Abstract
The invention discloses a manganese-containing formaldehyde detection reagent and a preparation method thereof. The manganese-containing formaldehyde detection reagent comprises a first reagent and a second reagent, wherein the first reagent comprises the components in parts by weight: 40-60 parts of sulfamide benzoic acid, 50-70 parts of isocyanate, 90-100 parts of an organic solvent, 20-40 parts of amino acid chelate manganese, 10-20 parts of monopotassium phosphate and 60-90 parts of parabromobenzoic acid; the second reagent comprises the components in parts by weight: 30-40 parts of primary arylamine, 40-60 parts of cyclic carboxylic acid, 80-120 parts of inorganic salt, 20-50 parts of succinic acid, 20-30 parts of superphosphate and 80-100 parts of a pyridine derivative. The preparation method comprises the steps: diluting the first reagent by 90-100 times, adding the second reagent, and uniformly mixing the reagents. The detection reagent disclosed by the invention can be used for quickly detecting whether the formaldehyde content is overproof, and the operation is carried out by only 49-54 seconds; compared with the prior art, the manganese-containing formaldehyde detection reagent disclosed by the invention is higher in detection efficiency.
