salicylhydroxamic acid is applied to the corn, on the premise that the yield of the corn is not affected, the grain filling and maturing process can be accelerated, the dehydration rate of the corn grains is remarkably increased, and the water content of the grains is effectively reduced.

The application discloses a hydroxamic acid-quaternary ammonium salt ionic liquid collector and a preparation method and application thereof. The structural formula of the hydroxamic acid-quaternary ammonium salt ionic liquid collector is shown as formula (I): (I). The hydroxamic acid-quaternary ammonium salt ionic liquid collector has good collecting property and selectivity to rare earth ores compared with traditional salicylhydroxamic acid collectors, and can still achieve good collecting effect without adding a foaming agent, and has a wide application prospect.

The invention belongs to the technical field of metal salicylhydroxamic acid molecular cage complex materials, and particularly discloses a metal salicylhydroxamic acid molecular cage for detecting metronidazole and a preparation method and application of the metal salicylhydroxamic acid molecular cage. The structural general formula of the metal salicylhydroxamic acid molecular cage is {M2Ga8 (shi) 8 (X) 4}; wherein M is one of lanthanide series rare earth metal elements; shi represents a salicylhydroxamic acid ligand; x is a dicarboxylic acid ligand. Compared with the prior art, the prepared metal salicylhydroxamic acid molecular cage has a specific cavity and skeleton structure, adsorption and aggregation of small molecular compounds can be achieved, and due to the fact that rare earth elements emit light, the content of the small molecular compounds can be detected through fluorescence intensity changes. The molecular cage provided by the invention is used for fluorescence sensing detection of the content of metronidazole in wastewater, and has the advantages of high sensitivity, fast response and the like.
